Engineered to stand up to the challenges faced by Fire Fighters and First Responders, the ruggedly built Rocky S2V Predator Duty Boot wears comfortable in even the toughest conditions. PTFE coated full grain leather and 1000D CORDURA nylon make this boot fully flash-, fire-, abrasion-, and water-resistant, while advanced S2V Sieve technology lets air in and moisture out. Rocky's exclusive Air-Port cushioned insole and Dri-Lex moisture wicking liner are treated with AEGIS Microbe Shield block odor and harmful microbes, so your feet stay cool, comfortable, and dry. A Vibram outsole, Roll-Stop Ankle Stability, and full fiberglass shank provide maximum grip and stability on unpredictable terrain.
