Size

Struggling to decide between sizes? Our size charts offers a solution for those who are in between sizes, by suggesting to go down a size for a tighter fit or up a size for a more relaxed fit.

Find your perfect fit with these easy steps:

For the most accurate measurement, measure your feet at the end of the day.
Place a piece of paper on the ground, and stand on it with your heel against a wall.
Mark the end of your longest toe on the paper, and measure the distance from the wall to the mark.
Repeat this process for the other foot and compare the measurements to our size chart to determine the correct size.
