The Smartwool Men's Run Zero Cushion No Show Socks may be out of sight, out of mind, but they're totally dialed in on every run. The no-show silhouette stays hidden in active footwear, while a sewn-in binder and internal heel gripper offers a secure, stay-in-place fit. Each pair is made with responsibly sourced Merino wool and enhanced with Indestructawool technology for added durability, and a Virtually Seamless toe for additional comfort. Plus, the 4 Degree Elite Fit System offers a performance fit with strategic stretch and mesh zones to promote breathability while helping protect against blisters.
