ABSTRACT:
A composition that has an ethylene/α-olefin copolymer (A), a blowing agent (B), and optionally, an organic peroxide and a crosslinking assistant. The ethylene/α-olefin copolymer (A) has an ethylene/α-olefin copolymer (A1) having a density of not less than 0.880 g/cm3and less than 0.900 g/cm3and MFR (190° C.) of 0.1 to 50 g/10 min and an ethylene/α-olefin copolymer (A2) having a density of 0.900 to 0.930 g/cm3, MFR (190° C.) of 0.1 to 50 g/10 min and a main melting point peak at a position of not higher than 110° C., in a specific ratio. A foamed product, obtained by heat treatment of the composition, may be further subjected to secondary compression. A laminate made of the foamed product and a layer made of a polyolefin, a polyurethane, a rubber, a leather or an artificial leather. Footwear or a footwear part made of the foamed product or the laminate.
