FAQ
Why doesn't my brand match exactly?
Shoe sizing isn't perfectly standardized — brands round differently and use slightly different lasts (the foot-shaped mold shoes are built on). Treat this as a solid starting point, and check the specific brand's own size chart when possible.
What does the foot length column mean?
It's the measured length of the foot in centimeters that the size is based on — useful if you've measured your foot directly rather than starting from a known size.
Why do men's and women's sizes differ at the same foot length?
Men's and women's shoes typically use different width and volume proportions even at the same length, and the numbering systems themselves are offset by convention (a women's US size is roughly 1.5-2 sizes higher than the equivalent men's size).
