ASICS vs Reebok Shoe Size Comparison

Reebok fits about the same as ASICS, so keep your usual size as the starting point. The estimate uses a fit-offset difference of about 0mm plus each brand's fit evidence — not the size labels alone. Use the table below to convert any ASICS US size to a starting size in Reebok, with UK, EU and CM alongside.

Why ASICS and Reebok differ

ASICS and Reebok run about the same size.

That works out to roughly 0mm 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.
