Able to be used on their own in milder conditions or as liner socks when the weather hits hard, UphillSport “Ruija” Hiking L2 Socks are walking socks made using breathable, moisture-wicking Coolmax and a level of insulation to thermal grade 2 by providing a balanced temperature for feet. Ruija socks are named after a remote area of extreme cold by the Arctic Sea. To provide a perfect fit during trekking activities, these crew length socks have a 1x1 knit and are elasticated throughout, and the foot includes a fitted heel that adds comfort by keeping the sock in place. Smooth toe seams help to prevent chafing and blisters while walking.
