Break-in

Minimal length change; leather softens slightly but stays slim

Summary

Nike Cortez commonly runs short and narrow versus modern sneakers. Most wearers size up half a size; wide feet may still feel squeezed. Narrow feet can sometimes stay TTS for a locked vintage fit. Recent Cortez updates stay true to that slim heritage last.

Women’s sizing

Nike uses a 1.5-size women’s→men’s US gap (not always 1.5). Convert your women’s US size with this model’s fit offset built in.
