An article of footwear is provided having an elevated plate structure incorporated in the sole structure and optionally including a fluid-filled chamber. The elevated plate structure can include an upper plate and a plurality of legs extending downward toward the outsole. End portions of the legs can engage an upper region of the outsole. The elevated plate structure can form a cage region that can optionally include a fluid-filled chamber substantially disposed therein. The elevated plate structure can further include a lower plate disposed at an upper region of the outsole, which can form a lower portion of the cage region. Portions of the legs can be integrated with impact-attenuating members in the heel region in various configurations and can provide features for the impact-attenuating members, such as support, impact-attenuation and adjustable impact-attenuation features.

A method for producing the shock absorbing member includes: inserting in which each of tubes is housed in a corresponding one of first housings such that molding spaces and the tubes communicate with one another; and molding in which a thermoplastic resin material to form a connection member is heated to melt and injected from a gate toward the molding spaces and the tubes so that the tubes and the connection member are integrally formed.

METHOD FOR PRODUCING A SOLE STRUCTURE FOR A SHOE
20240198615 · 2024-06-20 ·

A method of manufacturing a sole structure includes melting a first material in a first plasticization zone of a first injection line and melting a second material in a second plasticization zone of a second injection line. A first blowing agent is injected into the first material within a first mixing zone of the first injection line. The first blowing agent is a supercritical fluid within the first mixing zone. The first material and the second material are co-injected into a mold to form the sole structure. The first material is injected from a first injection chamber and the second material is injected from a second injection chamber. The first blowing agent nucleates within the mold to expand and foam the first material within the mold.

Foam compositions and uses thereof

Components for articles of footwear and athletic equipment including a foam are provided. The foam portion of the components and articles include a composition which includes a thermoplastic copolyester, the composition having a foam structure. A polymer layer is provided on at least on surface of the foam portion. The polymer layer can control or reduce the water uptake of the foam portion. Methods of making the compositions, foams, and components are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding, or injection molding followed by compression molding.

METHOD OF MANUFACTURING A FLUID-FILLED CHAMBER WITH A TENSILE ELEMENT
20180354217 · 2018-12-13 · ·

A method of manufacturing a fluid-filled chamber with a tensile element includes manufacturing a tensile element and incorporating the tensile element into a chamber. A first material layer, a second material layer, and a spacing structure having a plurality of support portions and a plurality of gaps may be stacked. The material layers may be located on either side of the spacing structure or on one side of the spacing structure. A strand may be stitched through the gaps to join the material layers and to form the tensile element. The spacing structure may be removed, and the first material layer may be spaced from the second material layer such that segments of the strand extend between the material layers. The tensile element may then be secured to opposite interior surfaces of an outer barrier, and the outer barrier may be pressurized to place the strand in tension.

HEELED FOOTWEAR AND METHOD OF PRODUCING HEELED FOOTWEAR
20180338581 · 2018-11-29 · ·

The invention relates to heeled footwear such as a shoe or boot comprising a sole assembly and a heel part. The heel part comprises an insert formed in a first material. The insert comprises a core body delimited by an upper surface, a lower bottom surface, and an outer surface connecting the upper and lower surfaces. At least a part of the outer surface is encased in a second material different from the first material. The outer material forms an outer contour layer of the heel part, and the sole assembly comprises an outsole formed in the second material, said second material being softer than the first material. The outsole and the outer contour layer are designed to be formed in one piece providing an outer sole unit being one component.

ARTICLES AND COMPONENTS WITH UV RADIATION CURABLE ELASTOMERIC MATERIALS AND METHODS OF MAKING THE SAME
20180305581 · 2018-10-25 · ·

A method of manufacturing an article that includes providing an element formed of an elastomeric material or composite; placing the surface of the element in contact with a substrate; and affixing the element to the substrate. The element includes an uncured, partially cured, or fully cured UV radiation curable elastomeric material and optionally one or more regions of an adhesive material. The element is affixed to the substrate while the surface of the element is in contact with a surface of the substrate by increasing a temperature of at least a portion of the element, applying pressure to at least a portion of the element, or exposing the uncured or partially cured UV radiation curable material to UV radiation in an amount and for a duration of time that is sufficient to partially cure the uncured material or to fully cure the partially cured material.

Heel cap manufacturing method and manufacturing equipment

A heel cap manufacturing method includes the steps of: a) preparing a multilayer composite material; b) performing the first time of molding by thermal pressing to the multilayer composite material by a thermal pressing device to obtain a thermal pressed semi-product; c) taking out the thermal pressed semi-product from the thermal pressing device and fixing it to a heel cap mold; d) performing the second time of molding by cold pressing to the thermal pressed semi-product together with the heel cap mold in a cooling device to obtain a cooled semi-product; and e) demolding and rewarming the cooled semi-product to obtain a finished heel cap. The present invention uses the processing manner of molding twice by cold and thermal pressing to manufacture the structurally more complex heel cap, effectively lowering difficulty of the manufacturing process and raising production efficiency. A heel cap manufacturing equipment is also provided.
