Modern M1917 Trench Boot in British Tan english bridle

ABOUT THIS COLLABORATION

The Trench Boot came out of World War I, developed when standard issue footwear proved inadequate for the conditions of the trenches. Built to endure mud, cold, and prolonged use, it laid the groundwork for how military boots have been made ever since.

This collaboration with Rose Anvil is a modern reproduction of that original. Every detail has been carefully considered, with small refinements made where wearability could be improved without compromising the intent of the design.

For this build, we worked with Hermann Oak, one of the oldest tanneries in the United States, to develop a version of their British Tan Bridle leather that is perfectly suitable for boots. 

THE LEATHER

Hermann Oak is one of the last vegetable tanneries in the United States to skip the pickling process, extending what is typically an overnight step into a week long tannage. The result is a leather with unusual depth, density, and long term character.

Bridle leather builds on that foundation. Heavily nourished with oils and waxes, it develops a natural pull up and grain variation that makes each side unique. With wear, it takes on a patina particular to how and where it is used.

For this collaboration, the leather has been further refined. Split to a lighter weight and dry milled for several hours to soften the hand, Hermann Oak also introduced a proprietary softening process specific to this build. The result is supple and approaches calfskin in feel, while retaining the structure and durability Bridle leather is known for.
