Men's Danner Caliper Work Boots 98397-19457 Whether you're putting in long days in the machine shop, on a road crew or on the tarmac, sore feet make it harder to concentrate on the task at hand. The Caliper is designed for jobsite comfort and safety. The full-grain leather upper is strong and durable, but soft enough to wear right out of the box. The boot is constructed with four layers of cushioning underfoot to give you maximum comfort from clock-in to clock-out. Features Full-Grain Leather Upper: To ensure its quality, we put our leather through six different tests before making our selection. Our full-grain leathers are the strongest and most durable form of leather. Memory Foam Strobel Sock: The strobel sock, the material used to finish the bottom of a boot, is made from memory foam for additional comfort and cushioning underfoot. Aluminum Toe: Our aluminum toe meets or exceeds ASTM F2413-18 I/75 C/75 EH standards. Danner Caliper Outsole: The oil-and-slip-resistant rubber Caliper Outsole offers versatile indoor and outdoor traction with a low-profile 90° heel. Electrical Hazard Protection: Electrical hazard (EH) footwear is manufactured with non-conductive electrical shock resistant soles and heels. Danner Dry: 100% waterproof barrier allows moisture to escape without letting water in, keeping your feet dry and comfortable all day long. Men's Danner Caliper Work Boots
