How do the Nike Air Max 1 fit for wide or narrow feet?

Should I size up in the Nike Air Max 1 for thick socks or break-in?

Fit depth guide

Nike Air Max 1 length is often true to size for Nike runners and lifestyle wearers, with a different width story than Air Force 1. The visible Air unit and mudguard shape change how volume feels in the forefoot.

Do not assume AF1 half-down applies. If Dunk fits you TTS, AM1 is frequently in a similar length conversation â€” still check width if you have a high-volume midfoot.

Half sizes matter for lockdown over the Air window. Compare with Air Max 90 on model pages. Use cm to model only as a chart hint plus the fit offset.
