How to measure

Calf: sit with your knee bent at 90°. Wrap a soft tape around the widest part of your calf. If you'll wear jeans or leggings inside your boots, measure over them.

Foot: stand on a sheet of paper, mark your heel and your longest toe, and measure the distance between the two marks.

How to choose

Pick the size that matches your foot length. The boot calf width should be the same as your calf measurement or a little bigger. Between sizes? Go up half a size.

Shaft height: knee-high. Heel height: 3.1" (8 cm).
