Nike Shoe Size Guide
Nike sizing is consistent across its lifestyle, running and basketball lines, with one quirk worth knowing: women's styles tend to run slightly small, while men's and kids' styles fit true to size. If you are between sizes in a Nike women's pair, size up half - for men's and kids', stick with your usual.

Frequently asked questions
Do Nike shoes run small?
Nike women's shoes run slightly small for most lifestyle and running silhouettes - sizing up half a size is the safest default. Nike men's shoes generally fit true to size, so the size you wear in other major US brands should carry across.
How do Nike size conversions compare between US and UK?
Nike follows the standard half-size offset between US and UK: women's US 8 is roughly UK 5.5, and men's US 9 is roughly UK 8. The chart below shows the full range; if you are between sizes, size up half a size in women's and stay true in men's.
Are Nike kids’ shoe sizes true to size?
Yes - Nike's Big Kids (GS), Little Kids (PS) and Toddler (TD) lines run true to size. Many Nike GS models share lasts with the men's range, so adults with smaller feet can save money by sizing into Big Kids using the US GS = US men's − 1 rule.
Sizes are approximate and may vary by Nike model and last. Always check Nike's product-page size chart before buying.
