Nike shoe size chart
Honest note first: Nike's own published chart can differ from the general international chart by half a size on some models. Key men's rows from Nike's public chart are below — for the exact model you are buying, the brand's official chart is the final word.
| US Men | UK | EU | Foot (cm) |
|---|---|---|---|
| 8 | 7 | 41 | 26 |
| 9 | 8 | 42.5 | 27.1 |
| 10 | 9 | 44 | 28 |
| 11 | 10 | 45 | 28.8 |
| 12 | 11 | 46 | 29.6 |
Nike charts UK sizes a full size below US on these rows, where the general chart shows only half a size — a classic reason a straight general conversion feels off in Nikes. Nike also measures foot length slightly differently (a US 9 is listed at 27.1 cm). Many runners size up half a size in Nike racing shoes.
