1. An improved shoe of the type having a flexible sole and having a heel and a toe and having at least one light-emitting diode in the sole thereof, said light emitting diode having a light emitting portion, a first conductor and a second conductor, said at least one light emitting diode being supported in the sole of the shoe so that the light-emitting portion thereof is visible from the exterior of the shoe, at least one wafer battery having a first surface and a second surface and a positive terminal on one surface and a negative terminal on the other surface, said at least one wafer battery being held by said shoe and electrically connectable to said first conductor and said second conductor of said at least one light-emitting diode when weight is exerted on the sole of said shoe, wherein the improvement comprises:

  • supporting said light emitting portion of said at least one light emitting diode so that the first conductor thereof extends in a cantilevered manner from said light emitting portion and is a cantilevered conductor and said cantilevered conductor is adjacent but not touching one of the terminals of said at least one wafer battery so that when weight is exerted over the cantilevered conductor by walking, the cantilevered conductor is moved downwardly into contact with said one of said terminals of said at least one wafer battery; and

    means for electrically connecting the second conductor to the other of said terminals of said wafer battery so that the circuit between the light emitting diode and the wafer battery is completed and the light emitting diode is energized when weight is being exerted over the cantilevered conductor and when the weight is removed over the cantilevered conductor, the natural elasticity of the cantilevered conductor will cause it to move out of contact with said terminal of said wafer battery thereby de-energizing the light emitting diode.
