To find your right size, we recommend measuring your feet with these simple steps. First, place a sheet of paper flush against a wall and step on it with your heel touching the wall. Mark the longest and widest points of your foot, making sure to keep the pencil straight. Repeat the process for your other foot. Next, measure the distances between your marks in millimeters. You may find that one foot is longer than the other, which is quite common. In this case select the larger size. Our size chart accounts for toe room with a built-in allowance of approximately 5mm, so there is no need to add extra length.
