EcoSox thermal socks help keep you warm in the winter by keeping your feet dry by pulling moisture away and allowing it to evaporate which helps regulate temperature.

Most EcoSox thermal socks are made with viscose fibers derived from sustainable and eco-friendly bamboo that are as soft as silk and as dry as a desert.  Along with an arch support that helps fight fatigue and keep the sock in place,  most models offer a padded foot for enhanced comfort.  Wear a pair of EcoSox and feel your feet smile!
