Calculate your own measurements, then select your product size

1. Place a sheet of paper on the floor and against a wall
2. Make sure you are wearing the same socks that you would normally wear with this type of shoe
3. Wearing these socks, stand on the sheet of paper with your foot perpendicular to the wall and your heel against the wall.
4. Then use a pen to draw a line just in front of your big toe. Repeat for both feet and take the longer distance to determine your size.
5. Using a ruler, measure the distance between the wall and the line you drew to find your size.
