Description
The Diego men's 6" work boot is designed to provide unmatched durability and comprehensive safety features for tough work environments.

The outsole also handles heat exposure up to 130°C, ensuring reliability on hot surfaces. Made from premium full-grain leather, the boot includes a lightweight composite toe for essential protection without added weight. A waterproof membrane keeps your feet dry in wet settings, while the puncture-resistant footbed offers dependable defense against sharp hazards.
