Zusammenfassung:	9 OF THE DISCLOSURE PLASTIC COMPOSITION, MIDSOLE MADE FROM THE SAME AND METHOD OF MAKING FIELD A plastic composition includes a polymer component. The polymer component includes an ethylene-vinyl (EVA) copolymer, a first ethylene-a-olefin copolymer having a hardness ranging from 55 Shore A to 6 0 Shore A measured according to ASTM D2240, a second ethylene-a-olefin copolymer having a hardness ranging from 8 5 Shore A to 90 Shore A measured according to ASTM D2240, and polypropylene (PP) . The plastic product made from the composition has a loss factor ratio of tan5(-20°C) to tan5(40°C) at a frequency of 10 Hz, which ranges from 2.5 to 3.8. A midsole and a method of producing the midsole are also disclosed.
