Brand size guides
How each major brand fits — what runs large, what runs narrow, and how to pick the right size.
Brand
Nike
Nike runs true to size for most styles. Air Force 1 and Air Max fit slightly large — consider going down half a size. Jordan 1 fits roughly half a size large.
Brand
Adidas
Adidas runs slightly narrow and about a half size small for Ultraboost and Stan Smith. Consider sizing up half a size, especially with thicker socks.
Brand
New Balance
New Balance generally fits true to size with wider toe boxes (especially the 990 and 2002R lines). Available in multiple widths (B, D, 2E, 4E).
Brand
Puma
Puma fits true to size for most lifestyle silhouettes; performance running shoes can feel slightly narrow.

H&M tends to run small, especially for women's tops and dresses. Consider sizing up one full size.
