The Liner 2.0 Lightweight Crew features a toesock design for blister protection and freedom. Constructed with NüWool™ for odor resistance and thermoregulation, this is the liner for long treks and ambitious day hikes.

Injinji's patented five-toe design conforms to your foot for a streamlined fit that rides comfortably under an outer sock, wrapping a layer of NüWool™ around each toe to prevent the skin-on-skin friction that leads to blisters. Soft and superlight, it is also great on its own for summer adventures.
