Choose the right size
Doubt about the right size? No problem at all! The size chart below can be used as a guideline for choosing the right shoe size.
The best time to measure your feet is at the end of the day. Because of the warmth and movement your foot swells a bit during the day.
Do you fall exactly between two sizes? Then we advise you to always choose the bigger size. If this size turns out to be too big, you can always return the shoes free of charge!
