injinji describe the Trail Midweight crew toe socks as: This is the sock for long runs and aggressive hikes on rugged terrain. Our toesock design minimizes friction between the toes to help eliminate blisters, frees them to splay naturally, and lets you utilize your whole foot on narrow, uneven trails. The crew length rides high to seal out debris, and a band under the arch adds support. COOLMAX® fibers and a mesh top keep feet dry and cool, nylon fibers add durability, and midweight cushioning protects your feet.
