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

Why Puma and Nike 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.
