The women's Smartwool Run Zero Cushion Low Ankle Sock gives you comfort and durability that will help make every mile feel good. These lightweight running socks are made with Merino wool and recycled nylon for the perfect combination of temperature regulation, moisture control and odor control. Smartwool’s 4 Degree™ elite fit system eliminates sock slippage, bunching and prevents blisters, while mesh zones and a seamless toe keep your feet cool and comfortable. Plus, the Run Zero Cushion Low Ankle Socks were built to last thanks to Indestructawool™ technology that has extended durability zones and Shred Shield™ technology that reduces wear from the toes. With a low ankle height that helps you feel fast and an Achilles tab to prevent the sock from slipping into your running shoes, the Smartwool Run Zero Cushion Low Ankle Sock has everything you need for a great run.
