ABSTRACT:
A shoe sole assembly of a resilient material body portion provided with absorbers energy formed as part of the body portion. The energy absorbers are defined by vertically disposed, spaced apart cell members extending from an upper surface to beyond a lower surface of the body portion to provide a bounded space. Each cell member is formed of an hollow compartment extending in part for the thickness of the body portion with its length depending upon the sole profile, the first end of the respective compartments at the upper surface of the sole body portion is initially open ended; whereas a hollow protuberance structure is at the lower surface of the body portion to enclose each cylindrical compartment at a second end. The protuberances extend beyond the lower surface to form contact areas with the ground surface when the sole assembly is used as part of a shoe. The compartments are separated from one another by adjacent lands which at the upper sole surface provide define respective substrate areas for the disposition of an inner sole thereon, so to seal each cell member with a volume of air trapped in the bounded space of the compartment and associated hollow protuberance structure.
