Technical mountain functionality meets everyday urban winter use The award-winning Mountain Trainer 2 Winter boot offers an unbeaten combination of warmth, comfort and technical mountain functionality with aesthetic styling for everyday winter use and easier hiking trails. It blends mountain tradition with Salewa's innovative proprietary technologies. Suede & GORE-TEX construction The high-quality 1.4 mm suede and robust fabric upper has a GORE-TEX Performance Comfort membrane that is designed to provide waterproofing and optimised climate comfort in changing weather conditions and a wide range of activities. It protects your feet from rain, snow and slush, while allowing sweat in the form of water vapour to easily escape to the outside. Its four-layer laminate construction also offers a moderate level of additional insulation. The Salewa 3F System protects and wraps the foot for flexibility, fit and support and there is a full protective rubber rand and a stretch gaiter to keep out trail debris. Winter comfort For further winter comfort, the AlpineWool Flex Collar increases the range of motion of the ankle and insulates blood flow at the ankle and heel area, while the Salewa Responsive footbed promotes better thermoregulation and microcirculation. It absorbs and recycles far-infrared energy from the body and releases it back over time helping to keep your feet warmer for longer. Artic Grip Underfoot, the state-of-the-art Vibram Icetrek II sole with Artic Grip technology has wider lugs and a winter optimised rubber compound that offers unparalleled grip and performance in difficult conditions, like snowy surfaces and slippery, wet ice. This is the most advanced cold weather grip technology Vibram has ever created. A versatile hiking boot that will keep your feet dry and thermoregulated in winter conditions.
