The Nike P-6000 has become one of the best alternatives to the Nike Vomero 5.
Both have that early-2000s running-shoe look, both are comfortable enough for everyday wear, and from a sizing perspective, they’re much closer than you might expect.
The good news is that I wear the same size in both.
Here’s the quick answer:
My regular US 9 works perfectly in the Nike P-6000 and the Nike Vomero 5, so I wouldn’t change sizes when moving between them.
If you have narrow feet, I’d still start true to size. If you prefer a very close fit, you could even experiment with going half a size down in the P-6000.
For normal-width feet, true to size is where I’d begin for both sneakers.
The same applies to slightly wide feet like mine. Although the P-6000 feels a little closer around my toes than the Vomero 5, it never reaches the point where I feel the need to size up.
If you have wide feet, I’d still try the Vomero 5 true to size. The P-6000 is the one I’d be more cautious with. If your toes usually need extra room, consider going half a size up.
Now, the P-6000 isn’t the only retro runner I compared with the Vomero 5. I also wore the Nike Vomero 5 and New Balance 530 side by side to see how their sizing differs.
To give you a size comparison, I go the same size in these as I do other Nike sneakers like the Dunks, and I go a half size down in Air Force 1s.
That’s one of the best examples of why I never assume every Nike sneaker fits the same, and I explain exactly what I found when comparing the Nike Dunk and Air Force 1.
So, although I wear the same size in both, they create space around my feet in very different ways. That’s exactly what I’ll break down in the rest of this comparison.
Nike Vomero 5 vs P6000 Sizing
Before we get into the comparison, here’s a quick look at my feet so you can judge whether my recommendations are likely to work for you.
My Sizing Profile
- Brannock Size: US 9 (9D to 9E)
- Foot Shape: Slightly wide forefoot
- Preferred Fit: Snug and comfortable, with enough room for my toes to move naturally
- Typical Nike Size: US 9
I generally like my sneakers to feel secure without squeezing my toes. A little space at the front is ideal, but I don’t enjoy shoes that leave unnecessary room around my foot.
If your feet and preferences are similar to mine, my experience should be a good starting point. If your feet are much narrower or wider, you may come to a different conclusion.
If you’re trying to choose between different Vomero models, I’ve also compared how the Vomero 5, Vomero Plus, Vomero Premium, Vomero 18, and the rest of the lineup fit.
Same Size, Different Amount of Toe Space
One of the first things I noticed was that wearing the same size didn’t give me the same experience around my toes.
My regular US 9 works in both shoes, yet they use that space very differently.
With the Vomero 5, my toes immediately feel like they have room to spread naturally. There’s extra breathing room around my forefoot, and I never notice the sides of the upper pressing against my little toe or the outside of my foot.
Even after hours of wear, that sense of freedom stays the same.
With the P-6000, my toes sit a little closer together, and I can tell the front of the shoe follows my foot more closely.
It’s subtle rather than dramatic, but I notice it every time I switch from the Vomero 5.
The important part is what didn’t happen.
Despite that slightly closer feeling, I never wanted to size up. My slightly wide forefoot still had enough usable space, so my regular US 9 remained the right choice.
That’s where I think people often get the wrong idea.
Feeling your toes a little closer together doesn’t automatically mean the shoe is too small. On my feet, the P-6000 simply uses the available space differently than the Vomero 5.
If your feet are narrow, normal, or slightly wide, I’d still start true to size in both.
If you have wide feet, that’s where our experiences may begin to diverge. The extra freedom I enjoy in the Vomero 5 is more likely to suit you, while the P-6000 may be the model that makes you consider going up half a size.
What Happens Behind the Toes?
The differences don’t stop at the front of the shoe. Once I look beyond my toes, each sneaker holds the rest of my foot in its own way.
Midfoot
The P-6000 feels surprisingly comfortable through the middle of my foot.
Even though the front of the shoe sits a little closer around my toes, I never get that same sensation across my midfoot.
The upper wraps around this area without creating pressure, so my regular US 9 feels natural from the first wear.
The upper on the Vomero 5 feels a bit more substantial around my foot, but it also adapts more easily as I tighten or loosen the laces.
I notice the shoe following my foot a little more closely through the middle without ever feeling restrictive. They simply secure my foot in different ways.
Ankle & Heel
The biggest difference back here is the amount of padding.
The P-6000 has a noticeably thinner collar around the ankle. I can feel that every time I switch from the Vomero 5.
It doesn’t make the shoe feel unstable, but there’s less cushioning around the back of my foot.
The collar of the Vomero 5 is thicker, softer, and wraps more generously around my ankle, which gives the shoe a more cushioned feel before I even take a step.
But I didn’t need to size down in the P-6000 because of its thinner padding, and I didn’t need to size up in the Vomero 5 because of the extra cushioning.
Both feel right in my regular Nike size, even though they hold the back of my foot quite differently.
Does True to Size Still Work After Hours on Foot?
For me, yes. Spending more time in both shoes only reinforced that my regular Nike size was the right choice.
The P-6000 was the one I paid closest attention to. Since I could already feel my toes sitting a little closer together, I wanted to see whether that would become a problem after a few hours.
It never did.
My feet naturally expanded as the day went on, but the shoe never reached the point where I wished I’d bought a 9.5.
The sensation around my toes became a little more noticeable than it was during the first few minutes, yet it stayed comfortably within the range I’d expect from a shoe that fits correctly.
The Vomero 5‘s extra space around my toes never made me wonder if I’d chosen a size that was too big.
Even after wearing it for hours, my foot stayed where I wanted it, and I never found myself thinking that half a size down would have been a better choice.
I also kept an eye on heel movement because that’s often the first sign that a shoe has more room than it needs. My heel stayed planted in both, and I didn’t have to stop and adjust the laces halfway through the day.
That’s probably the biggest takeaway from wearing them beyond the initial try-on.
Which One Is Easier to Size for Your Foot Shape?
For most people, I’d say the Vomero 5 is the easier shoe to size. Its roomier front makes it more accommodating across different foot shapes, while the P-6000 asks you to pay a little more attention if your feet are on the wider side.
| Foot Shape | Vomero 5 | P-6000 |
|---|---|---|
| Narrow | True to size | TTS, or ½ size down for a closer fit |
| Normal-width | True to size | True to size |
| Slightly wide | True to size | True to size |
| Wide | True to size | Consider ½ size up |
| High-volume | True to size | Consider ½ size up if you often need extra room |
The key distinction is between slightly wide and genuinely wide feet.
My feet fall into the slightly wide category, and my regular US 9 works well in both sneakers. Even though the P-6000 keeps my toes a little closer together than the Vomero 5, it never feels too tight.
If your feet are genuinely wide or you regularly size up in narrower Nike models, I’d consider trying half a size larger in the P-6000.
The Vomero 5 is more forgiving around the front of the foot, so I’d still begin with your regular Nike size before making any adjustments.
When I’d Actually Change Size
Most people can stop at true to size, but there are a few situations where I’d do something different.
I’d consider going half a size down if…
You have narrow feet and enjoy a close-fitting sneaker.
That’s especially true for the P-6000. Since it already sits a little closer around my toes than the Vomero 5, someone with narrow feet may find that going half a size down gives them the secure feel they’re after.
I wouldn’t make that recommendation for the Vomero 5. My regular size already feels balanced, and I don’t think there’s enough extra length to justify sizing down.
I’d consider going half a size up if…
This mainly applies to the P-6000.
If you have genuinely wide feet or often need extra room in Nike sneakers, I’d try half a size up. I can already feel my toes sitting a little closer together at true to size, so I think a wider foot is more likely to appreciate the additional space.
When it comes to the Vomero 5, I’d still begin with your regular Nike sneaker size because there’s already more room around the front of the shoe. I’d only move up if you consistently size up in most Nike models.
When I wouldn’t change size
For normal and slightly wide feet like mine, I’d leave both shoes exactly where they are. Start true to size in both, then only move away from that if your foot shape gives you a clear reason to.
Nike Vomero 5 vs P6000 Sizing FAQ
Do I need to size up or down in Nike P-6000 shoes?
For most people, no.
I’d start with your regular Nike size. That’s what worked best for me, even with my slightly wide forefoot.
The only exceptions are people with genuinely wide feet, who may prefer going half a size up, and those with narrow feet who like a very close fit, where half a size down could be worth trying.
Should I size up in the Nike Vomero 5?
Most people won’t need to.
My regular Nike size gives me all the room I need around my toes and forefoot. I’d only think about sizing up if you consistently need extra space in Nike sneakers because of particularly wide feet. Otherwise, true to size is the best place to start.
Are Nike Vomero 5 and P-6000 good for wide feet?
Both can work, but I’d give the edge to the Vomero 5.
Its front feels more accommodating, so I’d confidently recommend trying your regular size first.
The P-6000 also worked well for my slightly wide feet at true to size, but if your feet are genuinely wide, you’re more likely to appreciate the extra room that comes with going half a size up.
Do Nike Vomero 5 and P-6000 come in half sizes?
Yes.
Both models are available in full and half sizes, which makes it much easier to fine-tune the fit.
For me, that wasn’t necessary because my regular US 9 worked well in both. But having half sizes is especially useful if you’re between sizes or if you’re trying to accommodate a wider foot without making the shoe feel unnecessarily long.
Can I wear the same size in the Nike P-6000 and Nike Vomero 5?
Yes.
I wear my regular Nike size in both models.
Although they create space around my foot differently, neither shoe gives me a reason to change sizes.
Which sneaker is better for wide feet?
I’d lean toward the Vomero 5.
Its front feels more accommodating, so I’d happily recommend starting true to size.
The P-6000 can also work, but if your feet are genuinely wide, I’d be more open to trying a half size up.
Do the Nike P-6000 and Nike Vomero 5 stretch over time?
Not enough to influence sizing.
The uppers become a little more flexible with wear, but neither shoe changes enough that I’d buy a pair expecting it to stretch into the right size.
Which sneaker is easier to buy online?
I’d say the Vomero 5.
My regular Nike size worked exactly as I expected.
The P-6000 isn’t difficult to size either, but people with wider feet have a little more to think about before ordering.
Can I wear orthotics in the P-6000 and Vomero 5?
Yes, but I’d always try the shoes with your orthotics before deciding on a size.
Replacement insoles and orthotics take up space inside the shoe, so they can change how both models feel, particularly the P-6000 because it already sits a little closer around the front of my foot.
Final Thoughts
If I were buying these again today, I’d make exactly the same decision.
I’d stick with my regular US 9 in both the Nike Vomero 5 and the Nike P-6000. The difference is that I know what to expect once they’re on my feet.
The P-6000 keeps my toes a little closer together, but not enough to make me chase the next size up. I’d only consider that if my feet were genuinely wide. Otherwise, I’d happily stay true to size.
Hopefully, this Nike Vomero 5 vs Nike P-6000 sizing comparison has helped you decide where to start.
Knowing that both work true to size only gets you halfway there. Understanding how they use that space is what really helps you choose between them.
Have you worn both? I’d love to know whether you stayed true to size or ended up sizing differently. Let me know your foot shape and the size you wear in each pair.
