How to Measure
Follow the instructions below and compare your measurements with the size chart
Foot length
Place your foot against a wall and measure the distance from the wall to the tip of your toes.
Manufacturers do not always use the same sizes for shoes. Therefore, we recommend using the foot length to find the correct size. The international standard for foot length is known as Mondopoint and indicates the size of the foot in millimeters (mm).
Tip! Use a soft measuring tape, to ensure that the product fits properly. Alternatively, use a piece of string and then measure it against a ruler
