Japanese Shoe Size Conversion
Japanese shoe sizes are simply the foot length in centimetres — convert them to US, UK and EU here.
Japanese (JP) sizing is one of the clearest systems in the world: the number is your foot length in centimetres. A JP 27 fits a 27 cm foot. That makes it easy to convert — match the cm to your US, UK or EU size below.
