Lovely slipper socks with wool lining and polyester outside. Black, non-slip material under the entire sole. The wool feels soft and comfortable against the skin and breathes well. It transports sweat and moisture, and is naturally odor-inhibiting. From Safa of Norway - a company that specializes in base layer clothing made of wool.
