Footwear sole
In aspects of the invention, a footwear sole can include a sole member formed of a single unitary layer, wherein the sole member is formed of a compound including ethyl vinyl acetate (EVA) and rubber. The compound can further include a bulking agent. The compound can further include a foaming agent, a color master agent and a bridging agent. The sole member can include a top surface, the top surface including a plurality of apertures defined in a rear portion of the top surface. The plurality of apertures can define a tapered shape, and a first aperture of the plurality of apertures can have a depth that is less than a second aperture of the plurality of apertures. The plurality of apertures can be arranged in a plurality of rows.
