Step 1: Stand up straight on a hard surface with your heel against the wall and a piece of blank paper taped to the floor, flush against the wall beneath your foot.
Step 2: Have someone mark the longest part of your foot (referred to as heel-to-toe length) on the paper with a pen or pencil, or measure yourself if necessary. Repeat with the other foot, as right and left sizes may be different.
Step 3: Measure the longest part of your foot, taking the measurement from the back of your heel to the end of your big toe.
Women should add 6mm to this measurement to allow for movement and room when the boot is used, men should add 8mm.
This combined measurement will be your insole length, which you will find on all our size guides.
Step 1: To find your calf measurement sit down on a chair with your knee bent at a 90-degree angle and your foot flat on the floor.
Step 2: You will want to measure your calf at the widest part without pulling the measuring tape tight.
Step 3: Measure both calves, if there is a different in the measurement, we suggest going with the bigger for sizing.
