Understanding Japanese vs US Shoe Sizing
The Simplicity of the Japanese System
The Japanese (JP) shoe sizing system is one of the most logical in the world as it's based directly on the length of the foot in centimeters (CM). A JP size of 26 means the shoe is designed for a foot that is 26cm long. This is also a key part of the ISO/TS 19407:2015 international standard.
Why Direct Conversion is Best
Because the US system is not linear and has different scales for men and women, any simple mathematical formula to convert from JP to US will be flawed. The most reliable way to convert is to use an official conversion chart that maps each JP (CM) size to its corresponding US size, which is what our tools and tables provide.
