20220369757 · 2022-11-24 · ·

A sole structure for an article of footwear comprises a unitary midsole having a first portion and a second portion rearward of the first portion. A bottom surface of the unitary midsole defines a groove extending from a medial side to a lateral side of the unitary midsole, and a top surface of the unitary midsole defines a slit disposed over the groove and extending from the medial side to the lateral side. The unitary midsole forms a living hinge at the groove and the slit, with the living hinge connecting the first portion to the second portion so that the first portion and the second portion are selectively pivotable relative to one another at the living hinge between a first orientation and a second orientation. The groove is wider in the first orientation than in the second orientation, and the slit is wider in the second orientation.

Footwear or other foot-receiving devices include various conforming fit, stability, and/or “locked down” feel features. The uppers (or foot-covering components) for such articles of footwear (or other foot-receiving devices) may include one or more of: (a) an upper shell defining an interior chamber, wherein the upper shell includes a plantar support surface and sidewalls extending from an outer perimeter of the plantar support surface; (b) a bootie component (e.g., formed as a sock or sock-like garment) received in the interior chamber; (c) one or more foot wrapping bands; and/or (d) an interior midsole within the bootie component. The bootie component and/or the foot wrapping band(s) may be secured to the upper shell at a location inside an outer perimeter of the plantar support surface of the upper shell and beyond the bight line between the sidewalls of the upper and the plantar support surface.

Injection-molding method

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.

Article of footwear upper incorporating a textile component with tensile elements

The present embodiments provide an upper. The upper includes a textile component. The textile component of the upper includes a textile element and a tensile element. The tensile element defines a first segment disposed on a first side of the upper. The first segment of the tensile element is configured to attach the securement device to the textile element on the first side of the upper. The tensile element further includes a second segment that is disposed proximate the lower portion of the upper on the second side. The second segment is fixed relative to the lower portion of the upper on the second side. The tensile element further includes an intermediate segment that extends continuously from the first segment, across the heel region, to the second segment.

ARTICLE OF FOOTWEAR INCORPORATING A KNITTED COMPONENT WITH MONOFILAMENT AREAS

In one aspect, an article of footwear may include a knitted component having monofilament strands knitted substantially throughout and a body portion extending continuously from a heel region, along a lateral side of a midfoot region, over a forefoot region, to a medial side of the midfoot region. The body portion may include a plurality of multifilament courses forming an interior surface and an exterior surface. The body portion may include a first monofilament zone in the midfoot region extending diagonally toward the forefoot region, including a plurality of first monofilament areas forming at least a portion of the interior surface of the body portion and substantially having a medial-to-lateral orientation. The body portion may include a second monofilament zone including at a plurality of second monofilament areas forming at least part of the interior surface. The multifilament courses may define a shape of the first monofilament areas and a shape of the second monofilament areas.

Article of footwear with tubular structures
11666120 · 2023-06-06 · ·

An article of footwear has a tubular structure that may conform to various anatomical features of a foot. The tubular structure has a tunnel, and a tensile strand runs through the tunnel. Applying tension along the tensile strand may cause the tubular structure to conform more closely to one or more anatomical features. The geometry, or path, of the tubular structure on the article may be customized.
