Embodiments herein disclose a primary sole part (10) having a foot facing surface (11) and a ground facing surface (12). The primary sole part (10) comprises a plurality of through-going holes (14), wherein the plurality of through-going holes extends in a vertical direction from the foot facing surface (11) to the ground facing surface (12). The foot facing surface (11) is configured to receive an injected sole material for attaching the primary sole part to a ground facing surface (12) of an upper (1).

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 footwear injection mould for Direct Injection moulding of footwear parts, where the mould comprises: a first mould cavity defining a first footwear part, a second mould cavity defining a second footwear part, a first side frame defining at least a part of a first side of the first and second mould cavities, a second side frame defining at least a part of a second side of the first and second mould cavities, and a bottom frame defining at least a part of the first and second mould cavities, where the first and/or the second side frame define(s) at least a part of a first injection channel which is in fluid communication with the first mould cavity and the second mould cavity.

A footwear moulding system for direct injection production of footwear, said footwear moulding system comprising a supporting mould (21), a last (30), an in-mould (22), and an injection channel (40),
wherein the supporting mould (21) comprises at least an in-mould support.

The in-mould (22) is elastomeric and the in-mould (22) comprises an in-mould outer surface (76) configured to be supported by said in-mould support.

The in-mould support comprises at least one support side mould (26, 28) and a support bottom mould (24).

Further, the invention relates to a direct injection footwear production method for footwear by use of such a moulding system.

An article of footwear has an upper that is direct attached with the sole. The sole has a film extending up sidewalls of the sole to a film edge that is prior to the sidewall and the upper joining. Method of manufacture of the article of footwear includes steps of positioning a film over a mold cavity and then securing the film to the mold. The film is heated and then drawn into the mold cavity under a vacuum. The film forms a liner of the mold cavity. A foam composition is injected into the lined mold cavity. As the foam composition expands, the foam composition interacts with and mechanically engages with the upper that is positioned at the mold cavity to allow for the mechanical engagement that results in the direct attach of the sole to the upper. The film is then trimmed from the sole sidewalls.

A system of manufacturing equipment including molds for a direct injection production of footwear. The system includes a design facility that provides a design. A mold manufacturing facility manufactures a mold for the design for molding a sole of the footwear. A last manufacturing facility manufactures a last of the design. A footwear manufacturing facility manufactures footwear according to the design. The last corresponds to the footwear design and the mold corresponds to the footwear design. The mold is a basic direct injection mold and at least partly channels injection material to a mold cavity and further accommodates direct injection mold inserts. Mold descriptive data of the mold inserts is communicated to the footwear manufacturing facility to manufacture the mold inserts, or the mold inserts are manufactured at the mold manufacturing facility based on the mold descriptive data and transported to the footwear manufacturing facility.

Footwear articles are disclosed herein. Footwear articles may be formed using a method comprising disposing uncured resin adjacent a mold, disposing a lattice structure in at least a portion of the uncured resin disposed adjacent the mold, closing the mold using a lasted upper, and injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

A shoe with an upper that is at least partially rendered impermeable, including a sole; an insole; an upper assembly, which at least comprises a breathable lining, a breathable upper, and, interposed between at least part thereof, a layer that is waterproof and is fixed hermetically below the insole, the upper assembly being associated with the insole; and a region providing a waterproof seal of the insole to the sole, the sealing region substantially surrounding the breathable or perforated portion that is free for perspiration.

A footwear apparatus includes a primary outsole having a primary cavity, a secondary outsole connected to the primary outsole and having a secondary cavity, a midsole movably disposed over the primary outsole and secondary outsole including a primary protrusion extending at least partially within the primary cavity, and a tertiary outsole disposed about the primary protrusion. The footwear apparatus defines a z-axis through the secondary cavity and substantially normal to a ground surface, a y-axis extending substantially from the secondary cavity to the primary cavity, and an x-axis substantially normal to a plane created by the z-axis and the y-axis. The midsole is configured to rotate substantially about the x-axis, rotate substantially about the y-axis, to resist rotation substantially about the z-axis. The footwear apparatus is adaptive to a ground surface orientation on which the wearer walks and to rotational movements of the wearers body.

An injected footwear with internal complex graphic is a footwear apparatus that also is an easily manufacturable product. The footwear apparatus includes a sole, an upper, at least one complex graphic, and a sock liner. The sole is below the wearer's foot, while the upper covers the rest of the wearer's foot. The complex graphic integrates an aesthetically pleasing element for the footwear apparatus. The sock liner is used as an intermediate between the wearer's foot and the rest of the footwear apparatus. The complex graphic is internalized in between the sock liner and the upper. The upper and the sole are specifically made of the injectable molding material. A proximal portion of the sock liner is attached to the complex graphic, while the injectable molding material is bonded to a surrounding portion of the sock liner.
