An article of footwear includes an upper and a strobel stitched to the upper at a series of stitches disposed in stitch holes that extend through the strobel. The strobel and the upper define a foot-receiving cavity with an inner surface of the strobel disposed at the foot-receiving cavity. A midsole is secured to the upper and an outer surface of the strobel is disposed at the midsole. The stitch holes are obstructed such that the stitch holes are not exposed to both the midsole and the foot-receiving cavity. Accordingly, when a flowable polymeric material is injected in a mold cavity to form the midsole with the lower portion of the upper and the strobel in the mold cavity, the stitch holes will not provide a path for entry of the flowable polymeric material into the foot-receiving cavity. A method of manufacturing an article of footwear is disclosed.

A method is provided for making footwear utilizing a spray-on material. The method can include spraying a spray-on fabric onto surfaces of a three dimensional last. The last can be produced using additive manufacturing techniques, such as 3D printing, based on data corresponding to dimensions and contours of a consumer's foot, and/or preselected aesthetic footwear designs. The spray-on fabric is sprayed onto the surfaces of the last and allowed to cure to form a flexible, non-woven fabric upper. The upper can be removed from the last and turned inside out. With the upper turned inside out, a sole can be joined to the fabric upper to form the footwear.

A method for manufacturing a waterproof and vapor-permeable shoe (1) (20) (30) (40) (50) comprising the steps of providing an upper (2) and a lining (3) comprising at least one functional layer (7) of vapor-permeable and waterproof material, providing an insole (5) comprising a functional support sheet (9) of vapor-permeable and waterproof material, coupling the peripheral edge of the functional layer (7) of the lining (3) to the peripheral edge of the functional sheet (9) of the insole (5) by way of a sealing waterproof adhesive (8) so as to shape a sock of vapor-permeable and waterproof material, couple the upper (2) to the outer surface of the lining (3) by way of a vapor-permeable adhesive; and couple a sole (4) to the upper (2) and/or to the lining (3) and/or to the insole (5).

A fabric used for a tongue-integrated upper of a shoe comprises a tubular fabric element. The tubular fabric element comprises a first sock part and a second sock part, the first sock part comprises a first foot and a first leg, the second sock part comprises a second foot and a second leg, with the first foot, the first leg, the second leg, and the second foot continuously formed in this order. The central axis of the first leg and the central axis of the second leg do not coincide with each other and are not parallel to each other, and when the first sock part and the second sock part are placed one on top of the other, the first sock part forms a first layer disposed on the foot side of an upper, and the second sock part forms a second layer disposed covering the first layer.
