Frequently asked 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.
