Stand on a level floor with your heel up against the wall or straight edge.
Step 2
Place a ruler or measuring tape on the floor under your foot or alongside it, with your heel at 0cm.
Step 3
Measure the length of your foot from your heel to the end of your longest toe (yes, even if it's your second toe).
Step 4
Measure both feet and go with the length of your longest foot if they are different. If you are in between sizes, we recommend going for the larger size.
Step 5
