How to measure your foot

  1. Place a sheet of paper flat against a wall on a hard floor.
  2. Stand on it, heel touching the wall, wearing the sock you'll use.
  3. Mark the tip of your longest toe.
  4. Measure from the wall edge to the mark in millimeters.
  5. Repeat for the other foot. Use the larger value.
