PROBLEM TO BE SOLVED: To provide a shoe excellent in moldability, oil resistance, slip resistance, as well as brilliance and wear resistance. SOLUTION: A shoe has an upper section composed of a thermoplastic elastomer composition (A) comprising 100 pts.wt. of (a) a block copolymer having a crystalline ethylene block and an amorphousα-olefin block, 5-60 pts.wt. of (b) a polypropylene resin composition having a melt flow rate (ASTM D-1238, 230°C, 2.16 kg load) of 700-1,500 g/10 min, and 50 to 180 pts.wt. of (c) a non-aromatic softener for rubber, wherein the component (a) is a mixture of a block copolymer (a1) having a cross type molecular structure and a block copolymer (a2) having a linear type molecular structure, and the weight ratio between (a1) and (a2) is 95:5-70:30.
