Size Guide

To measure your foot size we recommend you to follow these steps:

  1. Place a clean sheet of paper on the floor, preferably against a wall.
  2. Place your bare foot on this sheet of paper with your heel against the wall.
  3. Use a pen/pencil to put a mark on the sheet of paper where your foot ends at the front (infront of your furthest toe). If the sheet of paper is not against a wall, we recommend that you to put a mark on the sheet of paper behind your heel as well.
  4. Repeat this process for both of your feet as the length of both feet may differ.
  5. Measure the length of the marking to the end of the sheet of the paper. If you placed two markings (one infront of your toes and the other behind your heel), measure the length between these two points.
  6. Use the measurement of your longest foot to find your recommended size in the chart below.

Example: If the measurement of your longest foot is 28.1 cm (11.063 inches). We recommend the size 43 EU (10 US / 9.5 UK), as the length of your foot exceeds the length measurement of size 42 EU (9 US / 8.5 UK) and is closest to size 43 EU.
