pro tips
Shoe sizes are approximate and brands differ — the numbers here are a guide, not a blood oath.
US men's to US women's is roughly +1.5. Society made it complicated; the math didn't.
Kids and adults use different numbering — toggle the mode before you buy. The feet will thank you.
what it does
Type a shoe size, pick its system, and every other system updates at the same time. Centimetres, EU, UK and the US men's and women's scales — the whole shoe rack in one screen.
The conversion runs through the foot length in centimetres, the only language every brand quietly agrees on. Click any result to copy that particular size, because someone will always ask for the number in US.
Kids use a different numbering, so there's a toggle for that too — because a "size 5" means very different things to a toddler and to an adult. Handy for online shopping and the eternal "what's my US size, again?"
Use it when an EU site only speaks EU sizes and you think in US, when a European brand asks for your size and you only know your US number, or when the kids have grown a size between seasons and the numbers stopped making sense. Toggle adult or kids, type one number, and every system answers at once — click any result to copy it before you forget which was which.
quick answers
How do you convert EU to US sizes?
The converter runs through the foot length in centimetres — type an EU size and it gives you US men's, US women's and UK in one screen.
Why are men's and women's sizes different?
Because feet, and marketing, decided so. A US men's 9 is roughly a US women's 10.5 — society made it complicated; the math didn't.
Do brands all use the same sizes?
Not exactly — sizing is approximate and brands differ. Use this as a guide, and when in doubt, measure the foot in centimetres. That's the language every brand actually speaks.
Is there a kids mode?
Yes — toggle adult/kids. Kids use a different numbering, so a "size 5" means something very different to a toddler and to an adult.
