❓ Common questions
- Why are men's and women's sizes different?
- Men's and women's shoe lasts (foot forms) differ in width and shape. A women's size is typically 1.5 sizes larger than the equivalent men's size in the US system.
- Are EU sizes the same for men and women?
- EU sizes are nominally unisex, but men's EU 43 and women's EU 43 may differ slightly in width. The conversion offsets account for the US size difference.
- How accurate is the CM conversion?
- The CM value is approximate. Foot length is the most reliable measurement — measure from heel to longest toe and add about 0.5–1 cm for comfort.
- What about half sizes?
- Half sizes are fully supported. Enter 9.5, 10.5, etc. EU sizes are typically in whole numbers, so the result may be rounded.
- Do sizes vary by brand?
- Yes — sizing can vary significantly between brands and countries. Always refer to a brand's specific size chart for the best fit.
