This document provides three shoe size conversion charts that cover the major shoe size systems (the Mondopoint system, the European system and the system used in the United Kingdom), as well as the systems used in China, Japan respectively , the Republic of Korea and the United States. These tables are based on measuring the length of the foot, which is the logical starting point for any shoe size marking system. The tables include the following information: Table 1 — Technical conversion of adult shoe sizes; Table 2 — Recommended marking for adult shoe sizes (simplified); Table 3 — Conversion of children's shoe sizes. NOTE Given the different ways in which the systems have been developed and interpreted for many years without being formalized and the lack of a solution to the problem of converting shoe sizes, Tables 1 and 2 provide guidelines that may be useful to the consumer.
