TREKKING socks with flat seams made of high quality materials and fibers that provide high comfort during long hikes. To reduce the moisture evenly, applied two vent panels (dorsum of the foot and tibia) that allow the skin to breathe during increased activity. This solution also protects the feet from excessive sweating and keeps them in the feeling of dryness. P> Places particularly vulnerable to damage (heel and toe) lined with an additional layer of material. This not only increases the strength of socks, but also absorbs part of the vibrations generated during the walk. Additionally, in the area of the metatarsal, ankle and shin placed special pullers stabilizing arrangement of the material on the foot. As a result, the sock does not move and does not slide during heavy walking, climbing or navigating the rough terrain.
