the present invention discloses a compound and a method for a cushion pad that is bonded to an outsole without the need for glue or other adhesives . this cushion pad can be softer and more flexible then the outsole but can be similar enough in composition to be recyclable without having to separate it from the outsole . the compound can consist of a styrene - butadiene - styrene triblock copolymer , ethyl - vinyl - acetate , peroxide , a filler agent , and a blowing agent . the combination of these materials will form a high rubber content foam sheet that is very soft and shock adsorbing . this process can use the above compound to manufacture a rubber outsole with an integrated cushioning pad that can be manufactured in one step .
