US men's shoe sizes are based on the barleycorn system (1/3 inch per size) with a zero point of 7⅔ inches. US men's sizes run approximately 6–16. US men's size 9 = UK 8.5 = EU 42.5 = 26.0 cm foot length.
US shoe sizes are gender-differentiated: the same foot length corresponds to different numbers for men and women. US women's sizes are approximately 1.5 sizes higher than US men's for the same foot length.
Interesting fact: Despite being the world's largest footwear market, the US has never officially standardized shoe sizes. Sizes are manufacturer-defined, which is why sizes vary between brands — a Nike 10 may fit differently than an Adidas 10.
CM (centimeters) shoe sizing directly measures foot length and is used in Japan and is the clearest international reference. It removes ambiguity from gender-specific or regional numbering by using actual physical measurement.
Japanese shoe labelling uses foot length in cm (e.g., 25 cm, 25.5 cm). This makes fitting straightforward: measure your foot length and add 0.5–1 cm for fit. CM sizing is also the most reliable cross-gender shoe size reference.
Interesting fact: Measuring foot length at the end of the day (when feet are at their largest due to swelling from walking) gives the best fit. Feet can differ in length by up to a full size — always fit to the larger foot.
Shoe sizes are not standardized internationally. EU sizes use Paris points (⅔ cm), US sizes use barleycorns (⅓ inch), and UK uses a similar scale with a different offset. US men's and women's sizes differ by 1.5 sizes for the same foot. EU sizing is gender-neutral. The most reliable approach: measure foot length in cm and consult brand-specific size charts.
Always treat size conversions as a starting point — sizes vary significantly between brands and shoe styles.
