Featuring a Premium Timberland waterproof leather upper, a composite safety toe, and Anti-Fatigue Technology, the rugged, side-zip True Grit work boots help keep feet dry, warm and protected, enabling you to focus on the job at hand. The slip-resistant, thermoplastic polyurethane lug outsole helps keep you grounded, and we've added an Anti-Fatigue Technology footbed for shock absorption and energy return and ExoSpine technology that offers enhanced durability with lightweight thermoplastic polyurethane construction for lasting structure, enhanced heel fit for all-day comfort, and abrasion-resistant “kick-off” backing for easy boot removal. The breathable, moisture-wicking lining with odor control treatment is made of ReBOTL material containing at least 50% recycled plastic.
