Nike sizing, explained
How Nike's lineup actually fits — what runs large, what runs narrow, and how to pick the right size across silhouettes.
True to size, with exceptions
Most Nike performance running shoes — Pegasus, Vomero, Invincible — fit true to size. The exceptions are the lifestyle classics.
Air Force 1 and Air Max run long
Both silhouettes fit roughly half a size large. Most wearers go down half a size, especially in the AF1 Low.

Jordans run large too
Air Jordan 1 fits about half a size large. Jordan 4 fits true to size. Jordan 11 is true to size but narrow.
Women's vs men's sizing
Nike publishes a women's equivalent that is 1.5 sizes higher than men's. A men's 8 = a women's 9.5 in the same shoe.
