How to measure your foot length

Place your foot against a wall and measure the distance from the wall to the tip of your toes.

How to measure your foot length

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).

In the size chart we have converted Mondopoints into foot length in inches to make it easier for you to find your size :-)
