ABSTRACT:
There is disclosed a shoe with an internal warming mechanism which comprises an electrical resistance coil in the sole or upper coverings of the shoe, and with an electrical generation mechanism in the heel of the shoe which is driven by the up-and-down movements of the wearer's heel which accompanies normal activities such as skiing, hiking, etc. The electrical generator includes an armature mounted for rotational movement in a magnetic field and mechanically connected to a vertical post which is dependent on the undersurface of the heel portion of the inner sole of the shoe. The post is connected through a vertical spiral groove to a sleeve which is coupled with an escapement to a flywheel that is unidirectionally driven by the sleeve. The flywheel is coupled through a gear train to the armature of the electrical generator.
