How to Measure
Measure late in the day, when your feet are at their largest, wearing the socks you'll wear with the shoes. Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe, and measure from the wall to the mark in centimeters. Measure both feet and go by the larger one. US men's shoes come in a standard D width; if your feet are wide, look for 2E or 4E instead of going up half a size in length.
Notes
Brands drift from these conversions by half a size or more, and one maker's sneakers and dress shoes may not match each other. Check the brand's own chart when you buy from an unfamiliar label.
Frequently Asked Questions
US and UK sizing systems were standardized independently using different baseline measurements, so a given foot length corresponds to a US size that is roughly 0.5 larger than the equivalent UK size. The offset is consistent across most of the size range but can vary slightly at the extremes.
EU sizes use the same centimeter-based numbering scale regardless of gender, but a 'men's EU 42' and a 'women's EU 42' are typically built on different lasts (shoe forms) and won't necessarily fit the same foot — the size number reflects the shoe's last length, not a unisex fit guarantee.
Add roughly 1.5 to 2 sizes to your men's US size as a starting point, then confirm by foot length: find your cm figure on this chart and pick the women's size with the same cm value on our women's shoe size chart. Women's lasts are usually narrower through the heel and forefoot, so expect a snugger fit at the same length.
