Shoe sizes in South Korea

South Korea uses sizes that are the foot length in millimetres (KS M 6681), but brands print smaller US sizes beside them: on the charts of Crocs, Golden Goose and Onitsuka Tiger, 68 of 75 rows give a smaller US size than the standard’s.

By the standard, South Korea 260 fits a foot up to 26.0 cm: a men’s US 8.5–9, women’s US 10–10.5, UK 7.5–8, EU 40.5–41.

South Korea sizes on brand labels

Only three brands we track print South Korea sizes on their charts (Crocs, Golden Goose and Onitsuka Tiger), and 4 of the 62 US sizes they print beside them match the standard’s. Where more than one of them prints a size, they give it the same US size on 4 of 24 sizes. So each brand’s own US size is shown: find the size on your shoes and the brand you’re buying.

The standard (KS M 6681) makes each size for its own foot length and allows a foot up to half a step either side. Here, as in our calculator, a foot gets the first size at least as long as it, so a size fits feet longer than the size before it, up to its own length, so you never get a size shorter than your foot. Where that range spans more than one size elsewhere, all of them are shown.
