More Information
Summary:A footwear article is provided. The footwear article includes a shoe sole. The shoe sole includes a crosslinked foam polyolefin elastomer having a density less than 0.88 g/cm3, the crosslinked foam polyolefin elastomer including: a silane-grafted polyolefin elastomer, a silane-grafted olefin block copolymer, a polyolefin elastomer (POE), an olefin block copolymer (OBC), or a combination thereof; an ethylene vinyl acetate (EVA) copolymer; a crosslinker; a condensation catalyst; and a foaming agent. The shoe sole exhibits a compression set of from about 1.0% to about 50.0%, as measured according to ASTM D 395 (48 hrs @ 50° C.).
