Shoe Size Conversion — Frequently Asked Questions
Q1 How do US, UK, EU, and CM shoe sizes compare? ▾
US Men's sizes are typically 0.5 to 1 size larger than UK sizes, while US Women's sizes are roughly 1.5 to 2 sizes larger than Men's sizes. EU sizes use the Paris point system (1 point = 2/3 cm), while CM/Japan sizes directly correspond to foot length in centimeters.
Q2 How do you accurately measure your foot length at home? ▾
Place a piece of paper on a hard floor against a wall. Stand with your heel against the wall, trace the longest toe tip with a pencil held vertically, and measure the length from the paper edge to the mark in centimeters or inches.
Q3 What do shoe width letters (A, B, C, D, E, 2E, 4E) mean? ▾
B is standard width for women and narrow for men. D is standard width for men and wide for women. 2E (EE) and 4E (EEEE) represent extra-wide fittings.
Q4 Why do shoe sizes differ across brands? ▾
Shoe manufacturers construct shoes around proprietary wooden lasts with distinct toe box shapes, arch contours, and instep heights, causing slight sizing variances between athletic and dress shoes.
