Size Guide:
- Place your heel against a wall and place a ruler or measuring tape on the floor with the starting point aligned with your heel. Measure the length of your foot from the heel to the tip of your longest toe.
- After measuring your actual foot length, add 1–1.5 cm for comfort while running.
- Compare the resulting length to the size chart above. Refer to the CM column and select the size corresponding to your adjusted foot length.
PRO TIPS:
- Measure your feet in the evening when they are at their largest, as this will provide a more accurate measurement.
- If one foot is slightly larger than the other, choose the larger size for comfort.
