A NEW LEVEL OF TRACTION TECHNOLOGY. The new Vibram Arctic Grip All Terrain outsole with Vibram XS Trek Evo compound provides advanced traction on all terrains including wet ice snow mixed/loose surfaces and hard pack; superior grip no matter the season. The winter can be unpredictable but your footwear shouldn't be. That is why we've developed the Arctic Ice Mid with Arctic Grip. These winter high-performance sport boots step up the warmth factor with 5mm neoprene inner boot layered with cozy fleece lining for ultimate warmth in extreme conditions. The stretch-fit top-line binding keeps the boots snug to your legs to keep cold air out and warm air in.
