How to Measure Your Shoes Size
Stand on a piece of paper with your heel against a wall. Mark the tip of your longest toe, then measure the distance from the wall to the mark in centimetres. Measure both feet — most people have one foot slightly larger — and use the longer measurement. Measure at the end of the day when feet are at their largest. This length maps directly to JP sizes and can be converted to any other system with our chart.
Understanding US and KR Sizing
The US sizing system is the standard in the United States and is used by most American brands. US sizes are typically numbered and can differ significantly from European or Asian systems. Most US retailers display sizes prominently on labels and online, but the underlying measurements (in inches or centimetres) vary between brands, so treating US sizes as approximate is safest.
Korean (KR) shoe sizes are expressed in millimetres of foot length — so a KR 270 means a foot length of 270 mm (27 cm). This system is used across South Korea and is straightforward once you know your foot length. Korean clothing sizes use a mix of S/M/L labels and numbered chest or waist measurements.
Tips for Converting Men's Shoes Sizes
Korean shoe sizes are in millimetres — a KR 270 means 270 mm (27 cm). To convert from US, find the corresponding centimetre length and multiply by 10.
South Korean shoe shopping sites display KR sizes by default. If you order from platforms like Coupang or Musinsa, use our chart to avoid returns.
Sizes vary between brands — a US 10 in Nike may fit differently than a US 10 in Adidas. Always check the brand's own chart when buying online.
If you are between sizes, size up for athletic shoes (you need room for swelling during exercise) and consider sizing down for formal shoes (leather stretches over time).
Width matters as much as length. Some brands offer wide (W) and narrow (N) options. If standard-width shoes feel tight across the ball of your foot, try a wide version rather than going up a full size.
