How to Measure Your Foot
Wear the socks you’ll use with the boots. Sit with knees at 90° and trace your foot on paper.
Measure in the evening for best accuracy.
A. Foot Length and Width
Use a ruler to draw two lines: one from heel to longest toe, and one across the widest part of the foot.
Measure both feet and use the larger one as reference. Avoid measuring in the morning.
