Abstract
A new footwear, such as a shoe or boot, with heated sole for helping keep a wearer's foot warm, especially in cold weather. The inventive device includes a footwear member having a sole and an upper portion for accepting a foot. The heel of the sole has a cavity therein with the lower surface of the heel having an opening into the cavity. A heel door is pivotally coupled to the lower surface of the heel for substantially closing the opening into the cavity. An elongate heating coil is provided within the interior of the sole for providing heat to the footwear when powered. Disposed within the cavity of the heel is a power source electrically coupled to the heating coil to provide power to the heating coil.
