The Injinji Outdoor Nuwool Socks individual anatomic toe sleeves form a thin anti-blister membrane between toes to eliminate skin-against-skin friction. The Injinji Nuwool blend of merino wool, nylon and spandex wicks moisture to keep your feet dry when you're moving fast and light, hiking or on a winter adventure. Injinji Outdoor Nuwool Midweight Crew Socks have medium cushioning.
