Born out of the same lightweight mountaineering design used for our Mountain Extremes, we built our Wildland Fire Boots for a singular purpose: To keep firefighters on their feet through brutal conditions, without having to worry about boot failure. We started with the heat and flame tested K-73 Fire, high traction, deep lug outsoles, utilizing Kevlar Hot Zone stitching and laces, on fire resistant 10� full grain leather uppers that mold to your feet. The result is unwavering support, Kenetrek�s renowned durability and all day comfort. Meets all NFPA 1977 Standard Requirements on Protective Clothing and Equipment for Wildland Fire Fighting 2016 edition. 4.2 lbs. Made in Italy.
