What is US size 9 in EU?
For men, US 9 is about EU 42.5; for women, US 9 is about EU 40. Pick the gender first — men's and women's sizing differ.
Are US men's and women's sizes the same?
No — a US women's size is about 1.5 sizes larger than the same US men's size, so women's US 9 is roughly men's US 7.5.
Why do sizes vary between brands?
Brands use different lasts and fit models, so the same nominal size can differ by half a size or more. Use the foot-length estimate and check the brand's own chart before ordering.
