Norrøna Senja Merino Lightweight Socks Long are long socks developed specifically for trail running, but also suited to all types of outdoor activities.

The socks are made from a combination of merino wool, polyamide, and elastane, providing outstanding temperature regulation, natural odour resistance, good durability, and a low level of friction.

They feature a technical fit with extra cushioning under the foot for increased protection, as well as a reinforced heel and toe area. A close-fitting band of merino wool with a natural curve keeps the socks securely in place.
