You wear the Injinji Liner Crew Nuwool Charcoal (grey) as your first layer of protection against excess moisture (sweat) and blisters. These liners keep your feet dry, comfortable and cool.
The NuWool version of these socks was made with Merino wool, the finest wool in the world. The unique structure of this wool provides perfect insulation. As a result, this NuWool Liner provides warm feet in the winter and fresh feet in the summer. The good moisture absorption of the NuWool ensures that your feet stay nice and dry.
The Injinji Liner Crew Charcoal is a lightweight, breathable and versatile toe sock. You wear them as a first layer, combined with a thicker warm outer layer. And in the summer you just wear them as a nice fresh, everyday toe sock.
Please note: NuWool is incredibly good at sweat absorption and thermoregulation, but is a slightly less sturdy fiber than the synthetic Injinji socks. This liner is therefore only suitable as a liner (i.e. under another sock), or as a casual sock. (And therefore not as a hiking sock without an extra upper layer!)
