A shoe manufacturing system (100) processes a to-be-bonded surface (11a) of an upper (11) before bonding a sole to the upper (11). The shoe manufacturing system (100) includes a holding platform (10), a camera (20a, 20b), an applicator (30), a robot arm (40), and a control device (60). The control device (60) identifies a boundary of the to-be-bonded surface (11 a) of the upper (11) that is to serve as a master model M among a plurality of uppers (11), for defining an area of the to-be-bonded surface (11 a) to be processed, based on three-dimensional shape data of the master model M acquired by the camera (20a). The control device (60) controls the robot arm (40) for each of the uppers (11) (such as products P1 to P3) other than the master model M, to cause the applicator (30) to apply an adhesive to the area of the to-be-bonded surface (11a) enclosed by the identified boundary.

Provided is a method for producing a shoe, the method including; arranging a first shoe member and a second shoe member to form an interface through direct contact therebetween, indirect contact with a bonding aid member interposed therebetween, or a combination of the direct contact and the indirect contact, and arranging a conductive material at a position at which the interface can be heated; and inductively heating the conductive material to add heat to the interface and thereby bond the first shoe member and the second shoe member to each other.

A method of making an article of footwear with a braided upper is disclosed. The method includes overbraiding a last to form a braided upper and cutting a bottom opening in the braided upper to remove the last. The bottom opening is cut so as to leave a bottom peripheral portion on the bottom side of the braided upper. A midsole is attached directly to the bottom peripheral portion using a bonding agent.

A sole structure for an article of footwear includes a unitary cushioning component comprising a plurality of scrap foam pieces configured as a plurality of different polyhedron shapes and a resin binder securing the scrap foam pieces to one another. The sole structure may comprise a midsole including an outer shell defining a central cavity. The cushioning component may be disposed in the central cavity as a core of the midsole. A method of manufacturing an article of footwear cutting the scrap foam body into pieces, mixing the pieces with a resin binder, and compression molding the mixed pieces and resin binder in a mold to form a cushioning component of a sole structure of the article of footwear.

The invention provides a method for assisting a joining of a vamp and a sole by vacuum positioning. Initially, the method is that placing a shoe last in a vamp to be joined, coating a liquid medium to a side of the vamp to be joined with a sole or a side of the sole to be joined with the vamp, and combining the vamp with the sole. Afterward, placing the vamp and the sole in a bag, performing a vacuum operation on the bag to press the vamp and the sole, performing a microwave heating operation on the bag to heat the liquid medium to make the vamp join with the sole, and finally taking out the joined vamp and sole from the bag to obtain a finished product.

A method for assembling shoe components includes the steps of: providing at least two shoe components, a shoe last and a film unit; placing the at least two shoe components on an outer surface of the shoe last; removably covering an assembly of the at least two shoe components and the shoe last with the film unit such that the film unit and the shoe last cooperatively define a confining space therebetween; and pumping air out of the confining space and heating the at least two shoe components to shrink and deform the film unit so as to press the at least two shoe components to adhere tightly to each other.
