Kids' Footwear Size Chart

Find your shoe size

Use a ruler to measure the length of your foot, from your longest toe to the back of your heel. Take the longest measurement and add a few millimetres for comfort or socks (which may be thick if you’re choosing hiking boots). Then look up your size in the size chart. Please note that footwear sizes differ between brands.
