These Thorogood firefighting boots are built to let you keep your mind on your work rather than worrying about your footwear. These fire boots have cushioned shin guards to minimize bone-jarring accidents and puncture-resisting stainless steel midsole plates to protect against jagged objects littering your environment. A tough steel triple ladder shank gives you extra support on uneven surfaces to decrease the chance of falling. You get even more protection as the Thorogood boots are rated for electrical hazards (open circuits up to 600 volts), and they're also waterproof and blood-borne pathogen compliant. Outsole: Flame / heat resisting "Traction Lug". Material: Rubber, Polyurethane.
