Steigen Running Socks are designed to feel like your not wearing socks at all! Athletic or Running Socks are an accessory for comfort and the less you feel them the better. Steigen running socks are thin which creates minimal space between the shoe and your foot. This then leads to less movement in the shoe and then less fiction/heat. Steigen Running Socks are designed to create an environment in which blisters are less likely to form. They are designed to give the wearer a more responsive feeling from foot and shoe.
