Collonil Alu Therm Tech

The high-tech sole Alu Therm Tech offers maximum comfort and optimal cold protection through its highly innovative 4-layer construction. The first layer made of wool fleece warms the foot and ensures a pleasant shoe climate even in the lowest temperatures. The second layer made of aluminum serves as an intermediate layer and reliably insulates against ground cold and moisture. A layer of activated charcoal filter neutralizes unpleasant odors right from their source, and the latex underside of the sole provides secure grip as the fourth layer. The perfect winter sole for a comfortable climate and cozy warmth in the shoe.
