I purchased these Kamik insulated boots at the beginning of winter 2016 and have now worn them through two winters. These boots have a nice soft lining that has kept my feet warm and and the waterproof material the boots are made of kept me dry during the Upstate NY winters. While they are very warm and comfortable they are a little clunky. Perfect for shoveling,snow blowing,or walking through the snow, but would not be the most practical for winter sport activities or hiking.
