These Heavy Socks are made for the mountains. They provide high-level insulation for the wellness of your feet during any winter sports activity. The sweat-wicking TBus™ Technology helps disperse excessive heat when your feet warm up and evaporates sweat when you're going hard. And the Enhanced Silver Fibre Technology provides insulation to help keep your temperature constant. At the same time, silver's anti-bacterial properties prevent the proliferation of bacteria, keeping your feet warm and odour-free.
