HOW TO FIND YOUR SIZE?

#STEP 1: MARK

Place your foot on a piece cardboard or paper. Draw a horizontal line at the back of your heel and your longest toe.

#STEP 2: MEASURE

Measure the length between the two horizontal lines.

#STEP 3: MATCH

Match your measurements to our size chart above and find your perfect size. If you are between sizes then choose the bigger size.
