We designed our heavy-duty insulated Boondock manufacturing boots to provide industrial-grade protection from every angle. Starting with their Premium Timberland® waterproof leather upper with an internal waterproof, breathable membrane for maximum waterproof protection and resistance to blood-borne pathogens, we added 200 grams of insulation for cold-weather comfort and to retain heat, 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, and our Anti-Fatigue Technology footbed for all-day shock absorption and energy return. Remaining true to our commitments, their breathable, moisture-wicking linings are made of ReBOTL™ fabric containing at least 50% recycled plastic. You’ll also find protection from below with the All-Weather TPU outsole that is heat-resistant up to 120 degrees Celsius, as well as slip-, oil, and abrasion-resistant, non-marking, and offers enhanced traction in extreme environments.
