Adidas shoe size chart

Unisex and kids' sizes, copied from Adidas's own chart. Checked 25 Oct 2026.

How Adidas sizing works

Adidas uses one chart for everyone, with men's and women's US sizes side by side. Women's US runs one size above men's on every row.

Adidas EU sizes come in thirds, like 42 2/3 and 43 1/3, so they rarely match another brand's EU number exactly. The cm column is foot length.

This is the chart from Adidas's own size support pages. Women's US sizes stop at 15.5.
