1. A method for producing a shoe, the shoe having an air pump device arranged in the heel region, the air pump device comprising at least one bellows, into which at least one air intake duct opens and to which at least one air-guiding duct which opens into the interior of the shoe is connected, the method comprising:
providing an upper having an upper material section and a sole section having a lower face, a midsole having an upper face and a lower face, and an outsole having an upper face,
the upper face of the midsole having surface having a first surface profile and at least one recess bordering the surface of the upper face of the midsole for receiving the at least one bellows of the air pump device, and the lower face of the sole section of the upper having a surface having a second surface profile which is complementary to the first surface profile at least in part such that the complementary surface regions of the second surface profile of the sole section and the first surface profile of the midsole completely surround the at least one recess,
wherein a horizontal extension of the upper face of the outsole and a horizontal extension of the sole section of the upper are greater than a horizontal extension of the midsole such that the outsole and the upper protrude beyond the outer edge of the midsole on all sides if the midsole is centrally positioned between the outsole and the upper, and
connecting the upper, the midsole and the outsole by
applying the midsole centrally to the upper face of the outsole and
applying the outsole with the applied midsole to the lower face of the sole section of the upper, wherein the complementary surface regions of the first surface profile of the upper face of the midsole and the second surface profile of the lower face of the sole section are adhered such that the at least one recess for receiving the at least one bellows of the air pump device is completely enclosed, and
then, enclosing the upper, the midsole and the outsole by an injection mold and overmolding the surface regions of the upper face of the outsole not covered by the midsole, the lateral outer surfaces of the midsole and the lower face and adjacent lateral surface regions of the upper with an edge sole region plastic in order to interconnect the outsole, the midsole and the upper by forming an edge sole region.
