Size & Fit Guide

Built Around the Calf, Not Just the Foot

Most tall boots are cut to one calf measurement and hope for the best. Every style in our Wide-Calf edit is cut with a roomier shaft from the start — no stretching, no forcing a zip, no gap where a lace or elastic panel takes over.

How to Measure Your Calf

Wrap a soft measuring tape around the widest part of your calf, standing with your weight evenly balanced. Keep the tape snug but not tight. Measure both legs — they're rarely identical — and use the larger number.

• Narrow fit: up to 35cm / 13.75in
• Regular fit: 35–38cm / 13.75–15in
• Wide fit (our core range): 38–43cm / 15–17in
• Extra-wide fit: 43cm+ / 17in+

Each product page lists the shaft circumference for that style so you can check it against your own measurement before ordering.

Shaft Height

Shaft height is measured from the top of the heel to the top edge of the boot. Knee-high styles typically sit just below the knee on an average 168cm/5'6" frame — shorter or taller than that, expect the fit to sit slightly lower or higher.
