How to measure your foot length:
  • 1. Place a piece of paper against a wall.
  • 2. Stand on it with your heel against the wall.
  • 3. Mark where your longest toe ends (both feet).
  • 4. Measure from the edge of the paper to both marks in centimeters.
  • 5. Use the longest foot measurement and match it up to our size chart.
