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.
B. Calf – measure the widest part
C. Height – from floor to the crease behind the knee
