An article of footwear has an upper that is direct attached with the sole in a article of footwear mold. 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 poisoned at the mold cavity to allow for the mechanical engagement that results in the direct attach of the sole to the upper.

A method of forming an upper for an article of footwear includes providing a first material layer over a shoe last, providing a second material layer over the first material layer such that the first and second material layers adhere to each other at an interface between the first and second material layers, where one or both of the first material layer and second material layer is provided by spray forming a polymer material onto the last. The material layers are removed from the last and turned inside out such that the first material layer includes an exposed surface that forms an exterior surface of the upper.

Embodiments are directed to manufacturing footwear. A first outer mold shell and a second outer mold shell may be provided. A first inner mold body and a second inner mold body may be manufactured. The first and second inner mold bodies may have respective first and second inner mold surfaces. The second inner mold surface, together with the first inner mold surface, may define an internal mold volume. The first and second inner mold bodies may be removably coupled to the respective first and second outer mold shells to form first and second hybrid side rings. The first hybrid side ring and the second hybrid side ring may be installed in an automated injection molding machine. The installed first hybrid side ring may be moved toward the installed second hybrid side ring to provide the internal mold volume. One or more liquids may be injected into the internal mold volume.

Physical foaming a footwear component with a single-phase solution of a polymeric composition and a supercritical fluid is provided. The method include temperature conditioning a mold and then engaging the mold with a robot that conveys the mold to a press. At the press a gas counter pressure is applied to a cavity of the mold before injecting a single-phase solution of a polymeric composition and a supercritical fluid into the cavity of the mold. The process continues with releasing the gas counter pressure from the cavity of the mold and then removing the footwear component from the cavity of the mold. The parameters of the method are configured for the formation of the footwear component in an automated manner.

A method for producing a shoe, in particular a sports shoe. In order to provide an optimally fitting shoe in a simple manner, the method comprises the following steps according to the invention: a) Measuring at least one individual characteristic of the foot of a person and/or one walking characteristic of the person by means of a measuring device; b) Determining the progression of a material characteristic and/or mechanical characteristic of at least one sole or one sole part of the shoe along at least one direction of extend of the sole or of the sole part in accordance with the values measured according to step a) using a specified algorithm or a specified rule; c) Producing the sole or a sole part of the shoe, wherein the material characteristics and/or mechanical characteristics are varied along the at least one direction of extend of the sole or of the sole part such that the material characteristic and/or mechanical characteristics at least approximately correspond to the progression determined according to step b); d) Connecting the sole produced according to step c) or the sole part to an upper in order to complete the shoe.

A method of manufacturing an article of footwear includes positioning an upper on a last that defines openings connected by one or more channels in the last, injecting a material through the one or more channels in the last, and forming a structure on the upper with the material.

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.

In the present invention, a shoe sole member is composed of a foam that has a non-foamed film having a thickness of 50 μm or more on a lateral surface of the foam constituting at least a part of an outer peripheral surface of the shoe sole, in order to provide the shoe sole member composed of the foam having both stiffness and shock absorbing properties and provide a shoe excellent in shock absorbing properties.

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.
