      How Japanese shoe sizes work

      • Japan's shoe standard (JIS S 5037) sizes shoes by foot length: from the back of the heel to the tip of the longest toe, in centimeters, in 0.5 cm steps.
      • The width code (A, B, C, D, E, EE, EEE, EEEE, F, G) comes from the girth around the ball of the foot for each length. Men's go from A to G, women's from A to F, children's from B to G.
      • There is no official table that turns US, UK or EU shoe sizes into Japanese sizes. Even ISO calls such conversions a guideline, and sites disagree by up to about 2 cm. Measuring your foot is the reliable way.
