A flexible shoe includes an under sole, a foot bed, a first over-foot portion, and a second over-foot portion. The under sole is formed of ballistic nylon. The foot bed is arranged on an upper surface of the under sole. The first over-foot portion is attached to the under sole and is configured to flexibly overly an instep of a foot of a user forward of an ankle of the user. The second over-foot portion is configured to flexibly wrap around a heel of the user rearward of the ankle of the user. The under sole, the first over-foot portion, and the second over-foot portion define a cavity configured to enclose the foot of the user. The foot bed is positioned entirely within the cavity.

ARTICLE OF FOOTWEAR WITH KNITTED COMPONENT HAVING PLURALITY OF GRADUATED PROJECTIONS

An article of footwear includes a sole structure and an upper that is attached to the sole structure. The upper defines a cavity that is configured to receive a foot of a wearer. The upper is at least partially defined by a textile. The textile includes a first area that is substantially smooth. The first area defines a reference boundary that conforms to the cavity. The textile includes a second area. The second area includes a plurality of projection structures that project away from the reference boundary and outwardly from the cavity at varying heights. The second area includes a plurality of recess structures that recess away from the reference boundary and inwardly toward the cavity. The plurality of projection structures and the plurality of recess structures are in an alternating arrangement across the textile.

STRUCTURE AND PROCEDURE FOR MAKING A SHOE WITH KNITTED UPPER
20230055536 · 2023-02-23 ·

A procedure for making a shoe including steps of weaving/construction of an upper, forming the upper in which two previously constructed stockings are a tube that is closed on one side while the other end of the tube remains open, subjecting the upper to a steam jet that dampens and softens a thermosetting polymer yarn, and passing the upper through a high-temperature kiln. Construction of the sole entails inserting the upper into a shoe-tree of a mould, positioning the shoe-tree with the upper and closure between two rings of the mould for polyurethane injection. Because of the presence of the arch structure a barrier that limits the passage thereof to the inner part of the upper, with filling of the mould, passage of predetermined quantities of polyurethane only through the slots of the arch structure permitting joint points to be created between the sole and upper and with the inner.

FOOTWEAR WITH MULTIPLE LOCKDOWN CONFIGURATIONS
20230054105 · 2023-02-23 ·

An article of footwear includes a sole, an upper, a first collar fastener, a second collar fastener, and a strap. The upper is connected to the sole and includes a hindfoot portion and a collar extending from the hindfoot portion. The collar is configured for movement between a first position in which a first side of the collar is an exterior side, and a second position in which an opposite second side of the collar is the exterior side. The first collar fastener is mounted to the first side of the collar. The second collar fastener is mounted to the second side of the collar. The strap extends from the upper and includes a strap fastener. In the first position of the collar, the first collar fastener connects to the strap fastener. In the second position of the collar, the second collar fastener connects to the strap fastener.

FOOTWEAR WITH PROTUBERANCES AND CONSTRUCTION THEREOF
20220361628 · 2022-11-17 ·

A footwear including a vamp and an inner sole defining in combination a Volume of Treatment (VOTf) and an outsole coupled to at least one protuberance, that when in use, comprises a Point of Contact (POC) with a surface, and wherein dimensions of the VOTf are defined by a position of said POC in 3D space in relation to the outsole and/or insole and/or any selected point within the VOTf. Also disclosed are a method and a computer program product program code for manufacturing same.

Knit textiles and uppers, and processes for making the same

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.

Multi-layer extruded uppers for articles of footwear and other foot-receiving devices

Upper components for footwear include: (a) a first layer including a first filament including first plural, non-intersecting, spaced apart path segments (wherein the first filament may have a width dimension of less than 3 mm wide); and (b) a second layer including a second filament including second plural, non-intersecting, spaced apart path segments (wherein the second filament may have a width dimension of less than 3 mm), wherein the second layer is fused to the first layer at locations where the layers contact one another. Additional layers of material, including additional layers with filament, may be included in the upper. The filament material in the different layers may be the same or different from one another (e.g., a thermoplastic material, a thermoplastic polyurethane material, a hydrophobic material, a water-repelling material, a non-water absorbing material, etc.). One or more layers each may be formed as a continuous extruded path of filament.

3D printed articles of footwear with particles

The present invention generally relates to methods of printing articles using three-dimensional printing and other printing techniques, and to articles formed from such techniques, including the printing of articles of footwear containing particles. Certain embodiments are generally directed to composites comprising particles (e.g., reinforcing particles), for example, rubber particles. The particles may be used, for example, to increase slip or abrasion resistance. The composites may also contain polyurethanes or other compounds, e.g., to facilitate fabrication, e.g., using three-dimensional printing and other printing techniques. Other embodiments are directed to methods of making or using such articles. For example, in some embodiments, a composite may be prepared by mixing particles (e.g., reinforcing particles) with at least a first fluid and a second fluid within a nozzle, such as a microfluidic printing nozzle, which may be used to direct the resulting product onto a substrate.
