The Smartwool Women's Run Zero Cushion No Show Socks are built for runners who want the closest possible connection to their shoes. Designed with zero cushion, they create an ultra-light feel that keeps distractions to a minimum mile after mile. Responsibly sourced Merino wool helps manage moisture and temperature, keeping feet comfortable through warm ups and cool downs alike. Indestructawool(TM) technology reinforces high-wear zones for dependable durability, while the Virtually Seamless(TM) toe reduces friction for a smooth stride. A no show silhouette with an internal heel gripper ensures a secure fit that stays hidden and locked in throughout every run.
