Socks are not the same socks. Through leisure activities and everyday use there are socks that have to meet higher demands. This is where functional socks come into play. Different, high-quality materials are used here combined with elaborate knitting technology. Modal wool, merino wool and Coolmax fibers are, for example, high quality yarns that are added to the functional socks. Depending on the sock model, they provide pleasant warmth in winter and cooling on warm days. Functional socks can be warm and breathable thanks to the elaborate knitting technique. Merino wool, for example, absorbs no odors, has an insulating effect and dissipates moisture. The Coolmax fibers have a breathable, antibacterial and cool the foot at the same time. Tip and heel are reinforced on most models, so the longevity of the socks can be guaranteed. The outer layer of functional socks serves as a protective layer and is designed to guarantee fit and durability.
