HOW TO FIND YOUR MONDOPOINT SIZE
It’s easy enough. Stand on top of a piece paper with your heel against a wall and all of your weight pressed down upon the foot you are measuring. Then, draw a line at your big toe. Measure (in mm) the length of the paper to said line, and voilà! That’s your Mondopoint size.
You will want to measure both feet obviously, and size to the larger foot.
