Women's to Men's US Shoe Size Conversion
Women's US sizes are typically 1.5 size steps above men's US for the same foot length — women's US 10 ≈ men's US 8.5. Unisex shoes (Converse, Vans) often use men's sizing on the label; always check whether the chart is men's, women's, or unisex before converting.

Formula (Layer A): US men's ≈ US women's − 1.5 (same foot length; unisex styles may use men's chart). See how we calculate for the full methodology.
How to read this conversion
The anchor row converts US Women 9 to 250mm first, then displays it as US Men 7.5. That millimetre anchor is why the same size can be compared against brand and model fit without re-entering the number.
- Foot length in millimetres is the pivot; brand fit is applied later on brand and model pages.
- US women's labels are 1.5 sizes above US men's at the same foot length.
- US men's labels use the barleycorn formula, then round to the nearest half size.
