Abstract
Footwear includes a light source housed in a forward tip recess of the sole, and a push-bottom switch is mounted in a recess within the back contour of the heel for activation manually by tapping the back of the heel against a stationary object. A battery compartment is formed in an enlarged portion of the recess. A curved, focused lens contoured to the outer configuration of the sole tip is releasably connected over the frontal opening of the battery compartment. A releasably connected bulb-mounting assembly is interposed between the lens and the battery compartment. The sole includes a thin bottom layer, a thick central layer having front and back cut-outs defining the recess and a top layer supporting a foot strap.
