Shoe Size Conversion Guide
Every listing on this site is normalized to US Women's sizing using the chart below — the same one powering the size filters. Brands vary, so always double-check the retailer's own chart before ordering.

|---|---|---|---|
| 12 | 10.5 | 10 | 43 |
| 12.5 | 11 | 10.5 | 44 |

A few honest caveats
- US Men's ↔ Women's varies by brand. Most use a 1.5-size offset (shown above), but some use 1 or 2. When a brand publishes its own offset, our listings use that instead.
- EU sizing is the least standardized. The column above follows the most common convention; individual brands can run a half size either way.
- Width matters as much as length. Many extended-size feet also need wide widths — look for the W / WW markers on size chips, and set your Width Preference in your account.
How the size filter works
Filtering by a size shows shoes available within ±½ size of your pick — sizing between brands simply isn't precise enough for exact matching to be useful. "My size" mode (from your account defaults) widens that to a full size in each direction, floored at 12.
