Adidas Shoe Size Guide
Adidas sizing is famously consistent: men's, women's and kids' lines all run true to size across classics like Stan Smith, Samba and Gazelle, and across the running and football ranges. The one outlier is Ultraboost, which tends to feel slightly long - many runners size down half for a tighter midfoot fit.

Frequently asked questions
Do Adidas shoes run true to size?
Yes - Adidas's men's, women's and kids' lines all run true to size across the bulk of the range, including Stan Smith, Samba, Gazelle, Forum and the running silhouettes. Order your usual size in your home system and the conversion in the chart below should fit as expected.
Does Adidas Ultraboost run long?
Ultraboost runs slightly long thanks to the Primeknit upper, which stretches as it conforms to the foot. Many wearers find sizing down half a size gives a more secure midfoot lockdown without losing toe-box room.
How do Adidas sizes compare to Nike?
Adidas and Nike use the same underlying US/UK/EU conversions, so a size 9 in one is conceptually a size 9 in the other. The difference is fit: Nike women's runs slightly small (size up half), while Adidas women's runs true to size - so most women take their true Adidas size and bump up half for Nike.
Sizes are approximate and may vary by Adidas model and last. Always check Adidas's product-page size chart before buying.
