Global Shoe Size Chart
We use the standard conversions published by Nike, Adidas, and major European brands. Enter any system you know (US, UK, EU, or foot length in cm) and we'll return the equivalents.
When a size falls between two, round up — shoes should not be tight. Leave about 1 cm of toe room in athletic shoes.
Frequently Asked Questions
What's the difference between US and UK sizes?
US sizes are about 1 size larger than UK (for both men and women). Men's UK 9 = US 10. Women's UK 6 = US 8.5.
How do I measure foot length?
Stand on paper, mark heel and longest toe, measure in cm. Do it in the evening when feet are largest, with the socks you'll wear in the shoe.
Are men's and women's sizes the same?
No — they use different scales. A women's US 9 is roughly a men's US 7.5 in the same length.
Why do sizes vary by brand?
There's no single global standard. Italian, Japanese, and American brands each calibrate differently — always check brand-specific size guides when possible.
