Frequently asked questions
- Are shoe size conversions exact?
- No, shoe sizing varies slightly by brand and last shape, so conversions are approximate industry-standard equivalents.
- Why do men's and women's sizes differ for the same length?
- Men's and women's shoe size scales use different numbering for the same foot length, so gender must be selected for an accurate match.
- What does CM mean here?
- CM is the foot length in centimeters, the basis many international size charts use.
