Men's mountain boots are designed for use in the higher mountains and are therefore stiffer soled, often to accept crampons, with higher ankle protection and fully waterproof uppers, either in leather or synthetic materials. They're designed for better performance on rock, as well as snow and ice, than a walking boot.
