An injection-molding process for injecting a shoe soling including at least two adjacent injection-molding layers onto a shoe upper drawn over a shoe last, uses a mold cavity including a frame, the cavity being covered at the top by the upper also serving as a mold cover, with plastic material being injected into the cavity below the upper. To produce two adjacent injection-molding layers of plastic materials having different properties and reaction times in one operation, i.e. without needing an interim mold opening, before covering the cavity a film is clamped over it by a clamp mounted on the frame. When filling the cavity, the space below the film is first filled with plastic material to produce the first injection-molding layer and then, to produce the adjacent second injection-molding layer, the space above the film is filled with plastic material. Plastic materials are used that inseparably attach to the film.

An article of apparel or sporting equipment, such as garments and footwear incorporates a molded component formed of a UV radiation curable material. In the case of an article of footwear, the UV radiation curable material may be formed into an outsole. The method of manufacturing such articles include placing an ultraviolet radiation curable material in contact with a molding surface; conforming the UV radiation curable material to a shape of the molding surface, forming a molded component; and removing the molded component from the molding surface, such that the component maintains the shape of the molding surface. The molded component may be exposed to ultraviolet radiation in an amount and for a duration that is sufficient to partially cure or fully cure the UV radiation curable material.

A production process of an insole, the steps of: cleaning an insole mold; spraying an oily release agent into a cavity of an upper mold and a cavity of a lower mold of the mold; uniformly fixing cloth in the cavity of the upper mold; injecting shoe material into the cavity of the lower mold of the mold, covering the upper mold of the mold to lock the upper mold and the lower mold after finishing injecting shoe material, and then placing the mold in an oven for baking, opening the upper mold of the mold after finishing baking, and taking out the insole. The production process of an insole is simple in process and high in yield rate, and uses the characteristics that the cloth and the raw material have good adhesion to directly put the cloth into the mold to take shape, thereby eliminating a glue adhesion process.

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.

The invention concerns a method of producing an article of footwear comprising: providing an upper; providing a mold and opening the mold; inserting the upper into the open mold; closing the mold; and injecting a pressurized molten resin, wherein, after the injecting, there is a gap filled with the resin between a side wall of the mold and an outer surface of at least a first portion of the upper, wherein the gap is essentially zero at a contacting point, wherein the gap increases gradually from the contacting point in at least a first region of the mold.

An item of footwear for magnetotherapy comprises a lower sole in which there is defined a tread surface, an intermediate container which can be received in an opening which is defined in the lower sole, a magnetic field generator, a control unit, a battery, an inner sole which is or can be placed over the intermediate container and a vamp structure which is connected to the lower sole. The intermediate container is produced from material having greater rigidity with respect to the lower sole and comprises respective recesses which are intended to receive the magnetic field generator, the control unit and the battery, respectively.

A rubber composite includes a textile layer and a rubber layer. The textile layer has an upper surface and a lower surface. The textile layer has multiple meshes formed by weaving or knitting at least one yarn. The rubber layer covers the upper surface and the lower surface of the textile layer, and a portion of the rubber layer extends into the multiple meshes to be located between the upper surface and the lower surface of the textile layer.
