Frequently asked questions
What is KR 250 in US shoe size?
KR 250 (a 250 mm / 25 cm foot) is approximately US men's 7 and US women's 8. Because Korean sizing maps directly to foot length in millimetres, the US conversion changes between the men's and women's scales even though the KR number stays the same.
Why are Korean shoe sizes in millimetres?
It's the convention used across Korean retail and matches the Mondopoint system favoured for ski boots and athletic footwear, where the size is simply foot length in millimetres. KR 240 means a 240 mm (24 cm) foot, KR 265 means a 265 mm foot, and so on.
Are Korean and Japanese shoe sizes the same?
They use the same idea - size equals foot length - but a different unit. Korean sizes are in millimetres (e.g. KR 240), while Japanese sizes are in centimetres (e.g. JP 24). KR 240 and JP 24 describe the same foot.
