Data confidence

Why Brooks and New Balance differ

Brooks and New Balance run about the same size.

That works out to roughly 2mm of real shoe length. We map every size through foot length in millimetres — the canonical axis — and then re-apply each brand's 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. See how we calculate for how we measure fit offsets.
