Shoe size charts by brand

Every brand cuts its sizing a little differently. Pick a brand for its full US, UK, EU and cm size chart — men's and women's — or use the converter to translate a size from one brand to another.

How brand-to-brand conversion works

A US 10 isn't the same length in every brand — a Nike US 10 fits a foot about 27.1 cm long, while an Adidas US 10 fits closer to 27.6 cm. Each brand chart above is built from that brand's official sizing, and our converter anchors on foot length in centimeters to translate between them accurately. Once you've got the right size, the per-model fit guides tell you whether a specific shoe runs big, small, or true to size.
