How to Measure

If you are unsure which shoe size to purchase, please follow the below steps:

If you are unsure which shoe size to purchase, please follow the below steps:

  1. Draw a straight line longer than your foot on a piece of paper.
  2. Place the paper on a flat surface. Stand on the line with your heel and longest toe centered. If measuring a child's foot, it may be easier to hold the paper up to their foot.
  3. Place a mark on the line at the tip of the longest toe and at the back of the heel.
  4. Repeat steps above for the other foot.
  5. Measure the distance between the marks. Taking the larger of the two measurements, use the conversion chart to find your correct shoe size.
