Nike Presto sizing has always been a little weird.
The shoe was literally designed to feel like a T-shirt for your foot, so Nike decided to size it the same way: XS, S, M, L… you get the idea.
It sounded cool at first, but once you actually try to pick a size, things get confusing fast. One model uses the old T-shirt system, another uses regular numbers, and some pairs even switch charts over the years.
No wonder everyone ends up Googling a Presto size chart before buying a pair.
In this guide, I walk you through everything you need to know about Presto sizing.
I cover the history behind the sizing, how the different models fit, what you should look out for if you have wide feet, how to measure your feet properly at home, and the sizing quirks of Off-White, Acronym, and the OG Prestos.
Sound interesting?
Let’s dive right into it…
Nike Presto Sizing Guide
History of Presto Sizing
When people talk about weird Nike sizing, the Presto always shows up in the conversation, and there’s a reason for that.
The Air Presto was built to feel like a T-shirt for your foot, and Nike literally sized it like one. Small, medium, large, extra large… that was the whole idea.
The stretchy neoprene upper and the heel notch were supposed to let the shoe adapt to a range of foot shapes the same way a T-shirt adapts to your body.
Back in the day, Nike used the original T-shirt sizing chart for Prestos. Something like:
- S fit US men’s 9–10
- M fit US men’s 10–11
- L fit US men’s 11–12
- XL fit US men’s 12–13
- XXL fit US men’s 13–14
That’s how it stayed for years. But then things got messy.
When I was trying to figure out what size to get, I went with a Small, because Nike listed it as fitting a men’s 9–10 at the time.
That made sense. But right after release day, when the L hit me and I checked the SNKRS app again, Nike had changed the sizing chart.
My “Small” suddenly went from US 9–10 to US 7–9. Every size above and below shifted too. So the entire chart moved, and anyone who relied on the old numbers was left confused.
Fast forward to today, after doing my own research, the pattern looked like this:
Nike used the classic T-shirt system up until around 2014–2015, then pivoted to a more standard numbered sizing system for some releases.
Not all, though. That’s where things get even trickier. Some modern Prestos still use the old S/M/L format. Some use standard shoe numbers. And then certain special editions, like the Acronym Prestos, go right back to the T-shirt formula.
So today, Presto sizing isn’t one single system. It depends on the model, the year, and sometimes the specific release.
You have Prestos that follow the 3XS through 3XL alpha chart. You have Prestos that use normal numeric sizing. And you have Prestos that bounce between both.
Now, Prestos and Foamposites don’t fit the same way, but they share that “unique fit you need to understand before buying” vibe, so I broke down everything in my latest Foamposites sizing guide.
Here’s the current Nike Presto size chart:

Here’s what that means for you:
Always double-check the sizing system before you buy. If it uses S/M/L, use Nike’s conversion chart, not whatever old screenshot you remember from years ago.
If it uses numeric sizing, treat it like a regular shoe. And because the Presto upper stretches and adapts more than most Nike models, some people even order two sizes when returns are easy, just to be safe.

Nike Air Presto (OG) Sizing

The OG Nike Air Presto is honestly one of the weirdest sizing experiences Nike has ever created. I’m not kidding.
These run big, and the sizing system is so strange that it kept me away from them for years. When I first tried a size 9, I was basically swimming in it.
There was way too much room in there, and that’s when I understood why some people love Prestos and others get confused by them.
Nike brought them back using the original T-shirt sizing: XS, S, M, L. And that’s where things get tricky. I put on a Medium and it felt like I had two full inches of empty space.
Prestos were meant to mimic a barefoot feel, kind of like an evolution from the Huarache idea, but the way the sizes stretch across multiple foot lengths can throw you off if you’ve never worn them before.
Honestly, this is one of those shoes you do not want to buy blind. If you can go in store, do it. Try them on.
Prestos are too unpredictable to trust an online size chart, unless you’re someone who already knows which T-shirt size works for your foot. If you’re new to Prestos, try first and buy second.

Off-White x Nike Air Presto Sizing

The Off-White Presto is one of those shoes that makes you excited and annoyed at the same time. The design is amazing, the comfort is classic Presto comfort, but the sizing… the sizing can make you want to pull your hair out.
When you’re lucky enough to be a perfect whole size, life is easy. The shoe fits true to size and the comfort is everything people say it is.
The upper feels supportive without squeezing too hard, the midsole feels soft, and once you get past the collar, the shoe opens up and gives you a nice roomy toe box.
Honestly, when you land your true size, the Off-White Presto fits like a perfect Presto should.
Things get complicated when you’re between sizes. The Off-White Prestos only come in full sizes. So if you’re a half-size person, you’re already in tricky territory before you even get the shoe on your foot.
Normally, I’d say something like, “go down if you want a snug fit, go up if you want more room.” But because the Off-White Prestos are so hard to get and sometimes insanely priced, the honest advice is this: get whichever size you can afford or whichever size is actually available.
I’ve tried pairs that were a full size up and they were still wearable. Not ideal, not perfect, but definitely not a disaster.
And if you go half-size down, you can loosen the laces and make it work. Prestos stretch more than most Nike shoes, so they give you some leeway.
One thing that catches a lot of people off guard is how hard these are to slide into. The collar area doesn’t have much give, so the first few tries feel like you’re fighting the shoe.
But once your foot is inside, the fit settles in and you forget about the entry struggle.

Acronym x Nike Air Presto Mid Sizing

The Acronym Prestos only come in full sizes too, which already makes things interesting if you’re a half-size person.
I’m a true size 9 slightly on the wider side, so I grabbed these in a 9. They fit, but they definitely run long and slightly narrow. Width-wise, they hugged my foot perfectly, but length-wise, the size 9 had more room than I expected.
I wouldn’t go down to an 8.5, though. That would be way too tight. Just something to keep in mind: expect a bit more space in the toe box compared to the classic Presto.
Comfort is great, though. What surprised me most is the lockdown. Once you zip up both zippers and tighten the laces, your heel feels glued into place.
For a Presto, that kind of lockdown feels unique, especially if you’re used to the softer, stretchier feel of the OG version.

Nike Presto React Sizing

The Presto React is the one that finally made me say “thank you.” These actually fit true to size, and after dealing with OG Prestos where I was drowning in my normal size, this felt like a breath of fresh air.
If you’re thinking about grabbing a pair, going true to size works for most people.
Wide footers might want to go up half a size.
The upper has some top stitching and structural pieces that can feel restrictive if you have a high arch or wide forefoot. It’s not painful, but it can feel a bit tight.
As always, if you can try these in store, you should. But compared to the other Presto models, this one is much easier to get right.

How to Measure Your Feet for Nike Air Prestos
Air Prestos are tricky because the whole XS, S, M, L system does not match the normal Nike sizing chart.
Try Them In Store
Honestly, the best way to get your Nike Presto sizing right is to try the shoe in store.
Prestos feel different from one version to another, and no size chart can tell you exactly how the collar, the cage, or the toe room will feel on your foot.
When you try them in person, you know right away if you sit closer to a Small or a Medium or if the shoe runs too long for you.

Get Measured by a Professional
If you can’t find the exact Presto model you want, the next best thing is to get measured by a professional in store.
A trained fitter knows how to read a Brannock device and they can check your length, width, arch height, and any pressure points.
I trust a professional measurement more than any online chart because it shows you how your foot actually behaves inside a shoe.
Here is how to measure your feet with a Brannock device:

If you don’t have access to a Brannock device, here’s how to measure your feet at home:
Measure Your Feet at Home
What you need:
- A sheet of paper
- A pen
- A wall
- A ruler or tape measure
Steps:
- Place the paper flat on the floor and push it against the wall.
- Stand on the paper with your heel touching the wall.
- Keep your weight on your foot so it spreads naturally.
- Mark the tip of your longest toe.
- Step off and measure the distance from the wall to your mark.
- Repeat with the other foot and use the bigger number because that is your true measurement.
- Compare Your Measurement to the Presto size chart below

This gives you the actual length you should compare to the Presto size chart and it helps you understand if you fall closer to a Small or a Medium.
Test the Fit In Person if You Can
What I check:
- My toes should not swim in the front
- The midfoot cage should feel snug but not painful
- My heel should feel secure when I walk
- No pressure on the top of my foot
- No sliding inside the shoe
Tips That Actually Help
- Try them in the afternoon because your feet get slightly bigger later in the day
- Wear the socks you will use with your Prestos
- If you are between two Presto sizes, go with the smaller one for the OG and go with the bigger one for the Acronym Mids
- Wide footers should be careful with the Acronym model because it runs narrow

Final Thoughts
I always tell people that Nike Presto sizing is one of the strangest but coolest sizing experiences in the whole Nike lineup.
You never know what you’re dealing with until you try the specific model on. The OG runs big, the Acronym runs long and narrow, and the React finally gives you something simple and true to size.
If you can try Prestos in store, do it. My first pair felt like a gamble because I bought them online and I ended up swimming in them.
You don’t need to repeat that mistake. Once you figure out your fit, the shoe becomes way more fun.
Now, what’s your experience with Presto sizing? Did you go true to size, up, or down?
