Shoe size conversion questions
Are US and UK shoe sizes the same?
No. Adult UK sizes are usually about one size lower than US men's sizing and about two and a half sizes lower than US women's sizing.
How do I convert EU shoe size to US?
Use EU size as a starting point, convert it to foot length in centimeters, then map that length to the closest US men's or women's half size.
Why do shoe size conversions vary by brand?
Brands use different lasts, toe shapes, materials, and width assumptions, so conversion charts should be treated as close estimates.
How much toe room should kids have?
Kids generally need about a thumb width of toe room so the shoe fits during walking, running, and normal growth.
