摘要：
A shoe sole and heel integrally molded of an elastomeric material having a filler of hollow glass spheres dispersed therein. The spheres are mixed with the elastomeric material prior to molding. The resulting composition is injection molded in the shape of a heel and sole directly on the bottom of a shoe upper to form a lightweight, relatively inexpensive and wearresistant shoe bottom.
