1. In a foot warmer mechanism for a shoe having a heel with an open compartment and an outer sole and having an inner sole mounted within said shoe for relative vertical movement therein and with a mechanical translator located in said open compartment of said heel and mechanically linked to the reciprocal vertical movement of said inner sole and electrical generation means seated in said compartment within said heel and including a gearbox and a mechanically interconnected electrical generator and electrical heating means within said shoe in circuit to said electrical generator, the improvement comprising:

  • .a. a flywheel mounted for rotational movement on a vertical axis in the heel of said shoe and mechanically coupled through said gearbox to said electrical generation means;

    b. a sleeve coupled to said mechanical transducer also mounted in the heel of said shoe coaxial with said flywheel; and

    c. a resilient helical coil spring with its inner end secured to said sleeve and its outer end secured to said flywheel,whereby rotational movement of said sleeve is resiliently transmitted to said flywheel, and said spring absorbs the shock from impacts applied to said sleeve by rapid and forceful movements of said inner sole.
