Sole structures including a plate including a first polyolefin resin, and an edge portion comprising a second resin are disclosed herein. The edge portion is more flexible or less rigid than the plate. Articles of footwear formed from the sole structures are also provided. Methods of making the polyolefin resin compositions, plates, edge portions, sole structures, and articles of footwear are also provided. In some aspects, the first polyolefin resin composition includes an effective amount of a polymeric resin modifier.

An upper for a shoe and a shoe including an upper and a sole that is connected to the upper may be provided. In one implementation, an upper for a shoe may be provided, the shoe including the upper and a sole connected to a lower edge of the upper via injection molding. The upper may include a first knitted area having a first stitch density, wherein a portion of the first knitted area may be located at the lower edge of the upper and may include a first meltable material having a first melting temperature. The first meltable material may be melted prior to or during the connection of the sole to the upper and may limit the flow of molding material through a melted area of the upper.

Methods and systems are provided for forming an article of footwear. In one example, forming the article of footwear includes using a perforated last during molding of a midsole of the article of footwear. The midsole may be attached to a seam of the upper of the article footwear to secure the midsole to the upper.

A method and a system for manufacturing a footwear. The footwear includes a footwear upper and a sole. The footwear upper has a lower end. The sole has an upper facing surface, a ground facing surface, and a side surface. The sole side surface includes a lateral side surface and medial side surface. The footwear upper lower end is attached to the side surface of the sole at least partly by a direct injection process of the sole. The direct injection process of the sole is being provided via a mold including at least two side mold parts. method and a system for manufacturing the footwear.

Articles of wear having one or more textiles that include a low processing temperature polymeric composition and a high processing temperature polymeric composition, and methods of manufacturing the same are disclosed. The low processing temperature polymeric composition and the high processing temperature polymeric composition can be selectively incorporated into a textile to provide one or more structural properties and/or other advantageous properties to the article. The textile can be thermoformed to impart such structural and/or other advantageous properties to the article of wear. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Processes and systems for thermoforming articles of wear are disclosed. The process can include utilizing a negative pressure generation system to seal an article in a forming material thereby compressing the forming material onto the outer surface of the article. The process can also include exposing the sealed article to an increased temperature followed by exposure to a decrease temperature, while maintaining the compressive force of the forming material on the outer surface of the article. A positive pressure can also be applied to the sealed article while undergoing the heating and/or cooling steps, which can facilitate the removal of bubbles from the article during thermoforming as well as apply additional compressive force to the outer surface of the article.

A footwear injection mold includes a secondary injection mold defining at least part of an injection chamber. The injection chamber includes a proximal surface defining a part of a distal surface of a footwear part. The secondary injection mold includes a protrusion having an upper contacting surface, a proximal end, a primary surface faced away from the injection chamber, and a secondary surface facing the injection chamber. A normal of the upper contacting surface intersects a center point of the upper contacting surface. A protrusion plane is defined by the normal of the upper contacting surface along a width of the protrusion, and defines a boundary between a primary half and a secondary half of the protrusion, the primary half arranged between the protrusion plane and the primary surface, and the secondary half arranged between the protrusion plane and the secondary surface. A height of the proximal end of the protrusion is larger than the height of the upper contacting surface of the protrusion, relative to the normal of the upper contacting surface.
