The Smartwool Run Zero Cushion Mid Crew Sock will be your favorite pair to reach for whether you’re hitting the trail, the pavement or the treadmill. 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 Mid Crew Socks were built to last thanks to Indestructawool™ technology with extended durability zones and Shred Shield™ technology that reduces wear from the toes. With a mid-crew height that gives you extra coverage and keeps pesky pebbles from sneaking in, the Smartwool Run Zero Cushion Mid Crew Sock has everything you need for a great run.
