Frequently asked questions
How accurate are these conversions?
They follow common retailer charts and are a close starting point. Fit still varies by brand and shoe shape, so check the maker's own size guide when you can.
What does the CM value mean?
It is the approximate length of your foot in centimetres. Measuring your foot and matching the CM column is often the most reliable way to size.
Why are some EU sizes shown with a half?
EU sizing does not map evenly onto US half sizes, so a half value is the nearest standard EU size for that US size.
Do men's and women's charts differ?
Yes. For the same US number, men's and women's UK, EU and CM equivalents are different, so be sure to pick the right one.
Is anything uploaded?
No. The conversion runs entirely in your browser.
