Comparison
EU vs Japanese Shoe Sizes
JP/CM labels may differ from measured foot length. Use a manufacturer chart rather than a fixed multiplier.
Nike explicitly separates CM/JP labels from Foot Length. A metric label is not enough to determine what is measured.
| JP (cm) | EU | US Men's | US Women's |
|---|---|---|---|
| 24.0 | 38.5 | 6 | 7.5 |
| 25.0 | 40 | 7 | 8.5 |
| 26.0 | 41 | 8 | 9.5 |
| 27.0 | 42.5 | 9 | 10.5 |
| 28.0 | 44 | 10 | 11.5 |
| 29.0 | 45 | 11 | 12.5 |
Key takeaways
- Metric labels are not always foot measurements.
- Do not use a fixed JP-to-EU multiplier.
- Confirm the current product chart.
