Our liner toe socks are the ultimate base layer socks. Quickly wicking away moisture, and with their ultra-thin fit that doesn't bunch up or slip under your outer socks, they are perfect for a stand alone sock or as a base layer. 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.
