Shoe size technical specification from International Standards Organisation. It contains three conversion tables (for adults and children) which feature major shoe sizing systems (e.g., Mondopoint, United States, European, United Kingdom, China, and Japan). Each table is based on actual foot length measurement (insole) in millimeters; typical last length ranges are also included. The standard includes conversion tables for Mondopoint (USSR/Russian/Chinese/Japanese/Korean systems) using length steps of 5 mm and 7.5 mm, European Paris point system, and UK 1/3 inch system. The standard has also been adopted as Russian GOST R 57425-2017. The standard is maintained by ISO/TC 137, which also developed ISO/TS 19408:2015
Shoe size , Mexico, and European countries. Mondopoint system is also used by NATO and other military services. The standard is maintained by ISO Technical Committee 137 "Footwear sizing designations and marking systems"; as of 2018, a new revision is under development. In Japan, Taiwan and South Korea, the Mondopoint system is used as defined by national standard JIS S 5037:1998 and its counterparts CNS 4800-S1093:2000 and KS M 6681:2007. Foot length and girth (foot circumference) are taken into account. The foot length is indicated in centimetres; an increment of 5 mm is used. The length is followed by designators for girth
