We designed our heavy-duty insulated Boondock Boot to provide industrial-grade protection from every angle. Starting with a Premium Timberland® waterproof leather upper with an internal waterproof, breathable membrane for maximum protection and resistance to blood-borne pathogens, an internal metatarsal guard, and we added 200 grams of insulation for cold-weather comfort and to retain heat. A molded TPU toe bumper is crafted to be as thick as a standard boot outsole and backed with a composite safety toe, paired with a rigid external heel cup to support lateral movement and our Anti-Fatigue Technology footbed for all-day shock absorption and energy return. You'll also find protection from below with our fabric puncture resistant sole plate and a lightweight, All-Weather TPU outsole that is heat-, slip-, oil, and abrasion-resistant, non-marking, and offers enhanced traction in extreme environments. The boot is complete with a breathable, moisture-wicking lining made of ReBOTL™ material containing at least 50% recycled plastic and an antimicrobial treatment for odor control.
