  • Patent number: 6897167
    Abstract: The thermal foot cover is an article of footwear to be worn when the wearer's foot is subjected to cold temperatures. The thermal foot cover has an upper cover portion attached to a bottom panel to define a cavity for insertion of a wearer's shoe-encased or boot-encased foot or a wearer's foot. The upper cover portion and the bottom panel are made from a material comprising an outer covering, a radiant barrier and a inner covering where the radiant barrier is sandwiched between the outer cover and the inner cover. The radiant barrier is the insulation system of the thermal foot cover, which reflects the wearer's body heat back inside the footwear and keeps the wearer's feet warm. The thermal foot cover is flexible, lightweight and readily washable due to the use of the radiant barrier as the insulation system.
