We designed our heavy-duty Boondock manufacturing boots to provide industrial-grade protection from every angle. Starting with a Premium Timberland waterproof leather upper with an internal waterproof, breathable membrane for maximum waterproof protection and resistance to blood-borne pathogens, we added our molded Timberland PRO rubber toe protector that's as thick as a standard boot outsole and backed with a composite safety toe, a rigid external heel cup to support lateral movement, our Anti-Fatigue Technology footbed for all-day shock absorption and energy return, a breathable, moisture-wicking lining made of ReBOTL material containing at least 50% recycled plastic, and an antimicrobial treatment for odor control. You'll also find protection from below with our lightweight, all-weather TPU outsoles that are heat-, slip-, oil, and abrasion-resistant, non-marking, and offer enhanced traction in extreme environments.
