Wear the typical type of socks you’ll wear with your sneakers, and stand up straight with your heel against the wall. Measure the longest part of your foot (heel to toe length) and compare the measurement to this sizing chart. Same with width measuring the largest part of your foot.
Our sweater is of regular size : you can pick the one you’re used to.
If you hesitate, take a sweater that fits you well, put it on a table and, without stretching it, measure its dimensions in centimeters. Compare them with our table of measurements below.
