Nike P-6000 sizing guide: do they fit true to size?
Sizing · 5 November 2026
The short answer
The P-6000 is built on a retro running last, and most wearers find it fits true to size for length. The toe box is a little narrower than a modern knit trainer like an Air Force 1, which is worth knowing if you have wide feet: the mesh panels give a bit, but the synthetic leather cage holds the midfoot snugly. If you normally take a half size and you're between two whole sizes, going up is the safer call for comfort on longer walks.
We stock the P-6000 in whole UK sizes 3–12. Here's how to land on the right one without guessing.
Measure your feet first (it takes two minutes)
Foot size drifts with age, and most people's feet are slightly different sizes — always size for the bigger foot.
- Stand on a piece of paper against a wall, heel touching the wall.
- Mark the tip of your longest toe (not always the big one).
- Measure the distance from the wall to the mark in centimetres.
- Do it in the evening — feet swell during the day and are at their largest then.
- Measure wearing the socks you'll actually wear with the shoes.
UK size chart
Match your foot measurement to your usual UK size, then cross-check the EU and US conversions — this is the chart we use across the whole shop, so every pair on CrepDirect follows it:
| UK | EU | US women | US men |
|---|---|---|---|
| 3 | 35.5 | 5 | 4 |
| 4 | 37 | 6 | 5 |
| 5 | 38 | 7 | 6 |
| 6 | 39 | 8 | 7 |
| 7 | 40.5 | 9 | 8 |
| 8 | 42 | 10 | 9 |
| 9 | 43 | 11 | 10 |
| 10 | 44.5 | 12 | 11 |
| 11 | 46 | 13 | 12 |
| 12 | 47 | 14 | 13 |
A guide only. Brands fit differently, and when you're between two sizes most people are happier going up in a retro runner.
P-6000 fit notes
A few things specific to this shoe:
- Length: true to size for most wearers.
- Width: regular; the synthetic overlays hold the midfoot, so wide-footers may prefer half a size up — in whole sizes, that means taking the next size up.
- Break-in: the upper softens after a few wears; the sole is cushioned from the first wear.
- Socks matter: thick crew socks can feel tight in the toe box of a narrow fit — thin or standard sports socks are the natural pairing.
