Frequently asked questions
- How do I convert US to EU shoe size?
- Enter your foot length in cm for the most accurate EU size, or pick US as the system and read the EU result. EU is roughly (cm + 1.5) × 1.5.
- Are men's and women's shoe sizes the same?
- No. For the same foot length, women's US sizes run about 1.5 sizes higher than men's, which is why this tool asks for the scale.
