How to Measure
If you are unsure which shoe size to purchase, please follow the below steps:
- Trace the outline of each foot on a piece of paper.
- In a straight line from the middle of the heel to the longest toe, measure the length of each foot.
- If one foot is longer than the other, take the larger measurement and compare to the chart above.
- Foot length will determine your shoe size - round up or down to the closest size within 2 mm.
