Experience the double-layer, anti-blister system of WrightSock(TM) for friction-free, Coolmesh? performance.
Keep your feet cool and comfortable with these tab-back socks that are the lightest and most breathable two-layer socks available from Wrightsock. Interaction between inner and outer layers absorbs friction and shearing forces to prevent blisters. Inner layer of moisture-wicking Dri-WRIGHT™keeps feet dry; outer layer of Dri-WRIGHT and mesh weave maximizes moisture control and airflow. Mesh panel across the top of the foot allows maximum wicking action, keeping you drier and cooler than other socks. Inner layer is smooth and undyed, with a hydrophobic surface against the foot; tab back keeps socks from slipping down heels. Inner layer fabric content: 70% polyester and 30% nylon. *Offer not valid for sale-price items ending in $._3 or $._9.
