Warming aluminum sole

The high-tech Alu Therm Tech insole offers superior comfort and maximum protection against the cold thanks to its innovative four-layer construction. The first layer, made of wool fleece, warms the foot and ensures a comfortable climate inside the shoe, even in the lowest temperatures. The second layer, made of aluminum, acts as an intermediate layer, providing reliable insulation against cold and wet ground. An activated carbon filter layer neutralizes unpleasant odors as they develop, and the latex underside of the insole, as the fourth layer, offers secure grip. The perfect winter insole for a comfortable climate and cozy warmth inside your shoes.
