- For rubber boots
The felt sock is a warm inner slipper for rubber and other boots. Also great as a home slipper. The cover of the sock is made of soft polyester-reinforced cotton, which absorbs itself and evaporates the moisture generated in the felt. The inside is a polypropylene felt that insulates well. The felt sock keeps the foot dry and warm. The product is vegan, ie it does not contain materials of animal origin.
