Sole structures and uppers for articles of footwear are described that includes features to enhance footwear flexibility, dexterity, natural motion feel, and/or tackiness. Such articles of footwear may provide enhanced properties and feel for use in skateboarding and other activities.

A shoe with a sole, upper, and shaft, whose upper and shaft contain a number of modifications to increase flexibility of the shoe but maintain protection for the wearer of the shoe. These modifications fall into the general categories of notch and aperture. The upper also has a number of protrusions into the shaft to increase protection in the protrusion areas. The location, shape, and size of these notches, apertures, and protrusions are important for optimizing the flexibility and protective qualities of the shoe.

A footwear article is provided having an upper and a wear guard arranged across a vamp of the upper. In one embodiment, the wear guard is configured with a grid pattern of raised articulations extends entirely across a width of the vamp. In another embodiment, the footwear article also include a heel guard positioned above a heel region of the upper. In yet another embodiment, a tab may be coupled to the heel guard.

Footwear uppers and articles of footwear including such uppers include: (a) a first lateral lace-engaging component; (b) a first medial lace-engaging component; and (c) a bladder. The bladder includes: (i) a tongue and/or instep chamber having a first surface and a second surface opposite the first surface, (ii) a first heel and/or ankle support chamber, and (iii) a first fluid line placing the first heel and/or ankle support chamber in fluid communication with the tongue and/or instep chamber. A lace engages the first lateral lace-engaging component and the first medial lace-engaging component such that a first portion of the lace extends across the first surface. The lace may apply a force to the tongue and/or instep chamber, and this force may move fluid from the tongue and/or instep chamber to the first heel and/or ankle support chamber to provide additional support for the heel and/or ankle.

A shoe body-forming piece includes an upper portion including an instep portion and a pair of heel portions separately disposed on one side of the instep portion to make the upper portion have a substantially U-shaped configuration outlined by a perimeter edge and an inner edge; and a shoe-sleeve portion having a connection side at least partially connected to the inner edge, wherein the upper portion and the shoe-sleeve portion are knitted from at least one yarn to form a unitary knit construction with a plurality of courses and wales, so that the shoe body-forming piece does not have any sewing portion as the knitting process is completed; when the shoe body-forming piece is processed to form a shoe body, the upper portion corresponds to a fore portion, a lateral portion, and a heel portion of a foot, and the shoe-sleeve portion corresponds to an ankle portion of the foot.

An article of apparel includes a base layer defined by a Poisson's ratio, and a polymer structure coupled to the base layer. The polymer structure is configured to lower the Poisson's ratio of the base layer. The polymer structure includes a plurality of interconnected members forming an array of cell units. The plurality of interconnected members form cell walls with interior recesses defined within the cell walls.

In certain aspects, the inventive subject matter is directed to production of constructs of footwear and components thereof by jet extrusion. The inventive subject matter contemplates novel processes for making such constructs using jets or streams of materials that solidify as fibers, and which form into two- or three-dimensional webs as they are collected. The webs may be in the nature of films, membranes, or mats. In some embodiments, the inventive subject matter generally relates to nonwoven textiles consisting of webs of superfine fibers, i.e., fibers with diameters in nanoscale or micronscale ranges.

A rapid-entry and rebounding fit shoe having one or both of a rapid-entry heel element and a rapid-entry tongue element and both snap back for fit. The rapid-entry shoe directs a user's foot into or otherwise accommodates a user's foot with respect to, a shoe opening, and thereafter secures a rear portion of rapid-entry shoe about a user's heel as well as forefoot.

A shoe upper of a shoe includes first and second shoe upper sections together surrounding a foot, while covering a tiptoe and a heel of the foot, and a protector provided on part of an outer surface of the second shoe upper section and made of a single type of abrasion resistant resin material. The protector includes a tiptoe protector arranged to correspond to a tiptoe portion of the second shoe upper section, and a medial region protector provided on a medial region, of the second shoe upper section, extending from a backend of the tiptoe protector to a portion of the midfoot. The medial region protector has a deformable portion which has a mesh structure and is more deformable than the tiptoe protector, and a plurality of reinforcement ribs which divide the deformable portion into a plurality of regions.

In one aspect, the present disclosure provides an article formed of a knitted component. The article may be an upper for an article of footwear. The knitted component may have a first portion and a second portion, where the first portion of the knitted component at least partially forms a foot-receiving portion of the upper, where the second portion of the knitted component at least partially forms a strap of the upper, where the strap includes a first edge and a second edge secured to the first portion of the knitted component, and where the strap includes a third edge that extends from the first edge to the second edge.
