Why New Balance and Nike differ

That works out to roughly 8mm 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.
