Great for farm work and other mucky work conditions, the waterproof 15" ChoreMaster Plain Toe Boot is designed with Irish Setter's patent-pending ExoFlex technology for a secure and comfortable fit. The ExoFlex design accommodates the back of the foot while slipping the boot on and off, but contracts for a lock-tight fit once your foot is in place. The flexible top is made from fully-waterproof 4.5mm neoprene, while the Chore Sole is slip-resistant, oil-resistant, chemical-resistant, abrasion-resistant, and heat-resistant. This rugged boot is designed with a steel shank, Vulcanized construction, and a removable polyurethane footbed for comfort and durability. 15" high. Rating: ASTM F2892-11, EH.
