JP size = foot length in cm. JP 27 fits a 27 cm foot. Japanese brand charts pair each length with a slightly smaller US number than US retailer charts do, so when buying Japanese brands, trust the cm figure.
This Japanese shoe size converter translates Japanese JP shoe sizes to US, UK, and EU. Japan uses the JIS standard sizing system where the size number equals your foot length in centimeters. JP 26 means a shoe for a foot that measures exactly 26 cm. This makes Japanese sizing one of the most logical in the world. It is used by Asics, Mizuno, New Balance Japan, and Onitsuka Tiger on Japanese market products.
