Nike Sizing Guide (2026) | I Tested 90+ Sneakers: True to Size or Not?

If you’re trying to figure out your Nike sizing or find your Jordan size, here’s the short version.

Most Nike sneakers fit true to size, but there are some key exceptions you need to know.

The Nike Air Force 1 usually runs big, so going half a size down works best for most people.

On the flip side, models like the Nike SB Dunk Low, Nike Air Max 95, and Nike Air Max 97 tend to run snug, so going half a size up will feel much more comfortable.

From my experience, Jordans are more consistent. The Air Jordan 1 fits true to size, while models like the Air Jordan 4 can feel a bit narrow depending on your foot width, and the Air Jordan 6 actually runs slightly big, so I prefer going half a size down there.

So if you’re just looking for quick answers, right below, you’ll find a full sizing table with every model covered.

If you’re just trying to find one specific pair, just scan the table or use the search shortcut to jump straight to it:

Nike Sizing Guide

Nike Air Force 1 Sizing

In my experience, the Nike Air Force 1 runs a bit big, so I’d recommend going half a size down for most people.

The toe box has more space than most Nike models, and the overall fit feels more relaxed on foot. When I wear my true size 9, I get close to a full finger’s width in front of my toes, which feels a bit too roomy for me.

Because of that, I usually go half a size down to 8.5, and that’s where the fit really starts to feel dialed in. It becomes more secure, and you still get enough room for comfort.

If you have narrow or normal feet, I’d definitely go half a size down. That’s where this shoe feels the best. If you have slightly wide feet, I still think sizing down works in most cases because the shape is already forgiving.

Now, if you have really wide feet or you prefer a more relaxed fit, staying true to size can make more sense. That extra space will actually work in your favor.

One thing to keep in mind is that not every Air Force 1 fits exactly the same. Some pairs feel more padded, some feel slightly tighter, and certain collabs can change the fit a bit.

So what would I do?

I’d go half a size down in most Air Force 1s. That’s the safest move for most people.

Quick takeaway:

• Half size down for most people
• True to size for wide feet or if you like more room

Now, if you’re more into running shoes, my Asics sizing guide will help you a lot. Asics can feel very different depending on the model, especially with how snug some of their runners can be.

Air Force 1 Low “Four Horsemen” Sizing

This pair actually surprised me.

In my experience, the Air Force 1 Low “Four Horsemen” fits more true to size than expected, even though I still went half a size down.

Normally, AF1s feel roomy, but here my toes were sitting much closer to the front than usual. That’s not typical for this model.

It could just be my pair, but it’s worth knowing that not every Air Force 1 fits exactly the same.

So even though I’d still go half a size down, expect it to feel a bit more snug and less roomy than a standard AF1.

Quick takeaway:

• Half size down still works
• Feels more snug than typical Air Force 1

Air Force 1 Craft Sizing

The Air Force 1 Craft still runs slightly big, so I’d go half a size down like usual.

This version has a bit more structure and a more premium feel, but the sizing stays consistent. I went half a size down, and it felt snug in a good way. Secure, clean, and not tight.

Even with the slightly more padded build, I never felt like I needed to go true to size.

If you’ve worn regular AF1s before, the same sizing applies here.

Quick takeaway:

• Half size down
• Same sizing as regular Air Force 1

Tiffany & Co. x Air Force 1 “1837” Sizing

This one fits exactly how I expect an Air Force 1 to fit.

It runs slightly big, so I went half a size down, and the fit felt spot on.

I had about a finger’s width in the toe box, and the width didn’t give me any issues at all. It felt balanced and comfortable.

If you like a snug, one-to-one fit, half a size down is the move here. If you have wider feet or you prefer more space, true to size will still work.

Quick takeaway:

• Half size down for most people
• True to size for more room

Nocta x Air Force 1 Low SP Sizing

Same story here.

This collab runs slightly big, so I went half a size down, and the fit felt great. Nothing about this pair made me want to change sizing.

If you have wide feet, you can stay true to size, but for most people, half a size down is still the best option.

Quick takeaway:

• Half size down
• True to size for wide feet

Air Force 1 ’07 Premium Sizing

This pair felt slightly different.

The AF1 ’07 still runs a bit big, but the toe box feels slightly shorter than usual, even when going half a size down.

My foot sat closer to the front than I expected. It wasn’t uncomfortable, but it did feel tighter compared to a typical AF1.

That said, I still wouldn’t jump to true to size. The overall shape is still roomy enough to justify sizing down.

Quick takeaway:

• Half size down
• Slightly snugger than typical AF1

Air Jordan Sizing

Air Jordan 1 Retro High OG Sizing

The Air Jordan 1 High OG fits true to size for most people.

I wear a size 9, and that’s exactly what works for me here. The fit feels balanced, not too tight, not too roomy.

If you have narrow, normal, or slightly wide feet, I’d stick with your regular size.

If you have really wide feet, you might feel some tightness around the forefoot, especially near the lace area. In that case, half a size up can help.

Quick takeaway:

• True to size
• Half a size up for wide feet.

Air Jordan 1 Retro Low OG Sizing

The Jordan 1 Low OG runs slightly bigger than the High.

I went true to size, and it felt a bit roomier than expected, especially in length.

If you like a snug, one-to-one fit, going half a size down can feel better.

If you don’t mind a bit of extra space or you have wider feet, true to size still works fine.

Quick takeaway:

• True to size for a relaxed fit
• Half a size down for a snug fit.

Travis Scott x Air Jordan 1 Low OG SP Sizing

This is a women’s release, so you’ll need to convert your size. Go up 1.5 sizes to match your men’s size.

Once you get the right size, the fit feels just like a regular Jordan 1 Low OG.

I went with my usual size (after conversion), and the fit felt right.

Some people say the Jordan 1 Low runs a bit roomy, but for me, true to size works every time.

Quick takeaway:

• Convert your size correctly, then go true to size.

Air Jordan 1 Lost and Found Sizing

In my experience, the Air Jordan 1 Lost and Found fits true to size for most people.

This pair sits somewhere between the modern Jordan 1 shape and the slightly slimmer 1985 cut, but the sizing itself doesn’t really change.

I went with my true size 9, and the fit felt exactly how I expect a Jordan 1 to feel.

There’s enough room in the toe box, and the overall shape feels familiar if you’ve worn Jordan 1s before.

If you have narrow or normal feet, I’d stick with your regular size without overthinking it. If your feet are slightly wide, true to size should still work.

If you have really wide feet, though, I do think going up half a size makes sense. The toe box can feel a bit snug on the sides.

Quick takeaway:

• True to size for most people
• Wide feet may want half a size up
• Same sizing as most Air Jordan 1s

If you’ve worn Jordan 1s before, nothing here will surprise you.

Trophy Room x Air Jordan 1 Retro Low OG Sizing

In my opinion, this one still fits true to size, but it feels a bit more snug than your typical Jordan 1 Low OG.

I went with my true size 9, and right away I noticed the difference. The materials seem to make the shoe feel tighter, especially around the toe box and along the lateral side.

It’s not unwearable, but it definitely feels more restrictive than a standard pair.

If you have narrow or normal feet and you usually go half size down in Jordan 1 Lows, you can stick with that same approach here.

But if your feet are even slightly wide, I would not go half size down on this pair. I’d stay true to size to avoid that tight feeling up front.

Quick takeaway:

• True to size is the safer choice
• Runs a bit snug compared to regular Jordan 1 Lows
• Avoid sizing down if you have wider feet

Air Jordan 1 Low 85 Sizing

I’d say the Jordan 1 Low 85 fits more snug than your typical Jordan 1 Low, so sizing depends more on your foot shape here.

I noticed that the shape is tighter overall, especially through the forefoot. When I tried them, the width felt more restrictive than usual.

Lengthwise, you still get enough space, but the shoe hugs your foot more.

If you have narrow or normal feet, you can stay true to size and it should feel fine.

If you have wider feet, I think going up half a size makes a lot more sense. Yes, you’ll get a bit more length, but the extra width is worth it.

Quick takeaway:

• Narrow/normal feet: true to size
• Wide feet: half size up
• Feels snugger than standard Jordan 1 Lows

Air Jordan 1 High Element (Gore-Tex) Sizing

In my experience, this one fits true to size in length, but noticeably snug in width.

I went true to size, and the first thing I noticed was how tight it felt around the sides of my foot. The Gore-Tex build makes the upper feel a bit more structured and less forgiving.

The length and heel feel like a normal Jordan 1, but the width is where you’ll notice the difference.

If you have narrow or normal feet, you can stick with your usual Jordan 1 size.

If you have wider feet, I do think going up half a size is the better move here.

Quick takeaway:

• True to size for narrow/normal feet
• Wide feet should go half size up
• Snugger than regular Jordan 1s

Air Jordan 1 High Stealth Sizing

This one is simple. The Air Jordan 1 High Stealth fits true to size.

Jordan 1 sizing is usually very consistent, and this pair follows that pattern. The leather feels soft right out of the box, so the shoe already feels broken in.

I went with my usual size and had no issues at all.

If you’ve worn Jordan 1s before, just stick with that same size.

Quick takeaway:

• True to size
• Standard width
• Comfortable everyday fit

Air Jordan 2 Retro Sizing

In general, the Air Jordan 2 fits true to size, but it feels a bit more snug than a Jordan 1.

I stuck with my usual size, and the fit felt secure without being uncomfortable.

There’s a bit more structure in the upper, so it wraps your foot more closely.

If you have narrow or normal feet, true to size is the way to go.

If you prefer a roomier fit or have wider feet, you could consider going up half a size, but most people won’t need to.

Quick takeaway:

• True to size for most people
• Slightly snug fit compared to Jordan 1
• Half size up only if you want extra room

Air Jordan 2 Retro Low Sizing

I found the Jordan 2 Low fits true to size, but again, slightly snug.

I went with my usual size and it felt secure, especially compared to something like a Jordan 1 Low, which feels more relaxed.

The shape hugs your foot a bit more, especially through the midfoot.

If you have narrow or normal feet, true to size should feel great.

If you have wider feet, going up half a size might give you a more comfortable fit.

Quick takeaway:

• True to size for most
• Snugger than Jordan 1 Low
• Wide feet may want half size up

Air Jordan 3 Retro Sizing

In my experience, the Air Jordan 3 fits true to size, but slightly snug depending on the release.

I converted to my men’s equivalent size and the fit felt good overall, but a bit tighter than some other Jordan 3s I’ve worn.

The shape feels more structured, which gives you that close, secure fit.

If you have narrow or normal feet, true to size is the right call.

If you have wider feet, I’d consider going up half a size.

Quick takeaway:

• True to size for most
• Slightly snug depending on the pair
• Wide feet may want half size up

Air Jordan 4 Retro Sizing

The Air Jordan 4 usually fits true to size, and this pair follows that.

I went with my true size and was actually surprised. That’s not always the case with Jordan 4s, but this one felt more forgiving.

If you have narrow, normal, or slightly wide feet, true to size should work well.

If you have really wide feet, you might still want to go up half a size.

Quick takeaway:

• True to size for most people
• More comfortable than older Jordan 4s
• Wide feet may want half size up

Air Jordan 4 Retro (Reimagined) Sizing

I’d say the Jordan 4 Reimagined fits true to size and feels more forgiving than older versions.

Nike adjusted the shape here, and you can feel it. The toe box has more space, especially around the pinky toe.

I went true to size and had no issues at all.

If you’ve struggled with Jordan 4s in the past, this one might surprise you.

If you have narrow, normal, or slightly wide feet, go true to size.

Even some wide footers can get away with true to size here, but if you want to be safe, half a size up is still an option.

Quick takeaway:

• True to size for most
• More roomy than older Jordan 4s
• Wide feet have more flexibility here

Air Jordan 4 Retro SE Craft Sizing

This one fits true to size, but like most Jordan 4s, it depends on your foot width.

I went with my usual size and it felt comfortable, which isn’t always the case with this model.

The toe box felt less aggressive than some older pairs.

If you have narrow, normal, or slightly wide feet, true to size should be fine.

If you have wider feet, I’d still recommend going up half a size just to be safe.

Quick takeaway:

• True to size for most
• More forgiving than some older Jordan 4s
• Wide feet may want half size up

Nike SB x Air Jordan 4 Retro SP Sizing

In my experience, this is one of the more comfortable Jordan 4 fits, and it runs true to size.

I went with my usual size and noticed right away that the toe box felt more generous.

The fit feels more relaxed compared to standard Jordan 4s.

If you have narrow, normal, or slightly wide feet, true to size should work perfectly.

If you have really wide feet, you could still consider half size up, but many people won’t need to.

Quick takeaway:

• True to size
• More spacious than regular Jordan 4s
• Great option if you’ve struggled with 4s before

Air Jordan 4 Military Sizing

This one is simple. Stick with your usual Air Jordan 4 size. For me, that’s true to size, and the fit felt exactly how I expected.

Air Jordan 5 Retro High Sizing

I’d say the Jordan 5 fits true to size, but it can feel slightly roomy.

I noticed a bit more space in the toe box compared to other Jordans. It was not enough to cause problems, but definitely noticeable.

If you like a bit of extra room or have wider feet, true to size works well.

If you have narrow feet or want a snug fit, you could go half a size down.

Quick takeaway:

• True to size for most
• Slightly roomy fit
• Narrow feet may size down

A Ma Maniére x Air Jordan 5 Retro SP Sizing

This one surprised me. It fits true to size, but feels more snug than expected.

I actually went half size down thinking it would run big, but it ended up feeling tighter than a standard Jordan 5.

Because of that, I’d recommend most people just stick with their true size here.

Even if you have narrow feet, true to size should still feel good.

Quick takeaway:

• True to size is the best option
• Feels snugger than typical Jordan 5s
• Avoid sizing down here

Air Jordan 6 Retro Sizing

In my experience, the Jordan 6 fits slightly big, so I prefer going half a size down.

I went down half a size and still had enough room in the toe box. The fit felt more secure and balanced.

If you have narrow or normal feet, I think half size down is the best move.

If you have wide feet or prefer a roomier fit, you can stay true to size.

Quick takeaway:

• Half size down for a better fit
• True to size if you want more room
• Slightly roomy overall

Air Jordan 7 Retro Sizing

I’d say the Jordan 7 fits snug, so sizing depends on how you like your fit.

I went half a size down and got a very secure, one-to-one fit without discomfort.

The shoe wraps your foot closely, which some people will love.

If you have narrow or normal feet and like that snug feel, you can go half a size down.

If you have wider feet or want more room, stick true to size.

Quick takeaway:

• Half size down for a snug fit
• True to size for more room
• Naturally close-fitting design

Air Jordan 8 Retro Sizing

In my experience, the Air Jordan 8 fits true to size for most people.

I went with my true size 9, and the fit felt perfect. This is a very snug, very secure, and pretty bulky sneaker. That neoprene inner bootie really wraps your foot and gives you that locked-in, one-to-one feel.

It didn’t feel long at all, and I didn’t feel like I had extra space to play with. Everything felt controlled and secure.

If you have narrow feet and you really like a tight, exact fit, you could probably get away with going half a size down.

But for most people, especially if your feet are normal or slightly wide, I’d stick with your regular size.

Quick takeaway:

• True to size for most people
• Very snug, secure, locked-in feel
• Narrow feet can try half size down

Air Jordan 11 Retro Sizing

The Air Jordan 11 fits true to size, and I’d stick with your actual measured foot size here.

I went with my true size, and the fit felt consistent with every other Jordan 11 I’ve worn. Structured, snug, and very stable on foot.

Because of the materials, especially the patent leather, the shoe doesn’t really stretch much, so what you feel out of the box is pretty much what you get.

If you have narrow or normal feet, just go true to size.

If you have wider feet, I do think going up half a size is the safer move, especially to avoid pressure along the sides.

Quick takeaway:

• True to size is the standard
• Wide feet should consider half size up
• Stick with your usual Jordan 11 size

Air Jordan 12 Retro Sizing

I’ve always felt like the Air Jordan 12 runs a little big, so I prefer going half a size down.

I went with an 8.5 instead of my usual 9, and that gave me a much better fit. Still about a finger’s width of space in the toe box, but the overall fit felt more snug and controlled.

If you go true to size, you’ll notice a bit more room, especially in length.

If you like a snug, one-to-one fit and don’t have wide feet, I’d go half a size down.

If you have wider feet or you prefer more space, true to size should still work fine.

If you’re between sizes, I’d lean toward the smaller one.

Quick takeaway:

• Runs slightly big
• Half size down for a snug fit
• True to size for wide feet or more room

Air Jordan 13 Retro Sizing

To me, the Air Jordan 13 runs a bit roomy, so I prefer going half a size down.

I went down to an 8.5, and the fit felt really nice. There’s still about a finger’s width of space in front, and while the width felt slightly snug at first, the shoe does break in nicely over time.

That snugness softens up, and the overall fit becomes more comfortable with wear.

If you like that close, one-to-one fit, half size down makes a lot of sense.

If you have wide feet or just prefer a roomier feel, you can stay true to size.

Quick takeaway:

• Slightly roomy fit
• Half size down for a snug feel
• True to size for wide feet

Air Jordan 14 Retro SE Sizing

In general, I’d say the Air Jordan 14 fits true to size.

I went with my usual size, and it felt slightly snug but in a good way. It just wraps your foot nicely without feeling too tight.

If you have narrow, normal, or slightly wide feet, true to size should work well.

If you have wider feet, I’d consider going up half a size for a bit more comfort.

Quick takeaway:

• True to size for most
• Slightly snug, secure fit
• Wide feet may want half size up

Nike Air Max Sizing

Nike Air Max 1 Sizing

I found the Nike Air Max 1 fits true to size.

This is one of the more straightforward Nike models. I wear a true size 9, and that’s exactly what works for me here.

If you have narrow, normal, or slightly wide feet, I’d stick with your regular size. If you’ve worn recent Air Max 1 releases, just keep the same size.

Quick takeaway:

• True to size
• Easy and consistent fit

Nike Air Max 1 ‘86 Big Bubble Sizing

The Big Bubble fits true to size, just like the regular Air Max 1.

The main difference I noticed is that the forefoot feels slightly wider. There’s a bit more space up front, which makes it more comfortable.

If your feet are slightly wide, this version might actually feel better than the regular Air Max 1.

If you have very wide feet, you can consider going half a size up, but most people will be fine staying true to size.

Quick takeaway:

• True to size
• Slightly wider forefoot

Nike Air Max 90 Sizing

The Nike Air Max 90 fits true to size, especially with the newer shape.

The newer shape feels consistent and reliable. It has a slightly structured feel, but nothing that feels overly tight.

If you have narrow or normal feet, true to size is the easy choice. If you have wider feet, you can still try true to size first, but going up half a size might give you a bit more comfort, depending on how sensitive you are to snug fits.

Quick takeaway:

• True to size
• Half size up for wide feet

Nike Air Max 95 OG Sizing

I’m a true size 9 with slightly wide feet, and going up to a 9.5 gave me the best fit. The shoe has that narrow, layered upper, especially through the toe box, and it can feel tight if you stay true to size.

If you have narrow or normal feet, true to size can still work, especially if you like a snug fit.

But if your feet are even slightly wide, I think half a size up makes a big difference. It gives your toes more room and makes the shoe feel much more comfortable.

If you’ve worn Air Max 95s before, nothing really changes here. The fit stays consistent across most pairs.

Quick takeaway:

• Half size up for most people
• True to size for narrow feet

Nike Air Max 97 Sizing

The Nike Air Max 97 also runs a bit snug. I usually go half a size up here.

I’m a true size 9, and I wear a 9.5 in the Air Max 97. That gives me a comfortable fit with enough toe room without feeling tight.

The upper has that sleek, narrow shape, so it naturally fits closer to your foot.

If you have narrow feet or you prefer a tight, close fit, you can stay true to size.

But if you want a bit more breathing room, especially in the toe box, half a size up is the better move.

Quick takeaway:

• Half size up
• True to size for snug fit

Nike Air Max BW OG Sizing

The Air Max BW OG fits true to size, but it does have a slightly snug feel.

I went with my regular size 9, and the fit felt good. Close, secure, but not uncomfortable.

If you have narrow, normal, or slightly wide feet, I’d stick with your usual size.

If your feet are wider, the toe box might feel a bit tight, so going up half a size can help.

Quick takeaway:

• True to size
• Half size up for wide feet

Nike Air Max 270 Sizing

The Air Max 270 runs a bit big compared to other Air Max models. In most cases, I’d go half a size down.

For reference, I wear a 9.5 in models like the Air Max 95 and 97, but the Air Max 270 fits me perfectly in a size 9.

The shoe has more room overall, especially in length, so sizing down gives a better, more secure fit.

If you have narrow or normal feet, half a size down should feel right.

If you’re worried about width or you have wider feet, you can stay true to size to avoid any tightness.

Quick takeaway:

• Half size down
• True to size for wide feet

Nike Air Max 720 Sizing

The Air Max 720 fits true to size, but it can feel a bit snug at first.

When I first tried them on, the toe box felt slightly shallow, like it was pressing down on my toes. But after wearing them for a bit, that feeling went away.

The materials soften up, and the fit becomes more comfortable.

If you have narrow, normal, or slightly wide feet, I’d stick with your regular size.

If you have very wide feet, going up half a size can give you more room.

Quick takeaway:

• True to size for most people
• Half a size up for very wide feet
• Breaks in over time

Nike Air Max Scorpion Sizing

The Air Max Scorpion runs slightly narrow, but the knit upper changes how it feels.

If you have narrow feet, true to size should feel just right.

If you have wider feet, you can still try true to size because the upper stretches a bit. But if you want more space or hate snug fits, going up half a size can help.

The fit reminds me a bit of the Vapormax.

Quick takeaway:

• True to size for most people
• Half a size up if you want more room or have wider feet

Nike Air Max DN Sizing

The Air Max DN fits true to size, but it leans slightly snug and narrow in the toe box.

I stayed true to size, and it worked fine for me. It felt secure without crossing into uncomfortable.

If you have narrow, normal, or slightly wide feet, I’d stick with your usual Nike size.

If you have really wide feet, going up half a size is the safer move, even if it means a bit of extra length.

Quick takeaway:

• True to size for most people,
• Half size up for wide feet

Nike LeBron 20 Sizing

In my experience, the LeBron 20 fits snug, so I prefer going half a size up.

I went with a 9.5, and that gave me a much more comfortable fit. About a finger’s width of space up front, and overall just more breathing room.

If you have wider feet or you plan to wear them casually, I think half a size up is the better move.

If you have narrow or normal feet and want that tight, performance-style fit, true to size can work.

For reference, I also go half a size up in models like the Kobe 5 and Kobe 6 Pro, and the same logic applies here.

Quick takeaway:

• Snug fit overall
• Half size up for comfort
• True to size for a tighter fit

Nike LeBron 20 All Star Sizing

This one still fits snug, but I noticed it felt slightly less tight than other LeBron 20 pairs.

I went half a size up again, and it worked well. There was more room in the toe box, especially lengthwise, but nothing felt sloppy. No heel slip, no instability.

The knit upper didn’t feel as restrictive as I expected.

If you have narrow or normal feet, you could probably go true to size here.

If you have wider feet or just want more comfort, I’d still recommend going up half a size.

Quick takeaway:

• Slightly less snug than standard LeBron 20
• True to size possible for narrow feet
• Half size up for comfort

UNKNWN x Nike LeBron 20 Sizing

This one fits like most LeBron 20s, so I stick with half a size up.

I went with my usual LeBron 20 size, which is half a size up, and the fit felt great, with just enough extra room.

Out of the box, the LeBron 20 can feel tight, especially if your feet are slightly wide, and I’m not always patient enough to fully break them in.

That’s why I prefer the extra space.

If you have narrow or normal feet and like a tight fit, you can go true to size.

If you have wider feet or want more comfort right away, half size up is the better option.

Quick takeaway:

• Same fit as regular LeBron 20
• Half size up for most people
• True to size for snug fit lovers

Nike Kobe Sizing

Nike Kobe 6 Protro “Reverse Grinch” Sizing

In my experience, the Kobe 6 Protro runs snug, so I prefer going half a size up, especially for casual wear.

The Kobe 6 feels amazing on foot performance-wise, but it really clamps down on your foot.

When I went true to size, I had almost zero wiggle room in the toe box, and I could feel the upper pressing down on top of my toes pretty aggressively.

So, if you’re actually hooping in these and you like that locked-in, one-to-one fit, you can get away with going true to size. But for everyday wear, I think that snugness becomes a bit too much over time.

If you have wider feet, I wouldn’t even think twice. Go half a size up. If your feet are narrow and you like that tight performance fit, true to size can still work.

If you only remember one thing, this is a snug shoe, and going up half a size makes it way more wearable.

If you’re comparing Kobes to other hoop shoes, check out my guide on how basketball shoes should fit. It’ll help you decide how snug you actually want to go.

Quick takeaway:

• Runs snug overall
• Half size up is best for casual wear
• True to size works for narrow feet or performance fit

Nike Dunk Sizing

Nike Dunk Low Sizing

The Nike Dunk Low fits true to size. This one is simple and very consistent.

I wear a size 9, and the fit feels spot on. Even with slightly wider feet, I had no issues at all.

The shape is neither too narrow nor too roomy.

If you’ve worn Dunks before, just stick with your usual size. Nothing really changes across most pairs.

If you have very wide feet, you might consider going up half a size, but most people won’t need to.

Quick takeaway:

• True to size
• Very consistent fit

Nike Women’s Dunk Low Sizing

The Women’s Dunk Low fits true to size, even if you’re buying in men’s sizing.

You just need to convert your size correctly. In general, you go up 1.5 sizes from your men’s size. So if you wear a men’s 9, you’ll go for a women’s 10.5.

What surprised me here is the fit. Even though this is a women’s release, it actually felt slightly more forgiving than some men’s Dunks I’ve worn.

I think the suede feels softer and more broken-in, so your foot doesn’t feel as boxed in.

If you have narrow, normal, or slightly wide feet, I’d stick true to size after converting.

If you have really wide feet, you can consider going up half a size for more comfort.

Quick takeaway:

• True to size (after conversion) for most people
• Half a size up if you have wide feet.

Nike Dunk Low Premium Sizing

The Nike Dunk Low Premium fits true to size, but it does run slightly short.

I went with my usual size 9, and while the width felt fine, the length felt a bit tighter than a standard Dunk. I could feel my toe getting close to the front, especially when my foot shifted forward.

If you lace them tight, it’s manageable. But if you like a looser lace style, that’s when you’ll notice the shorter feel more.

If you’re between sizes, I’d definitely go up half a size here.

If you like a snug, one-to-one fit, true to size can still work, but just expect it to feel a bit shorter than usual.

Quick takeaway:

• True to size for a snug fit
• Half a size up if you want more toe room or you’re between sizes.

Nike Dunk Low Premium “Tweed / Corduroy” Sizing

This pair fits like a standard Dunk Low.

I’d go true to size here without overthinking it.

The length feels right, and the overall shape is consistent with most Nike Sportswear Dunks.

If you have narrow, normal, or slightly wide feet, your regular size should work fine.

If you have wider feet, you might feel some tightness around the toe box, so going up half a size can help.

Quick takeaway:

• True to size for most people
• Half a size up for wide feet

Nike Dunk Low Premium Co.JP Sizing

The Co.JP Dunks fit just like most regular Dunk Lows.

I went true to size, and the fit felt exactly how I expected.

If you already know your Dunk size, just stick with it here. Nothing really changes.

Quick takeaway:

• Go true to size

Nike Dunk Low Retro SE Sizing

The Dunk Low Retro SE fits true to size, but it leans slightly snug.

On foot, it gives that close, one-to-one fit that a lot of people like in Dunks.

If you have narrow or normal feet, I’d stay true to size without hesitation.

If you have wider feet, it might feel a bit tight, but not always enough to force you to size up.

If your feet are really wide or you hate snug fits, then going up half a size is the safer move.

Quick takeaway:

• True to size for most people
• Half a size up if you have wide feet or want more room.

Nike SB Dunk Low Sizing

The Nike SB Dunk Low runs snug. I almost always go half a size up here.

The extra padding around the tongue and collar makes a big difference. It fills up the shoe more and creates a tighter fit compared to regular Dunks.

When I go true to size, it feels tight, especially along the sides of my foot.

Going up half a size gives me the space I need without making the shoe feel sloppy.

If you have narrow feet and you like a tight, locked-in fit, true to size can still work.

But for most people, especially if you have average or wide feet, half a size up just feels better.

Quick takeaway:

• Go half a size up in SB Dunk Lows.

Nike SB Dunk Low Pro Sizing

The SB Dunk Low Pro fits very similar to the regular SB Dunk, but it can feel slightly roomier depending on the materials.

I still prefer going half a size up, especially because of the padded tongue and my slightly wider feet.

That said, this version felt just a touch more forgiving than some other SB Dunks I’ve worn.

If you like a snug fit and you have narrow feet, you can go true to size.

If you want more comfort or have wider feet, half a size up is still the better move.

Quick takeaway:

• Half a size up for most people
• True to size if you want a snug fit.

Nike SB Dunk Low Pro Premium Sizing

The SB Dunk Low Pro Premium fits like most SB Dunks. Slightly snug with extra padding.

I’ve tried them true to size, and they fit, but they definitely feel tight.

Going up half a size gives a much more comfortable fit, especially over longer wear.

If you have narrow or normal feet and like that close, snug feel, you can stay true to size.

If you have wider feet or just want more room, half a size up is the way to go.

Quick takeaway:

• Half a size up for most comfort
• True to size only if you prefer a snug fit.

Born X Raised x Nike SB Dunk Low Pro QS Sizing

This pair runs snug, even for an SB Dunk. At a minimum, I’d go half a size up, and some people might even want to go a full size up.

I went half a size up from my true size, and it still felt tight. The toe box didn’t feel very roomy, and I only had about a finger’s width up front.

I think the extra padding plays a big role here. The collar and overall build feel more stuffed than usual, which makes the shoe feel more compact on foot.

If you like a snug fit, half a size up should still work.

If you prefer a bit more space or you have wider feet, going a full size up is not a crazy idea here.

Quick takeaway:

• At least half a size up
• Possibly a full size up if you want more room.

Run The Jewels x Nike SB Dunk Low Pro Sizing

This one actually fits a bit more forgiving than a typical SB Dunk.

I still went half a size up, but the shoe felt slightly longer and less tight than what I’m used to with SBs.

There was a bit more space in the toe box, and the width didn’t feel as restrictive.

If you have narrow or normal feet and you like a snug fit, you could go true to size here.

If you have wider feet or you just want that extra comfort, half a size up is still the safer move.

Quick takeaway:

• Half a size up is safe
• True to size can work if you like a snug fit.

Fly Streetwear x Nike SB Dunk Low Pro Sizing

This fits like a classic SB Dunk.

I personally go half a size up because of the padded tongue and overall snug feel.

If I go true to size, it feels a bit too tight, especially when I lace them up properly.

That said, if you wear your laces loose and like a more relaxed fit, true to size can work.

If you tie your laces and want comfort, half a size up makes more sense.

Quick takeaway:

• Half a size up for most people
• True to size if you like a loose, relaxed fit

Supreme x Nike SB Dunk Low OG QS “Rammellzee” Sizing

This pair fits like most SB Dunks.

I go half a size up, and that’s what feels best for me, especially with slightly wider feet.

If you have narrow or normal feet and you like a snug fit, true to size can work.

If you want more room or you have wider feet, half a size up is the better move.

Nothing unusual here.

Quick takeaway:

• Stick with your usual SB Dunk size, which for most people is half a size up.

HUF x Nike SB Dunk Low OG Sizing

This one runs narrow, even compared to other SB Dunks.

I went half a size up, and I could still feel some pressure along the sides of my toes.

If I had gone true to size, it would have been way too tight.

The elastic tongue setup adds to that locked-in feel, which makes the shoe feel even more snug.

Quick takeaway:

• Definitely go half a size up here, especially if you have anything other than narrow feet.

Yuto Horigome x Nike SB Dunk Low Pro QS Sizing

This pair fits close to a standard SB Dunk, even with the slightly thinner tongue.

If you have narrow or normal feet, you can go true to size for a snug fit.

If you have wider feet or you don’t like pressure around the forefoot, half a size up is the better option.

You can break them in over time, but out of the box, they still feel on the snug side.

Quick takeaway:

• True to size for a snug fit
• Half a size up for comfort.

Concepts x Nike SB Dunk Low OG QS Sizing

This one fits like most SB Dunks.

I’d go half a size up, just like I normally do with SBs. Nothing really changes here in terms of fit.

Quick takeaway:

• Half a size up

Nike Air Foamposite 1 Sizing

The Air Foamposite 1 fits true to size, but it starts off snug before molding to your foot.

The Foamposite is a very different kind of fit compared to most Nike sneakers.

Out of the box, it can feel stiff and tight, but that’s part of the design. Over time, the upper softens and shapes itself to your foot, and that’s when the fit really starts to shine.

I did notice a bit of heel slippage at first, but once I laced the shoe all the way up, that problem completely disappeared.

After that, the lockdown felt solid, especially with how the lacing system pulls your foot into the shoe.

If you have normal or slightly wide feet, I’d stick true to size and let the shoe break in. If you go up, you risk losing that molded, secure feel that makes this shoe special.

Quick takeaway:

• True to size overall
• Starts snug but molds to your foot
• Avoid sizing up unless you want a looser fit

Nike Zoom Vomero 5 Sizing

In my experience, the Nike Zoom Vomero 5 fits true to size, with a nicely balanced fit.

What I like about this one is how it locks in the midfoot while still giving your toes a bit of breathing room. It doesn’t feel overly snug or overly roomy. It sits right in the middle.

For the women’s “Oatmeal” release, you do need to convert sizing by going up 1.5 sizes to get your men’s equivalent. Once you do that, the fit feels spot on.

If you have narrow, normal, or slightly wide feet, I’d stick true to size.

Quick takeaway:

• True to size
• Balanced fit, not too snug or loose
• Women’s pairs require +1.5 size conversion

Nike Air Vapormax Sizing

I’d say the Nike Vapormax fits true to size, but it still leans narrow, especially through the midfoot.

I went true to size, and it felt good overall. Compared to older Vapormax models, this one does feel slightly wider in the forefoot, which helps a bit if your feet are slightly wide.

But I still wouldn’t call it wide-foot friendly.

This is meant to feel like a sock on your foot, so sizing up too much can make it feel sloppy and awkward.

If you have narrow or normal feet, I’d stay true to size.

If you have wider feet, you can try going half a size up, but just know it might affect that snug, sock-like feel.

Quick takeaway:

• True to size for most
• Slightly narrow, especially midfoot
• Wide feet can try half size up carefully

Nike Presto Sizing

Nike Air Presto (OG) Sizing

The Nike Air Presto (OG) runs big, and the sizing can feel confusing because of the T-shirt system.

This is one of the strangest Nike fits out there. Instead of regular sizing, you get XS, S, M, L, and each size covers a wide range of foot lengths.

When I first tried a Medium, it honestly felt huge. I had way too much space, almost like I was swimming in the shoe.

The idea behind the Presto was to create that barefoot, sock-like feel, similar to the Huarache concept. But because each size stretches across multiple foot sizes, it doesn’t feel as precise as a typical Nike sneaker.

So if you’re new to Prestos, this is not a shoe I’d buy blindly online. Definitely try it on in-store.

Quick takeaway:

• Runs big
• T-shirt sizing makes it tricky
• Try before you buy if possible

Off-White x Nike Air Presto Sizing

The Off-White x Nike Air Presto fits true to size if you can get your exact size, but things get tricky if you’re between sizes.

When you land your true size, the fit is actually great. The upper feels supportive without squeezing too much, and once your foot is in, the shoe opens up and gives you a roomy, comfortable feel.

But here’s the catch. These only come in full sizes.

So if you’re a half-size wearer, you don’t really get a perfect option. Normally, I’d say go down for snug or up for comfort, but with this pair, availability matters just as much as fit.

I’ve tried pairs a full size up, and they were still wearable. Not perfect, but definitely manageable. Going down can also work if you loosen the laces, since Prestos tend to stretch a bit over time.

Keep in mind that the collar is tight, and getting your foot in can feel like a struggle at first. But once you’re in, the fit feels much better.

Quick takeaway:

• True to size if you can
• Full sizes only
• Sizing flexibility thanks to stretch

Acronym x Nike Air Presto Mid Sizing

The Acronym x Nike Air Presto Mid fits true to size, but it runs long and slightly narrow.

Like other Prestos, this one only comes in full sizes, so if you’re between sizes, you’ll need to pick the closest option.

I went true to size, and the fit worked, but I definitely noticed extra length in the toe box. At the same time, the width felt more snug and secure compared to the OG Presto.

What really stood out here is the lockdown. Once you zip everything up and tighten the laces, your heel feels locked in, almost glued in place.

That’s very different from the softer, stretchier feel of regular Prestos.

I wouldn’t size down, though. Even if it runs long, going smaller would make it too tight.

Quick takeaway:

• True to size
• Runs long but slightly narrow
• Strong lockdown feel

Nike Presto React Sizing

In my experience, the Nike Presto React fits true to size, and it’s by far the easiest Presto to size.

After dealing with the OG version, this one feels much more straightforward. I went true to size, and the fit felt right immediately.

That said, there are stitched areas and overlays that can feel slightly restrictive if you have wide feet or a higher arch.

It’s not uncomfortable, but it’s not as forgiving as the original stretchy Presto upper.

If you have narrow or normal feet, true to size works perfectly. If you have wider feet or prefer more room, going up half a size can help.

Quick takeaway:

• True to size for most people
• Half size up for wide feet
• Much easier fit than OG Presto

Nike Rejuven8 Sizing

Nike ReactX Rejuven8 Clog Sizing

I found the Reactx Rejuven8 clog fits true to size, but it can feel slightly short in the toe box.

Nike only offers whole sizes here, so if you rely on half sizes, you’ll need to make a decision.

I’m a true size 9, and the size 9 felt almost perfect right away.

Width-wise, it was great. But length-wise, my toes were sitting pretty close to the front. Not painful, but close enough that I noticed it.

When I tried a size 10, the extra length helped, but I lost that secure, locked-in feel. The heel felt looser, and the overall fit just wasn’t as dialed in.

So here’s how I’d break it down.

If you wear a whole size, I’d stay true to size if you like a snug, secure fit. That’s where the clog feels the most stable and natural.

If you’re between sizes, I think going up to the next whole size makes more sense. The extra length helps avoid that “toes at the edge” feeling, even if the fit becomes a bit more relaxed.

For wide feet, I’d lean toward sizing up as well. The width is forgiving, but the material still hugs your foot once you’re in, so the extra space can help.

Quick takeaway:

• True to size for a snug, secure fit
• Half sizes should go up to the next whole size
• Slightly short in length, especially up front
• Size up if you want more room or have wider feet

Nike ReactX Rejuven8 Slide Sizing

I’d say the Rejuven8 slides fit true to size, and they feel much easier to get right than the clogs.

I went with my usual size 9, and everything felt right immediately. The length was spot on, my heel sat perfectly, and my toes didn’t feel pushed forward.

Compared to the clogs, these feel more forgiving because the open design gives your foot more freedom, so you don’t get that same “tight entry” or structured feel.

That said, the strap across the top does feel a bit snug at first. Personally, I like that. It keeps the slide feeling secure instead of loose and sloppy when you walk.

If you have narrow, normal, or slightly wide feet, I’d just stick with your true size here. It works.

If you have wider feet or you just want more space, you could go up, but I don’t think most people need to.

Quick takeaway:

• True to size for most people
• More forgiving than the clog version
• Slightly snug strap at first, but secure on foot
• Wide feet can consider sizing up, but not required

Nike Mind Sizing

Nike Mind 001 sizing

In my experience, the Nike Mind 001 runs small, so I’d go up one full size for most people.

This one is tricky because it only comes in full sizes, and the fit doesn’t feel very forgiving. When I tried my true size, it felt very exact.

My toes were right at the edge, and my heel didn’t have much room, which made walking feel a bit unstable.

Going up a full size made a big difference. There was more space, my heel sat better, and the overall feel was much more comfortable, even if it was slightly less locked in.

If you have narrow feet and plan to wear them barefoot, true to size can work. But for most people, especially with socks, sizing up just feels better.

Quick takeaway:

• Runs small
• Go up one full size for comfort
• True size only for snug, barefoot wear

If you’re comparing these to other comfort slides, especially something softer and more minimal, check out my Yeezy Slides sizing guide. The fit is very different, and it’s one of those cases where your Nike size doesn’t translate directly.

Nike Mind 002 sizing

The Nike Mind 002 fits true to size and feels much easier to get right.

The big difference is that this one comes in half sizes, and the fit is more forgiving overall. I went with my usual size, and it felt balanced right away.

Compared to the 001, this feels roomier and more natural on foot, while still giving you that snug, secure feel.

If you have narrow or normal feet, stick with your usual size. If you have wider feet or want more room, you can go up half a size.

Quick takeaway:

• True to size for most people
• More forgiving than the Mind 001
• Half size up for wide feet or extra room

Nike Cortez Sizing

The Nike Cortez runs narrow, so I’d avoid going down a size and consider going up half a size if you have wider feet.

This is a classic silhouette with that slim, close-on-foot shape. It looks clean on foot, but that narrow build can feel restrictive, especially in the forefoot.

If you have narrow or average feet, you can stick true to size and it should feel fine. But if your feet are even slightly wide, you’ll probably notice that tightness pretty quickly.

Now, the Sacai Zoom Cortez 4.0 is a different story. That version feels more forgiving and slightly roomier, so even wide-footers can usually go true to size there.

Quick takeaway:

• Classic Cortez runs narrow
• True to size for narrow/average feet
• Half size up for wide feet

Nike Air Huarache Sizing

I found that the Nike Air Huarache runs snug, so I’d recommend going at least half a size up.

This shoe has that sock-like neoprene upper, and it really hugs your foot. On top of that, the structure of the shoe pushes your foot forward, which makes the toe box feel even tighter.

Even going up half a size, my toes still felt fairly close to the edge of the shoe. That’s just how the Huarache fits.

If you like that snug, locked-in feel, half size up will be perfect. If you want more room or you have wider feet, you could even consider going a full size up.

Quick takeaway:

• Runs snug and sock-like
• Half size up is standard
• Full size up for wide feet or extra room

Stussy x Nike Air Huarache LE Sizing

In my experience, the Stüssy x Nike Air Huarache LE runs snug, so I’d recommend going at least half a size up.

Like the regular Huarache, this collab really hugs your foot. Because of the design, especially that external heel counter, your foot gets pushed forward, which makes the toe box feel tighter than you’d expect.

When I went up half a size, I still had under a finger’s width of space in front of my toes, which tells you everything about how this shoe fits.

It’s very close, very secure, and very much that sock-like Huarache feel.

If you go true to size and your feet are even slightly wide, it’s going to feel extremely tight, almost like a glove. Some people like that, but for most, it’s a bit too restrictive.

If you prefer a snug, locked-in fit, half a size up is perfect. If you want more breathing room or you have wider feet, I’d even consider going a full size up.

Quick takeaway:

• Runs snug and sock-like
• Half size up is the safe choice
• Full size up for wide feet or extra room

Nike P-6000 Sizing

The Nike P-6000 fits true to size, and it feels surprisingly comfortable even for wider feet.

The fit feels balanced, not too tight, not too loose, and the midfoot has enough give to avoid that narrow feeling you get in some Nike runners.

Even if you’ve had issues with models like the Vomero feeling tight, I don’t think you’ll run into that here.

If you have narrow, normal, or even slightly wide feet, I’d stick true to size without overthinking it.

Quick takeaway:

• True to size
• Comfortable midfoot
• Works for most foot types

Nike Pegasus Sizing

The Nike Pegasus fits true to size, just like most Pegasus models.

This is one of the most consistent lines when it comes to Nike sizing. When you put them on, nothing feels surprising. The fit is balanced and easy to wear.

If you’ve worn Pegasus before, you already know what to expect. If not, you can confidently go with your regular Nike size.

Quick takeaway:

• True to size
• Consistent Nike fit
• Safe choice for most people

Nike Invincible Sizing

The Nike Invincible fits true to size, with a standard width.

This is a max-cushion running shoe, but unlike some bulky models, it doesn’t feel overly wide or sloppy. The fit feels secure while still giving you enough comfort for long wear.

If you’ve worn other Nike running shoes, this should feel very familiar.

Nike Vaporfly 3 Sizing

The Nike Vaporfly 3 fits true to size, but it leans narrow, especially in the forefoot.

This is a performance-focused running shoe, so the fit is naturally more streamlined. When I wore it, I could feel that snugness, especially toward the front of the shoe.

If you have narrow feet, true to size should feel great. If you have wider feet, this is where things get tricky.

You might be able to go up half a size, but honestly, I’d recommend trying them on first if possible, because the shape itself is narrow.

Quick takeaway:

• True to size
• Narrow forefoot
• Wide feet should try before buying or size up

Nike Ja 1 “Day One” Sizing

In my experience, the Nike Ja 1 runs narrow, so I’d recommend going half a size up, especially for wider feet.

I went up to a 9.5, and that was the right move for me. Even then, the shoe still felt snug, especially around the area above the laces.

Even when I loosened the laces completely, I could feel pressure across the top and sides of my foot. So I can only imagine how tight it would have been if I stayed true to size.

If you have narrow or normal feet and want that tight performance fit, true to size can work.

But if you have wider feet, or if you plan on playing in them with thicker socks like Nike Elite socks, I’d definitely go half a size up.

Quick takeaway:

• Runs narrow
• Half size up for comfort
• True to size only for narrow feet

Nike V2K Run Sizing

The Nike V2K Run fits slightly snug, so I’d recommend going half a size up if you’re buying them as a man.

Since this is technically a women’s release, the shape leans a bit narrower than your typical Nike running-style sneaker.

When I tried them in my true size, they felt tighter than something like the Vomero 5, especially through the midfoot.

For women, I think sticking true to size makes the most sense. The fit feels consistent with other Nike lifestyle runners. But for men converting sizes, that extra half size really helps balance out the narrower shape.

If you have wider feet, I’d go up half a size. If your feet are narrow, you might still be fine true to size, but it will feel closer on foot.

Quick takeaway:

• Slightly snug fit overall
• Men should go half size up
• Women can stay true to size

Nike Air Monarch IV Sizing

The Nike Air Monarch IV fits a bit big, so I prefer going half a size down.

This is a very chunky, old-school trainer, and it comes with a lot of internal volume. When I tried my usual size, it felt roomy enough that sizing down made more sense.

The good thing is, if you have wide feet, this shoe is very forgiving. It has that wide, supportive platform that doesn’t squeeze your foot.

If you like a snug fit, go half a size down. If you have wide feet or you prefer more room, true to size still works.

Quick takeaway:

• Runs slightly big
• Half size down for snug fit
• Wide-foot friendly

Nike Air Ship PE SP Sizing

I’d say the Nike Air Ship fits true to size, but it feels slightly more snug than a Jordan 1.

I went with my true size 9, and the fit was good overall, but I could feel a bit more pressure along the width.

It’s not overly tight, but you do notice that it hugs your foot a bit more.

If you have narrow, normal, or slightly wide feet, true to size should still work fine.

If you have wider feet, I’d consider going up half a size just to avoid that tight feeling.

Quick takeaway:

• True to size for most
• Slightly snugger than Jordan 1
• Wide feet may want half size up

Nike NOCTA Glide Sizing

In my experience, the NOCTA Glide fits a bit long, so going half a size down works best.

This one is tricky. Length-wise, it definitely runs bigger, which is why I went down half a size. That helped balance things out, but I still noticed some heel slippage.

The width, however, feels fine. Even if you have slightly wider feet, going down half a size shouldn’t cause any major issues in the forefoot.

If you stay true to size, the extra length can make the shoe feel loose and unstable, especially in the heel.

Quick takeaway:

• Runs long overall
• Half size down recommended
• Expect some heel slippage

Nike Blazer Mid ’77 Sizing

The Blazer Mid ’77 fits true to size, but it feels a bit snug through the width.

The Blazer fits pretty straightforward in length, but the upper can feel a little stiff and tight at first.

When I wore my true size, the length was perfect, but I did feel that snugness around the sides of my foot.

The good news is the material does break in over time, so it becomes more comfortable the more you wear it.

If you have narrow or average feet, I’d stick true to size. If you have wider feet, going up half a size will give you that extra breathing room.

Quick takeaway:

• True to size in length
• Slightly snug width
• Half size up for wide feet

Nike React Element 87 Sizing

The React Element 87 fits true to size, but it runs slightly long and narrow.

When I went true to size, I noticed a bit of extra space in the toe box, but the width felt just right. That balance actually worked well for me.

If you have very narrow feet, you might be able to go down half a size, but for most people, true to size is the safest and most consistent option.

If you have wider feet, I definitely wouldn’t size down. The narrow shape could start to feel restrictive.

Quick takeaway:

• True to size overall
• Slightly long and narrow
• Only size down if you have narrow feet

Nike Cosmic Unity Sizing

The Cosmic Unity fits true to size, but it gives you a snug, one-to-one feel.

The Cosmic Unity really wraps around your foot. I personally liked that fit, especially for casual wear, but I can see why some people might find it a bit too tight.

If you like that close, performance-style fit, true to size works perfectly. If you prefer a bit more room or you have wider feet, going up half a size will make it more comfortable.

Quick takeaway:

• True to size overall
• Snug, close fit
• Half size up for more comfort or wider feet

Nike Air More Uptempo Sizing

The Nike Air More Uptempo fits true to size, but it leans slightly big.

This is a bulky, statement sneaker, and that extra volume does translate into a bit more room on foot. When I went true to size, the fit was totally fine, but I did feel like I could’ve gone half a size down for a more locked-in feel.

If you’re between sizes, I’d definitely lean toward the smaller size. If you like a snug, secure fit, going half a size down makes more sense here.

That said, if you prefer a bit of space or you just want an easy everyday fit, true to size still works.

Quick takeaway:

• True to size, but slightly roomy
• Half size down for a more locked-in fit
• Between sizes, go smaller

Nike Mac Attack QS SP Sizing

The Nike Mac Attack fits true to size in length, but it runs a bit narrow.

Right away, I noticed the footbed feels tighter than expected. The length is correct, but the width feels restricted, especially around the ball of your foot.

If you have narrow or average feet, I think you’ll be fine sticking true to size. But if your feet are even slightly wide, you’ll probably feel that pressure pretty quickly.

For wide feet, I’d go up half a size to avoid that cramped feeling.

Quick takeaway:

• True to size in length
• Narrow footbed
• Half size up for wide feet

Nike Air Zoom Generation Sizing

The Nike Air Zoom Generation fits true to size, with a slightly snug feel at first.

When I tried them on, the length felt spot on, with just over a finger’s width of space in the toe box. The width felt a bit snug initially, but once I loosened the laces, it became much more comfortable.

If you have narrow, normal, or slightly wide feet, I’d stick true to size. If you have really wide feet, you might feel that tightness more and want to go up half a size.

Quick takeaway:

• True to size overall
• Slightly snug at first
• Half size up for wide feet

Nike Air Trainer 1 Sizing

The Nike Air Trainer 1 fits true to size, but it can feel snug around the midfoot.

This is especially noticeable around the lace area, where the shoe tends to tighten up more than expected. Even with some adjustment, it still leans toward a snug fit.

If you have narrow or average feet, true to size should feel solid. If your feet are slightly wide, you might still get away with it, but it will feel close.

For really wide feet, I’d go up half a size to avoid pressure.

Quick takeaway:

• True to size overall
• Snug midfoot fit
• Half size up for wide feet

CPFM x Nike Air Flea 2 Sizing

The CPFM Air Flea 2 fits true to size, despite how oversized it looks.

It looks like it should fit huge, but once you actually put it on, the sizing feels surprisingly normal.

That said, I did notice a bit of snugness through the midfoot. It’s not extreme, but it’s there.

If you have narrow or average feet, true to size should work perfectly. If you have wider feet, go up half a size, and you will be more comfortable.

Quick takeaway:

• True to size overall
• Slight midfoot snugness
• Half size up for wide feet

Final Thoughts

If you’ve made it this far, you’ve probably noticed one thing… Nike sizing isn’t as simple as “always go true to size.”

Some models are easy. Others depend heavily on shape, materials, and how you like your shoes to feel on foot.

In general, I’d say most Nike sneakers do run true to size. But there are clear patterns you can rely on.

Retro models like Air Max 1, Air Max 90, and Dunk Low are very consistent. You can usually stick with your regular size and not overthink it.

Narrower models like Air Max 95, Air Max 97, Kobe, and SB Dunks tend to feel more snug. That’s where going up half a size makes a big difference, especially if your feet are even slightly wide.

Then you’ve got roomier models like Air Force 1 or Air Max 270, where sizing down half a size often gives a better fit.

And finally, there are the outliers like the Mind 001 or Presto OG, where sizing really depends on how the shoe is built. Those are the ones you don’t want to guess on if you can avoid it.

If you ask me, the easiest way to approach Nike sizing is this:

• Start with your true size, then adjust based on the model and your foot shape.
• If you have wide feet, you’ll often be more comfortable going up half a size in snug models.
• If you have narrow feet or prefer a tighter fit, you can sometimes size down in roomier silhouettes.

At the end of the day, it comes down to how you want your shoes to feel. Some people like that snug, one-to-one fit. Others want a bit more space to move.

If you’re still unsure about your fit, drop a comment below and tell me the exact model you’re looking at, your usual Nike size, and how your feet are shaped.

I’ll help you figure it out.

If you already own a pair, feel free to share your experience too.

And if there’s a sneaker I didn’t cover, let me know. I’ll add it to the guide 👍
