ÅPNE Circular & HUK Circular

Measure you feet by standing up straight on a hard surface with your heel against the wall. Put a piece of blank paper taped to the floor below your foot and have someone mark the longest part of your foot on the paper (or do it yourself if necessary). This is called ”heel-to-toe length”. Repeat with the other foot as left and right sizes might be different. Use a ruler to measure the heel-to-toe length you have marked on the paper. We recommend 0.5-1cm spare room for a comfortable fit.
