Understanding EU vs US Shoe Sizing
Why Simple Formulas Fail
While you might see formulas like "US Size = EU Size - 31," they are not reliable. US and EU sizing systems use different starting points and increments, especially between men's and women's shoes. A direct formula doesn't account for these complexities.
Using ISO Standard Conversion Charts
The best practice is to use a conversion chart based on international standards like ISO/TS 19407:2015. This ensures you are using globally recognized data. Our charts below provide a direct mapping from your EU size to the correct US size, removing guesswork.
