How to Measure Your Feet

  1. Place a sheet of paper on a hard, flat floor.
  2. Stand on the paper while wearing the type of socks you normally wear with trainers.
  3. Mark the back of your heel and the end of your longest toe.
  4. Measure the distance between the two marks in centimetres.
  5. Repeat the process for your other foot.
  6. Use the measurement of your larger foot when choosing a size.

Between sizes? We recommend selecting the larger size. Fit can vary slightly depending on the brand, model, foot shape and preferred fit.
