How to Convert US to EU Shoe Sizes
The Challenge with Conversion Formulas
You may find simple formulas online like "add 31 to your US size," but these are often inaccurate. US sizing is not linear and has different starting points for men and women. Furthermore, half-sizes and brand variations make a simple formula unreliable.
The Authoritative Method: Conversion Charts
The most reliable method is using a conversion chart based on the international ISO/TS 19407:2015 standard. This standard provides a globally recognized system for shoe sizing. Our charts below are based on this data, ensuring you get the most accurate conversion possible. Instead of relying on a flawed formula, simply find your US size in the table to see its direct EU equivalent.
