The North Face Ice Storm 400 Boa II Gore-Tex Winter Boots - Men's

The Ice Storm 400 Boa II insulated boots from The North Face boast serious insulation and waterproof protection, making them well-suited for deep snow and cold conditions. Synthetic nubuck and nylon mesh uppers are lightweight, durable and flexible; plus, they resist water absorption. Boa Closure System® uses a continuous cable to wrap around feet, eliminating pressure points and offering a glovelike fit. With a simple crank of the tongue-mounted knob, you can quickly and evenly lace and unlace; system will not loosen and never needs retying. Seam-sealed waterproof, breathable Gore-Tex® inserts prevent water penetration while allowing moisture vapor out, so feet can stay comfortable. 400g PrimaLoft® Eco insulation ensures warmth and comfort in conditions to -40°F during active use. Extra-high collars with gusseted tongues keep out snow; heel loops aid in entry and exit. Dri-Lex® fleece collars and tongue linings help move moisture away from your feet. Removable footbeds feature AgION™ antimicrobial treatment for excellent odor protection. Injection-molded thermoplastic urethane shanks deliver torsional stability while reducing cold temperature conductivity. Dual-density EVA midsoles deliver all-day shock absorption and comfort. Winter Grip™ rubber outsoles with self-cleaning lugs ensure stability and traction on snow. Temperature-sensitive Ice Pick™ rubber lugs on outsoles harden when temps fall below freezing, providing extra bite into the terrain.
