FAQ
Can I convert shoe size by formula only?
Formula conversions are useful for estimates, but shoe brands use different lasts and fit models. Foot length plus brand chart is safer.

JP shoe size usually follows foot length in centimeters, making it a helpful cross-check for international conversions.
Why do shoe size converters disagree?
They may use different assumptions for toe room, men/women offsets, half sizes, and EU rounding.
