How to Measure

01

Foot Length

Stand on paper, full weight down. Trace the foot and measure heel to longest toe.

02

Foot Width

Measure across the ball of the foot at its widest point — standing, not sitting.

03

Both Feet

Feet are rarely identical. Measure both and fit to the larger one.

04

Break-In

New leather should feel snug, with room to freely move your toes.

Conversions are approximate. Fit may vary by last, leather and sock weight.
