Mondopoint

Mondopoint is the international shoe sizing system defined by ISO 9407. It measures shoe size by foot length in millimeters: a Mondopoint 270 fits a 270 mm foot. Most full-size steps are 5 mm; half-size steps 2.5 mm.

Adopted as the official system for ski boots (where Mondopoint is the dominant convention in retail), military boots, professional kitchens, and the IOC for athletic footwear. Japan uses Mondopoint as the consumer standard (a JP 26.5 is 265 mm). Most of the Western world labels with Mondopoint internally but displays US/UK/EU equivalents at retail.

Convert Mondopoint to any regional system via our shoe size converter. Our internal storage uses foot-length-in-mm (effectively Mondopoint) so the conversion to other systems is just a lookup table.
