Nike size chart
Nike's chart has two cm columns: 'CM / JP' is the size on the box, 'Foot Length' is your foot. Go by the foot length. EU sizes move in uneven steps (38 → 38.5 → 39 → 40).
- Between sizes, Nike recommends sizing up.
- The same shoe has three US sizes: men's, women's and youth (Y).
- Runners often go half a size up – feet spread when running.

Questions and answers
Frequently asked
01Do Nike shoes run small?
Nike's advice: if your foot is between sizes, size up. Check the length against the 'Foot Length' column, not the cm on the box.
02What's the difference between 'CM / JP' and 'Foot Length'?
'CM / JP' is the size label on the box; 'Foot Length' is the foot that size is made for. They are not the same.
