How to choose your size. On a hard surface, tape a piece of blank paper to the floor and attach it flush against the wall. Stand up straight with your foot on the paper and heel against the wall. Mark the longest part of your foot (heel-to-toe length) and widest part of your foot on the paper with a pen or pencil.
Make sure your pen is held vertically, not at an angle. Repeat with the other foot, as right and left feet may be different sizes.
Use a ruler to measure the heel-to-toe length and width measurement for each foot. Based on your measurement, +810mm for Kids' size; +48mm for Adult Size.
