Nike Size Guide
Does Nike run small?
Yes — Nike runs about half a size small in footwear, especially in running shoes and Air Force 1s. Most people should size up half a size from their measured size. Apparel runs athletic and slim: if you're between sizes or prefer a relaxed fit, size up.

Conversion & fitting tips
- Shoes: go up half a size from your true measured size; if you wear thick athletic socks, consider a full size up in running shoes.
- Leggings and tights: Nike's compression styles run especially snug: size up for a comfort fit, stay true for a compression fit.
- UK vs US women's apparel: UK sizes are numerically 4 higher (US 8 = UK 12).
- Dri-FIT tops: designed with an athletic taper through the waist; broad-shouldered builds often prefer one size up.
