Frequently Asked Questions
- How accurate are shoe size conversions?
- Shoe size conversions are approximate. Sizes can vary between brands, styles, and even individual shoes. Always try shoes on when possible.
- What does CM (JP) mean?
- CM refers to centimeters, the Mondopoint system used in Japan (JP). It measures your actual foot length in centimeters.
- Are men's and women's sizes different?
- Yes. A women's US 8 is not the same as a men's US 8. Women's sizes are typically about 1.5 sizes larger in US numbering for the same foot length.
- How do I measure my foot in CM?
- Stand on a piece of paper, mark the heel and longest toe, then measure the distance in centimeters. This gives you your CM/JP size.
