AEROFORM SHELL Made of the same material used to insulate refrigerators and freezers, our polyurethane AeroForm Shell wraps the entire foot for cushioning comfort. Featuring 15mm of insulation over the top of the foot and 20mm underfoot for ultimate lightweight warmth. It is ultra-light and flexible and won't crack, tear or fade. ACTIVE FIT With a comfortable, secure fit to keep your foot in place while on the move, boots with Active Fit also go on and come off with ease. KICK-OFF HEEL PLATE For easy hands-free removal. POLYURETHANE SHIN Polyurethane reinforcement on the shin over the neoprene provides added durability. WINTER TREAD OUTSOLE Generous surface area helps this outsole grip on wet surfaces. NON-METALLIC TOE (NMT) & METATARSAL PROTECTION Our non-metallic toe does not transmit heat or cold and our AeroForm polyurethane shell wrapping the foot provides metatarsal protection. As expected, it meets or exceeds ASTM F2413-11 M I/75 C/75 Mt/75 EH standards. UNDERFOOT COMFORT Thick polyurethane midsole for best-in-class cushioning and insulation underfoot.
