Frequently Asked Questions
Q.How does foot length in centimeters map to US shoe sizes?
Each full US adult size corresponds to roughly 0.847 cm of foot length, meaning a 25 cm foot generally equals a US men's 7 or US women's 8.5 depending on the conversion table used.
Q.Why is there about a 30-unit gap between US and EU shoe sizes?
EU sizing uses the Paris point (two-thirds of a centimeter) while US sizing uses the barleycorn (one-third of an inch). The accumulated offset across the starting reference points creates the perceived 30-size difference.
Q.Does shoe width affect international size conversion results?
Global standards address length only. Width categories (narrow, standard, wide, extra-wide) follow brand-specific grading rules, so you still need a manufacturer's width chart for a complete fit.
Q.Are kids' shoe size conversions consistent between US, UK, and EU systems?
Kids' sizing is fairly standardized because growth increments are tightly regulated, but the transition point between toddler and youth categories varies by region, so always confirm with foot length in CM.
