What US size is 27 cm?

Often around US 10 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.

What US size is 27 cm?: Often near Nike US 10; compare brands in the table, then read model guides.
Is chart cm the same as lab internal length?: No. Chart cm is recommended foot length / Mondopoint-style. Lab internal length (when we have it) is a different measurement on model pages.
