Data confidence
Why Converse and New Balance differ
That works out to roughly 13mm 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.
