Very good socks which reliably nestle at the foot. Good quality and moisture management tested in a one-week walking holiday with 4000hm and 55km length most often in the snow. Unbeatable for heavy leather boots because they can breathe only with difficulty together with the Rohner Trekking original, but offer the ultimate in support and protection of the feet. So every day makes in jedwedem weather in the mountain fun from beginning to end.
