The invention relates to a method for producing a shoe with an air pump device bellows which is arranged in the heel region, wherein an upper (2), a midsole (3), and an outsole (4) are first provided. The lower face (32) of the midsole (3) has a recess (36) for forming a cavity for the bellows and a surface which surrounds the recess on all sides and which comprises a surface profile, and the upper face (41) of the outsole (4) has a surface with a surface profile which complements the surface profile of the lower face of the midsole. The horizontal extension of the upper face (41) of the outsole (4) and of a sole section (22) of the upper (2) is greater than the horizontal extension of the midsole (3) such that the outsole (4) and the upper (2) protrude beyond the centered midsole (3) on all sides. In order to connect the upper (2), the midsole (3), and the outsole (4), the midsole (3) is first adhered onto the sole section (22) in a centered manner, and the upper (2) together with the midsole (3) are pressed onto the outsole (4) which is provided in the base element (6) of an injection mold. In the process, the complementary surfaces are adhered such that the cavity of the recess (36) is completely enclosed. The upper (2), the midsole (3), and the outsole (4) are then enclosed by an injection mold, and the outsole (4) upper face (41) surface regions which are not covered by the midsole (3), the outer surfaces of the midsole (3), and the lower face and adjacent lateral surface regions of the upper (2) are overmolded with an edge sole region plastic.

This document discloses a process for manufacturing recyclable injection molded microcellular foams for use in, footwear components, seating components, protective gear components, and watersport accessories. The process includes the steps of providing a thermoplastic polymer which comprises at least one monomer derived from depolymerized post-consumer plastic, inserting a fluid into a barrel of a molding apparatus. The fluid is introduced under temperature and pressure conditions to produce a super critical fluid. The process further includes mixing the thermoplastic polymer and super critical fluid so as to create a single phase solution, and injecting the single phase solution into a mold of an injection molding machine under gas counter pressure. The process further includes foaming the single phase solution by controlling the head and temperature conditions within the mold.

According to examples, machine-readable instructions in a computer-readable medium may cause a processor to generate code representing a cavity to be formed in an object, generate code representing a first lattice structure to be formed in the object directly above the cavity, and generate code representing a second lattice structure to be formed in the object in an area adjacent to the first lattice structure, in which the first lattice structure may be stiffer than the second lattice structure. In addition, the processor may output the generated codes, in which a three-dimensional (3D) fabrication system may fabricate the object according to the generated codes.

Orthotic sole devices, systems, methods, and computer readable media are for use with footwear. Three-dimensional scans are used to shape the devices to match the user's feet with the footwear. Each of the devices includes a sunken heel portion, a stopper portion, an arch portion, metatarsal pads, a bunion-cut out shape, and a built-in toe crest portion, all to help redistribute the user's weight away from their forefoot. The devices are infused with eucalyptus oils and silver ions. The devices are automatically manufactured via computer numerical control (CNC) software on a computer readable medium. Milling machines and 3D printers can be used in association with the systems, methods, and computer readable media.
