There is provided a method for producing a shoe upper capable of producing a shoe upper having a double structure with high productivity. A tubular inner side knitted fabric portion (19) to become an inner side portion of the shoe upper and a tubular outer side knitted fabric portion (11) to become an outer side portion of the shoe upper are knitted with the inner side knitted fabric portion (19) and the outer side knitted fabric portion (11) lined on left and right on the needle beds and with foot insertion opening corresponding portions (110, 190) of the knitted fabric portions (11, 19) connected (process α). In this case, at least one of the inner side knitted fabric portion (19) and the outer side knitted fabric portion (11) is knitted using a fusible knitting yarn including a heat fusible yarn. The inner side knitted fabric portion (19) is tucked in an interior of the outer side knitted fabric portion (11) to form a shoe upper having a double structure (process β). The shoe upper having the double structure is fitted to a last and a thermal process is carried out (process γ).
