To find your size, we recommend you measure your feet using a flat ruler or measuring tape and a wall. To measure your foot, place the ruler flat on the floor, with the end against a wall. Stand with your heel gently against the wall and toes pointing forward. Measure from the wall to the tip of your longest toe and record the length.

Measure both feet, and if there's a notable difference, go for the larger size. Once you have the length of your foot in centremetres, use the conversions below to find your Green Shoes size below.

If you are having a custom-fit, we recommend sending us foot drawings too. Stand on a blank piece of paper and get someone to trace around your feet for you (as you need to remain upright!), and then note the measurements for both the length and the widest part on each foot.
