Foam compositions and uses thereof

A foam comprising:

• a foamed and crosslinked reaction product of a composition comprising:
• a block copolymer comprising
• a first block and a third block, each independently comprising a linear or branched chain aliphatic polymer having a plurality of aromatic groups attached pendantly thereto,
• a second block located between the first block and the third block and comprising an aliphatic polymer having a plurality of aliphatic side chains attached thereto, and
• a plurality of first ethylenically unsaturated groups present on one or more of the first block, second block, and third block;
• wherein the block copolymer comprises about 60 percent to about 90 percent of the second blocks by weight based upon the weight of the block copolymer;
• an olefinic copolymer comprising a plurality of first olefinic segments and a plurality of second olefinic segments having a different chemical structure from the first olefinic segments;
• one or more linking polymers, each linking polymer comprising one or more third olefinic segments;
• and
• about 20 parts by weight to about 45 parts by weight of an ethylene-vinyl acetate (EVA) copolymer based upon a total weight of the foam, wherein the ethylene-vinyl acetate copolymer comprises a first ethylene-vinyl acetate copolymer having a first vinyl acetate content and a second ethylene-vinyl acetate copolymer having a second vinyl acetate content, wherein the first vinyl acetate content is different from the second vinyl acetate content;
• wherein a ratio VI of a total parts by weight of the one or more EVA copolymer to a total parts by weight of the one or more linking polymers is from about 1.00 to about 2.00;
• wherein the foam has a split tear of from about 2.5 kg/cm to 3.5 kg/cm;
• a hardness of from 40 Asker C to 70 Asker C when the foam is compressed;
• and
• a compression set of about 20 percent to about 35 percent.
