A sole structure for an article of footwear, the sole structure comprising: - a plate comprising a first polyolefin resin, the plate having a first side and a second side and a perimeter, wherein the first side is configured to be ground-facing when the plate is a component of an article of footwear; and - an edge portion comprising a second resin that is different from the first polyolefin resin, the edge portion disposed on at least a portion of the perimeter; wherein the first polyolefin resin comprises a resin composition comprising: - a polypropylene copolymer, which is a random copolymer of ethylene and propylene having an ethylene repeat unit content of 1 percent to 5 percent based on the total weight of the polypropylene copolymer; and - an effective amount of a polymeric resin modifier, which is a copolymer comprising isotactic propylene repeat units and ethylene repeat units having an ethylene repeat unit content of 10 percent to 15 percent by weight based upon a total weight of the polymeric resin modifier, wherein the effective amount of the polymeric resin modifier is from 5 percent to 30 percent by weight based upon a total weight of the resin composition; and wherein the second resin comprises a polymeric component that is substantially similar to the polymeric component of the first polyolefin resin, except the polymeric component of the second resin comprises a greater concentration of the resin modifier than the polymeric component of the first polyolefin resin. - a plate comprising a first polyolefin resin, the plate having a first side and a second side and a perimeter, wherein the first side is configured to be ground-facing when the plate is a component of an article of footwear; and - an edge portion comprising a second resin that is different from the first polyolefin resin, the edge portion disposed on at least a portion of the perimeter; wherein the first polyolefin resin comprises a resin composition comprising: - a polypropylene copolymer, which is a random copolymer of ethylene and propylene having an ethylene repeat unit content of 1 percent to 5 percent based on the total weight of the polypropylene copolymer; and - an effective amount of a polymeric resin modifier, which is a copolymer comprising isotactic propylene repeat units and ethylene repeat units having an ethylene repeat unit content of 10 percent to 15 percent by weight based upon a total weight of the polymeric resin modifier, wherein the effective amount of the polymeric resin modifier is from 5 percent to 30 percent by weight based upon a total weight of the resin composition; and - a polypropylene copolymer, which is a random copolymer of ethylene and propylene having an ethylene repeat unit content of 1 percent to 5 percent based on the total weight of the polypropylene copolymer; and - an effective amount of a polymeric resin modifier, which is a copolymer comprising isotactic propylene repeat units and ethylene repeat units having an ethylene repeat unit content of 10 percent to 15 percent by weight based upon a total weight of the polymeric resin modifier, wherein the effective amount of the polymeric resin modifier is from 5 percent to 30 percent by weight based upon a total weight of the resin composition; and wherein the second resin comprises a polymeric component that is substantially similar to the polymeric component of the first polyolefin resin, except the polymeric component of the second resin comprises a greater concentration of the resin modifier than the polymeric component of the first polyolefin resin.
