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