Great for linemen, loggers, dedicated ranchers, and other jobs where climbing is the norm, Carhartt® Climbing 8" Insulated Waterproof Composite Toe Work Boots for Men deliver secure footing and all-weather versatility. Insulated for warmth in cold weather, these rugged boots offer great support around and under your foot with an aggressive outsole that holds firm on slippery ladders and over uneven terrain. Made of tough, oil-tanned vintage saddle leather and abrasion-resistant Carstrong® fabric, the Climbing's uppers surround your feet and ankles in trustworthy support and protection. Lightweight composite toes up front meet ASTM F2413-18 EH workplace safety standards, while a TPU heel stabilizer with Achilles flex joint at the rear of the upper boosts ankle stability and heel protection. Storm Defender® waterproof/breathable membranes inside keep feet dry while allowing them to breathe. Advanced 600-gram LiteFire® reflective insulation reflects body heat and lets feet breathe to keep feet warm and comfortable in cold working conditions. A supportive boot design, the Climber merges Cushion Comfort polyurethane insoles with polyurethane Strobel pads, steel shanks, and rugged, super stable Goodyear welt construction to offer a cushioning, supportive base under your feet all day long. Meeting ASTM F3445-21 SR standards, the non-marking, slip- and oil-resistant WoodWorks rubber outsoles sport an aggressive ladder lock tread that sheds mud and holds firm on slippery ladders or terrain. Outsole and boot meets ASTM standards for secondary protection against incidental contact with electrical circuits of 18,000 volts or less under dry conditions. Average height: 8".
