How to measure your feet correctly
A simple, accurate method to measure your feet at home and find the size that really fits.
- Stand on a sheet of paper, heel against a wall.
- Mark your longest toe and measure the length.
- Match the length to the size chart.
| EU | US (M) | UK | cm |
|---|---|---|---|
| 40 | 7 | 6 | 25 |
| 41 | 8 | 7 | 26 |
| 42.5 | 9 | 8 | 27 |
| 44 | 10 | 9 | 28 |
Why trust Fork Shoes?
Ordering shoes online is a gamble when every brand labels sizes differently. A US 10 at Nike, Adidas and New Balance is built for three slightly different feet, and some models run half a size off their own brand's chart.
Our guides start from each brand's official foot-length chart, then add what the chart can't tell you: which models run long, which ones pinch at the toe, and when wide feet should size up. Every guide ends with a clear recommendation, not a shrug.
