1. Barefoot, stand on the sheet of paper with your heel against a straight wall. Do this in the evening, or the afternoon at least, once you’ve been on your feet for a while.
2. Mark the end of your foot with a pencil or by placing a piece of masking tape on the floor parallel to the wall.
3. Stand back up straight and check again. Adjust the tape if necessary.
4. Measure the length of your foot from the heel to your longest toe. Compare this measurement with the lengths (cm) in the size chart below.
