The US system is used throughout North America and differs from UK sizes by approximately one full size (US 9 ≈ UK 8). Athletic shoe sizes may vary slightly between brands.

US Women's shoe sizes run approximately 1.5 sizes larger in number than US Men's for the same foot length, with US Women's 9 corresponding to about 25.4 cm foot length. This offset often causes confusion when shopping for unisex or athletic shoes. US Women's 9 ≈ US Men's 7.5 ≈ EU 40 ≈ UK 6.5.
