The Bootdoc Heat Socks Surround with an integrated, larger heating element are anatomically shaped in the toe area. During development, special attention was paid to the heat distribution in the area of the big toe. The Surround Heat Technology warms the toe area pleasantly from all sides. The extremely fine fibres of the processed yarns ensure an optimal foot climate and have a breathable and moisture-regulating effect. Great care was taken to ensure fit and the highest wearing comfort: Thanks to gentle compression and wrinkle-free fit and intelligent cable placement, pressure points are avoided.
