Size Guide
How to Find Your Size
- Stand on a flat piece of paper with your heel against a wall.
- Mark the tip of your longest toe and the back of your heel.
- Measure the distance between the two marks in inches or centimeters, then find your size below.
Your usual size is a starting point. If you are between sizes or prefer a roomier fit, choose the larger size. Foot length is the most accurate way to find your fit.
