Abstract

A composition for preparing a foam, a foam, and a shoe employing the foam are provided. The composition for preparing a foam includes 3-30 parts by weight of a first polymer and at least one of a second polymer and a third polymer. The first polymer is cyclic olefin polymer (COP), cyclic olefin copolymer (COC), metallocene based cyclic olefin copolymer (mCOC), fully hydrogenated conjugated diene-vinyl aromatic copolymer, or a combination thereof. The total weight of the second polymer and the third polymer is 70-97 parts by weight. The second polymer is polyolefin, olefin copolymer, or a combination thereof. The third polymer is conjugated diene-vinyl aromatic copolymer, partially hydrogenated conjugated diene-vinyl aromatic copolymer, or a combination thereof. The total weight of the first polymer and at least one of the second polymer and the third polymer is 100 parts by weight.
