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 carbon filter neutralizes unpleasant odors right from their source, and the latex underside of the sole provides a secure grip as the fourth layer. The perfect winter sole for a comfortable climate and cozy warmth in the shoe.
