The Injinji Liner 2.0 Lightweight Crew Socks are designed to be worn as the first line of defense against excess moisture and blisters. Featuring a toesock design, they minimise skin-on-skin friction that leads to blisters and hotspots while letting your foot splay naturally for better alignment and comfort underfoot. Use them as a light first layer paired with a thicker outer sock, or wear them on their own in summer for everyday adventures, day hikes, and runs.
