About the Shoe Size Converter
This shoe size converter shows your size in the US, UK and European systems plus the foot length in centimeters. Men’s, women’s and kids’ sizes use different scales, even within the US, so pick the right type first. It is handy for ordering shoes from European or Asian shops or for buying shoes while traveling.
The charts follow the sizing used by major athletic brands such as Nike. Brands and models can differ by about half a size, so check the brand’s own chart when in doubt.

How to measure your feet
Measure in the evening, when feet are slightly larger. Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe and measure the distance. Measure both feet and use the longer one. Most people need about 0.4 in (1 cm) of room in front of the toes.
