FAQs
How is Japanese sizing more precise?
Direct foot-length cm. No country-conversion math. Measure your foot in cm, that's your size. Japanese shoes labeled 26.5 are designed for a 26.5cm foot — no ambiguity.
Width in Japanese sizing?
Japan uses E, EE, EEE, EEEE for width (E narrow → EEEE wide). Most stock shoes are EE width. Wide-foot shoppers should look for 3E or 4E labels.
