Articles of footwear including sole structures and rand

An article of footwear comprising:

• an upper;
• 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 and ground-contacting, wherein a length of the plate is configured to extend from a toe region to a heel region of the article of footwear;
• and
• a rand comprising a rand polymeric material that is different from the first polyolefin resin;
• wherein the rand is operably coupled to at least a portion of the perimeter of the plate and at least a portion of the upper,
• 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 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 is 5 percent to 30 percent by weight based upon the total weight of the resin composition;
• and
• the rand polymeric material comprises a polystyrene, a polyethylene, an ethylene-α-olefin copolymer, an ethylene-propylene rubber (EPDM), a polybutene, a polyisobutylene, a poly-4-methylpent-1-ene, a polyisoprene, a polybutadiene, an ethylene-methacrylic acid copolymer, a copolymer thereof, or a blend or mixture thereof.
