What US size is 26.5 cm?

Often around US 9.5 in Nike, but brands differ — use the table and model guides.

How should I measure?

Stand, heel against a wall, mark longest toe; measure in cm. Then open the cm converter and the model fit page.

Foot length in centimetres mapped to brand US/EU labels from reference charts — not a Mondopoint guarantee.

Nearest chart row within 0.35 cm — labels can still disagree across brands.
