Method for manufacturing shoe

A method for manufacturing a shoe, the method comprising:

• putting unvulcanized rubber into an outsole frame formed in a first-stage mold;
• applying predetermined heat and pressure to the unvulcanized rubber in the outsole frame;
• preparing a first film by applying a pretreatment film to one surface of a first release film or first paper to a predetermined thickness and positioning the first film such that the pretreatment film borders a top of the first-stage mold and a top of the unvulcanized rubber in the outsole frame;
• performing vulcanization on the unvulcanized rubber in the outsole frame;
• preparing an outsole of which a top is processed with the pretreatment film by removing the first release film or first paper from the first film;
• preparing a second-stage mold having a midsole frame penetrated vertically and positioning the second-stage mold on the first-stage mold such that the midsole frame is on a top of the outsole frame;
• positioning a first reactive adhesive film on top of the second-stage mold;
• tightly applying the first reactive adhesive film to an inner surface of the midsole frame by heating the first reactive adhesive film and creating a vacuum in the midsole frame;
• preparing a third-stage mold having a fixed frame penetrated vertically and positioning an upper part inside the fixed frame;
• positioning a second reactive adhesive film on a bottom of the third-stage mold such that the second reactive adhesive film is positioned on a bottom of the upper part;
• tightly applying the second reactive adhesive film to the bottom of the upper part by heating the second reactive adhesive film and creating a vacuum between the bottoms of the upper part and the third-stage mold and the second reactive adhesive film;
• injecting liquid foam into the midsole frame coated with the first reactive adhesive film;
• putting the third-stage mold on the second-stage mold such that the bottom of the upper part coated with the second reactive adhesive film is positioned on the midsole frame injected with the liquid foam;
• and
• forming a midsole between the outsole and the upper part by performing a foam process on the liquid foam.
