Our liners are the ultimate baselayer socks. They quickly wick away moisture, and have an ultra-thin ergonomic fit that won’t bunch up or slip under your outer socks. The five-toe design forms to the contour of your foot, allowing for natural, restriction-free movement, and – with each toe separated – skin-on-skin contact between the toes is eliminated, helping to prevent blisters. Designed as liners, these ultra-thin crews also work as fast and light socks for warm weather hikes and runs.
