Abstract

The present invention relates to a midsole material composition, a method for producing the midsole material and a shoe sole. The midsole material composition comprises an elastomer, a thermoplastic polymer, a suitable crosslinker and a catalyst, such that the midsole material of the present invention can be fabricated by subjecting the midsole material composition to a phase-inversion crosslinking reaction and a foaming process. The aforementioned thermoplastic polymer, which is a recyclable material, is inverted into a continuous phase after the phase-inversion crosslinking reaction, thereby enhancing a recycling property of the midsole material and improving a reusability of the shoe sole.
