Disclosed is an injection molded Phylon (foam ethylene vinyl acetate) midsole having distinguished advantages, such as increased productivity, improved quality, decreased manufacturing cost, reduced fraction defective, reduced weight or the like, in relation to a conventional injection molded Phylon midsole. The injection molded Phylon midsole is manufactured by an upper molding and a lower molding. The midsole ( 10 ) is formed with a vertical through-groove ( 11 ), a horizontal through-groove ( 11 ), or a cross through-groove ( 11 ). When the midsole ( 10 ) is bonded to an outsole ( 2 ), the midsole ( 10 ) of a proper size within an allowable variation or deviating from the allowable variation widens or constrains the through-groove ( 11 ), so that the midsole ( 10 ) is exactly bonded to the outsole ( 2 ) without deforming the midsole.
