How to Measure

Measure the length of your foot by standing on a flat surface with your full weight on your foot, then measure the distance from the back of your heel to the tip of your longest toe.
Add 10mm to your foot length to allow your foot room to move.
Measure the width of your foot across the broadest point.
Compare your foot width measurement to the size chart in your size to see if you need a narrow or regular width.
