It is part of ISO standard 9407:2019, which describes the specification for Mondopoint system of sizing and marking. 1 It has the potential to replace various mutually incompatible shoe sizing systems used in different countries. Most of these systems use arbitrary numbers that do not relate to anything obvious. Even worse, different sizing systems are often used for men, women and children.
