The men's IMPACT Boots by Baffin are insulated all-cold-weather boots with multi-layered inner boot systems made for comfort in our polar extremes. An Arctic Rubber shell and Polar rubber outsole buffer plenty of warming properties you can count on. Double B-Tek insulation and a waffle-comb footbed trap heat and keep it inside. The upper is waterproof and Diamond-Lite insulated. Double aluminum insoles protect your foot from the cold underneath.
