Method for manufacturing shoes having resilient members embedded therein

A method of manufacturing a shoe having a spring installed therein, the method comprising:

• a sole molding operation of molding a sole with a shape corresponding to a foot sole of a wearer, having an upper surface on which a groove is recessed, after a foam material is injected into a mold;
• a plate insertion operation of inserting a plate formed of a rigid material into the groove recessed on the upper surface of the sole;
• an elastic member installation operation of placing an elastic member for providing cushioning power to an upper surface of the plate;
• a cover installation operation of covering the spring placed on the plate by the cover;
• an upper compression molding operation of inserting a last into an upper molded to provide an accommodation portion with a shape corresponding to a shape of the foot of the wearer, having a bottom surface for accommodating the spring and a cover and then compressing, with a press, the upper into which the last is inserted to the upper surface of the sole in a state in close contact with the upper surface of the sole, to mold a shoe including the upper and the sole;
• and
• an insole insertion operation of inserting an insole that comes into direct contact with the foot of the wearer into an inner bottom surface of the upper.
