Shoe Size Converter
Buying shoes from overseas? Enter your size in one system and see the US, UK, and EU equivalents side by side.
How it works
Shoe sizes all trace back to foot length, but each region scales it differently. The converter lines up US, UK, and EU on a shared chart so you can jump between them in one step.
US and UK sizes run close but aren't the same — a US men's size is usually about half a size larger than the UK number. Women's US sizes sit roughly a size and a half above the UK figure.
EU sizing is shared between men and women and climbs faster, so a US men's 9 is around EU 42.5. Because brands cut differently, treat the result as a strong starting point and check a fit guide when you can.
Frequently asked questions
What is a US men's 9 in UK and EU?
A US men's 9 is about a UK 8.5 and an EU 42.5. Brands vary a little, so if you're between sizes it's worth sizing up for a roomier last or down for a snug one.
Are men's and women's sizes different?
In the US and UK the scales differ — a women's size runs larger than the men's number for the same foot. The converter keeps them separate, so pick the right one before you read the result.
Why is EU sizing the same for men and women?
EU sizes are based directly on foot length in a unit called the Paris point, so one scale covers everyone. That's why a men's and women's EU number can match even when US sizes don't.
Will these sizes fit every brand?
Sizing charts get you close, but running shoes, boots, and dress shoes can each fit differently even at the same label. Check the brand's own guide and, if you can, try before you commit.
