To find your correct size, place your foot flat on the floor with your heel against a wall. Put a sheet of paper underneath and mark the tip of your longest toe.

Measure the distance from the wall to the mark — this is your foot length.

Then, check the size guide on the product page and choose the size that corresponds to your foot measurement, making sure the shoe length is at least 0.5 cm longer than your foot to allow natural movement and proper toe space.
