1. A component for an article of footwear, wherein the component comprises a crosslinked and foamed composition, wherein the crosslinked and foamed composition comprises resin components, wherein the resin components comprise:
a partially hydrogenated thermoplastic elastomeric block copolymer, the partially hydrogenated thermoplastic elastomeric block copolymer comprising:
one or more A blocks comprising aromatic repeat units, and
one or more B blocks comprising aliphatic repeat units, and
an olefinic block copolymer, wherein the olefinic block copolymer is a copolymer of a first alpha-olefin and a second alpha-olefin different from the first alpha-olefin;
an alpha-olefin linking polymer, wherein the alpha-olefin linking polymer comprises one or more aliphatic sidechains;
an ethylene-vinyl acetate copolymer; and
a first effective amount of a silane;
wherein a sum of a ratio I, II, III, IV, V, and VI is from about 5.0 to about 16.0;
wherein the ratio I is a ratio of a total parts by weight of the olefinic block copolymer present in the crosslinked and foamed composition to a total parts by weight of the partially hydrogenated thermoplastic elastomeric block copolymer present in the crosslinked and foamed composition;
wherein the ratio II is a ratio of a total parts by weight of the alpha-olefin linking polymer present in the crosslinked and foamed composition to a total parts by weight of the partially hydrogenated thermoplastic elastomeric block copolymer present in the crosslinked and foamed composition;
wherein the ratio III is ratio of a total parts by weight of the ethylene-vinyl acetate copolymer present in the crosslinked and foamed composition to a total parts by weight of the partially hydrogenated thermoplastic elastomeric block copolymer present in the crosslinked and foamed composition;
wherein the ratio IV is a ratio of the total parts by weight of the alpha-olefin linking polymer present in the crosslinked and foamed composition to a total parts by weight of the olefinic block copolymer present in the crosslinked and foamed composition;
wherein the ratio V is a ratio of the total parts by weight of the one or more ethylene-vinyl acetate copolymer present in the crosslinked and foamed composition to a total parts by weight of the olefinic block copolymer present in the crosslinked and foamed composition; and
wherein the ratio VI is a ratio of the total parts by weight of the ethylene-vinyl acetate copolymer to a total parts by weight of the alpha-olefin linking polymer in the crosslinked and foamed composition.
