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

Surface sizing solutions consist of mainly modified starches and sometimes other hydrocolloids, such as gelatine, or surface sizing
