Foot length in centimeters is the one measurement in any shoe chart that doesn’t change by brand or country. Measure heel to longest toe, then use the tables below (or the tool) to find your US size — choose women’s or men’s first, since the same foot length maps to a different number in each.
Foot length in centimeters is the one measurement in any shoe chart that doesn't change by brand or country. Measure heel to longest toe, then use the tool above (or the tables below) to find your US size — women's and men's are genuinely different scales, so always pick the right one first.
Most guidance suggests about 1–1.5 cm of extra room past your bare foot length for comfort; the tool above leans toward the roomier neighboring size when your foot falls between two catalogue sizes.

A 24.5 cm foot is a US women’s 8 or a US men’s 6 — the two charts give different numbers for the identical foot length, which is exactly why picking the right chart matters.
Most guidance suggests about 1–1.5 cm of extra room past your bare foot length for comfort — the interactive tool on the main shoe converter already leans toward the roomier neighboring size when you’re between two.
Because US, UK, and EU size labels are assigned by each brand to a foot-length range, and brands don’t always agree on where those ranges start and end — the centimeter measurement itself is the only figure that doesn’t move.
