How Shoe Sizing Systems Work
Shoe sizing varies significantly by country and brand. US sizes differ by gender — women’s sizes run about 1.5 sizes larger than men’s. EU sizes are based on the length of the last (the foot mold), measured in Paris points (⅔ cm each). UK sizes are similar to US men’s sizes but start from 0. CM sizes directly measure foot length in centimeters and are used in Japan and some other Asian countries.

Frequently Asked Questions
What is a US size 10 in EU?
Men’s US 10 = EU 44. Women’s US 10 = EU 41. The difference exists because women’s US sizes are 1.5 sizes larger than men’s for the same foot length.
How do I convert US to UK shoe sizes?
For men: UK size = US size − 0.5. For example, US 10 = UK 9.5. For women: UK size = US size − 2. For example, women’s US 10 = UK 8.
Are EU shoe sizes the same for men and women?
Yes, EU sizes are gender-neutral and based purely on foot length. EU 42 means the same foot length regardless of gender. The conversion from US to EU differs by gender because US sizing uses different scales for men and women.
How do I measure my foot for shoe size?
Stand on a piece of paper and trace your foot. Measure the longest distance from heel to toe in centimeters. Compare to sizing charts: 25 cm = US men’s 7, 26 cm = US men’s 8, 27 cm = US men’s 9, etc. Always measure both feet and use the larger measurement.
Why do shoe sizes vary between brands?
Shoe sizes are not standardized across brands — each manufacturer uses its own last (foot mold) design. A Nike US 10 may fit differently than an Adidas or New Balance US 10. Width also varies (narrow, regular/medium, wide, extra-wide), which is rarely reflected in the size number.
