When you leave the groomed trails to make your own set of tracks this winter, make sure the Alpina T20 Plus Touring Boot is laced up on your foot. The Hinged Plastic Cuff gives you the necessary support to tackle extended trips into snow-covered landscapes while the Alpitex waterproof membrane and Thinsulate insulation keep your toes warm and dry each stride of the way.
