Upper components for footwear include: (a) a first upper component that includes a first layer having a first material as a first filament including first plural, non-intersecting, spaced apart path segments (wherein the first filament has a width dimension of less than 3 mm wide (and in some examples, less than 2 mm wide, less than 1.5 mm wide, less than 1 mm wide, or even less than 0.75 mm wide)); and (b) a second upper component including a fabric element formed at least in part of a fusible material, wherein the fusible material of the second upper component is fused to the first material of the first upper component (e.g., in an adhesive-free manner). Additional layers of material, including additional layers including filament and/or fabric elements, e.g., of the types described above, may be included in the upper.

In one aspect of the disclosure, a knitted component for use in an article of footwear may include a first layer with a multi-bed first area having a first surface and an opposite facing second surface. The knitted component may include a second layer with a second area overlapping the first area. The second area may have a first surface and an opposite facing second surface. The knitted component may include a plurality of interlayer knit stitches interlooping at least one yarn of the first layer with at least one yarn of the second layer at an interface between the second surfaces of the first and second areas. The interior surfaces of the first area and the second area may define at least part of a freely separable area between the first and second areas.

A system and method for manufacturing an upper of the footwear by additively depositing material to form a fabric element having a plurality of threads, and incorporating the fabric element into the footwear. The plurality of threads of the fabric element may form at least one texture. Additionally or alternatively, the fabric element may be manufactured with a shape that conforms to a 3-D contoured surface.

A reel based closure device includes a housing component, a spool that is rotatably positioned within an interior region of the housing component, and a tightening component that is coupled with the housing component. The tightening component is operably coupled with the spool so that an operation of the tightening component causes the spool to rotate within the interior region of the housing component to wind a tension member about the spool. The housing component is configured so that the tension member is routed axially below the housing component's interior region and to one or more guides that are positioned along a lace path of an article, such as a shoe.

An article of footwear may include an upper having a knitted component formed of unitary knit construction. The knitted component includes a collar portion and a throat portion. The collar portion has a cylindrical configuration and the throat portion extends outward from the collar portion. In some configurations, the collar portion and the throat portion form (a) a first area of an exterior surface of the upper and (b) a first area of an interior surface of the upper. The upper may also include a cover component secured to the knitted component and forming (a) a second area of the exterior surface of the upper and (b) a second area of the interior surface of the upper.

A spacer textile material has at least a portion of a tensile strand located between a first layer and a second layer of the spacer textile material where the first layer and second layer have been joined together to form channels in which the tensile strand moves freely. The tensile strand travels through the spacer textile material in a non-linear direction. Further, the channels may be formed in the spacer textile material in non-linear directions. The spacer textile material with a tensile strand may be incorporated into an article of footwear.

An article of apparel includes a first layer and a second layer. An auxetic structure penetrates the first layer. The auxetic structure includes a plurality of interconnected members forming an array of cell units. Each of the plurality of interconnected members form cell walls with interior recesses defined within the cell walls. The second layer is coupled to the first layer via the auxetic structure.

An article of footwear may include a knitted component that at least partially forms an upper. The knitted component may include a first knit layer and a second knit layer, the first knit layer being separable from the second knit layer such that a pocket is located between the first knit layer and the second knit layer. A cable may be located at least partially within the channel. A cable guide may additionally be located at least partially within the channel, where the cable guide includes at least one curved surface for contacting the cable. The cable may extend around the at least one curved surface such that the cable changes directions within the channel.

A procedure for making a shoe with a knitted upper, including a series of steps in whichduring an upper shaping steponce the internal stocking has been placed on the shoe tree, a membrane element (3) is placed in position, which covers the portion corresponding to the sole of the shoe tree and a lateral portion. The membrane element is a single-body element formed of a polymer membrane that has adhesive material on both sides thereof and features a series of suitable shaped and positioned perforations (30). The membrane element is designed to create a support structure for the two stockings so that the shoe obtained has and maintains a structured shape. Once the upper is complete, a sole is constructed by injection moulding in order to create a shoe that is a single, homogeneous, compact, and structured body.

A fiber bound engineered material is provided that imparts an intended characteristic at an intended relative location. A fiber layer is entangled with additional fibers in a manner to create a non-uniform engineered material. The lack of uniformity of a fiber bound engineered material may be accomplished through manipulation of the fibers and/or through fiber binding a scrim. The fiber layer binds with additional fibers through entanglement such that a mechanical connection between the entangled fibers is provided. This entanglement allows the fibers to bind without supplemental adhesives, interlacing, or connections. Variations in the fibers and/or inclusion of scrim materials prior to entanglement allows for an intended characteristic (e.g., a functional characteristic) at an intended relative location (e.g., a position determined by an article to be formed therefrom).
