How to Find Your Mondo Size
- 1 Stand on a piece of paper with your heel against a wall
- 2 Mark the tip of your longest toe on the paper
- 3 Measure from the wall to the mark in centimeters
- 4 This measurement is your Mondo size
Tip: Boots should fit snug but not painful. A slight heel lift is normal initially and will improve as the liner breaks in.
