Why Converse and Brooks differ
Converse runs ~1 size smaller than Brooks.
That works out to roughly 11mm 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.
