Black Diamond Rubber Fire Boots offer incredible comfort with stitched-down linings that don't pull out. And with their non-slip heels, they offer a better, more accurate fit, because the foot remains in place while working and walking. Plus they're coated with 9.5mm felt, which takes it easy on the feet. Other standard features include steel toes and shanks for added protection and lug outsoles for a better purchase on all types of terrain. Boots are also open cell foam insulated and meet or exceed NFPA 1971, ANSI Z41, and CSA Z195 requirements.
