Using the converter
Select a men’s US size, then choose Convert size. This tool covers the original men’s US 3.5–10.5 range, corresponding to women’s US 5–12. Use Nike’s full chart for sizes outside this range.
The 1.5-size offset applies to the US categories shown here. Do not add 1.5 to a UK, EU or CM label. A size conversion does not establish equal width or the same fit across different models.
Check the shoe’s measurements
Use Nike’s current foot-measurement instructions for the shoe you are considering. Nike distinguishes the CM/JP label from its measured foot-length column. Check the product’s width and fit notes as well as the converted US size.
