De Niro Official Size Guide

De Niro riding boots are sized with three measurements: foot size (EU), shaft height, and calf width. The resulting code is in the format foot/height/calf (e.g., 39/C/M).

How to measure (official De Niro method)

• Foot: Use your EU size.
• Height: From the ground to the hollow of the knee, with the leg slightly bent.
• Calf: Circumference at the widest point, with the tape snug.

Shaft height categories

De Niro uses four heights: Short (C), Medium Short (MC), Medium Tall (MA), and Tall (A). The knee circumference of a standard size is 2 cm smaller than the calf. When worn, the boot drops approximately 1–2 cm.
