This unique two-sock running system delivers exceptional blister prevention, moisture management, total foot utilisation, and cushioning. Layer one is our ultra-thin liner. It forms to your foot and features our patented five-toe design to protect you from blisters and leverages COOLMAX® fibers to quickly wick away moisture. The seamless outer sock is specially designed to layer over the liner. It provides underfoot cushioning, ventilation, and arch support. The Liner + Runner’s ergonomic design moves with your foot, and its mini-crew height seals out dirt and debris. Available in women’s and men’s versions, the Liner + Runner system is sold as a set.
