How Shoe Sizes Convert Between Systems
Different regions use different sizing systems. US sizes are based on the Brannock device. EU sizes use the Paris point system (2/3 cm increments). UK sizes are similar to US but offset by about 0.5-1 size. Centimeters measure actual foot length.
Men's vs Women's Sizing
Women's US sizes are typically 1.5 sizes larger than men's for the same foot length. A women's US 9 equals a men's US 7.5. EU sizes are unisex and the same for both genders. UK sizes differ by about 0.5 between men's and women's.
Measuring Your Foot
Stand on a piece of paper and trace your foot. Measure from the heel to the longest toe in centimeters. Use this measurement to find your correct size in any system. Measure in the afternoon when feet are largest.
Tips for Buying Shoes Online
