Nike vs Puma Shoe Size Comparison
Puma runs about half a US size larger than Nike, so you may need to size down. The gap is about 4mm in measured shoe length plus each brand fit bias. Use the table below to convert any Nike US size to a starting size in Puma, with UK, EU and CM alongside.

Data confidence
Why Nike and Puma differ
That works out to roughly 4mm of real shoe length. We map every size through foot length in millimetres and then re-apply each brand empirical fit offset, so the comparison reflects how the shoes actually fit rather than how they are labelled.
Brand-level estimate: per-model fit can vary by a full size or more within a brand.
