FOOTWEAR ARTICLE CAPABLE OF HANDS-FREE DONNING

A footwear article includes a collar elevator that is conducive to hands-free donning to secure the wearer's foot during wear. A footwear article capable of hands-free donning includes a sole and an upper having a heel region. The upper includes an inner material layer and an outer material layer. The footwear article also includes a collar elevator positioned between the inner material layer and the outer material layer in the heel region. The collar elevator, in an example, comprises a strand-receiving aperture through which a stitch extends attaching the collar elevator to the upper.

METHODS FOR MANUFACTURING FOOTWEAR STIFFENERS
20230081405 · 2023-03-16 ·

A method is provided for making a microcellular shoe stiffener has first and second adhesive layers coextruded on opposite first and second surfaces of a stiffener core. The stiffener core may include a recycled polymeric material. Nitrogen in a supercritical fluid state is introduced into the extruder for the stiffener core to produce a closed cell foam with a gaseous component. The gas reduces the weight and cost of the stiffener without significantly reducing stiffness and resiliency.

Footwear upper including variable stitch density

An article of footwear includes a sole and an upper at least partially formed of a textile element. The textile element includes a yarn matrix having a plurality of interlocked strands oriented in predetermined directions. A structural element may be captured within the matrix at selected locations. In operation, the matrix is stitched onto a temporary substrate. The substrate is removed and the article coupled to a sole structure to form the article of footwear.

Last for an article of footwear

A last for forming an upper of an article of footwear includes an exterior surface, where the exterior surface includes a plurality of three dimensional structural surface components disposed over at least 50% of the exterior surface of the last.

HEEL CAP MANUFACTURING METHOD AND MANUFACTURING EQUIPMENT
20230068828 · 2023-03-02 ·

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.

Footwear with flexible cage and wedge
11622601 · 2023-04-11 · ·

An article of footwear includes an upper, a midsole, and an outsole, where the midsole is located between the outsole and the upper. A wedge is located between the outsole and the midsole and is preferably made of a material that is less compressible than the midsole. A flexible cage is located on the exterior surfaces of the upper and midsole. In embodiments, the flexible cage is designed to limit the outward expansion of the midsole when the midsole is compressed under load, and thus effectively stiffen the midsole. The total compression of the midsole of the article of footwear is based, at least in part, on a desired orientation of the ankle, knee, and hip joints of a user.
