Described are articles of wear including with a material with color changing properties. The material includes at least one elastic portion having an unstretched colored appearance and a stretched colored appearance. The material also includes at least one fixed portion having the stretched colored appearance regardless of a magnitude of an external force applied to the at least one fixed portion.

A shoe includes a concave body defining sidewalls and a sole of the shoe, and including a first layer received within a second layer. The first layer includes a portion of the sole and upwardly-projecting tabs constituting an inner circumferential wall defining an opening disposed entirely above the sole. The second layer includes a plurality of spaced U-shaped elements each of which includes two walls, forming a portion of an outer circumferential wall, and a bottom, forming a sole-shaped part of the second layer, connecting therebetween. The tabs are characterized by an elasticity that enables them to be pushed outwardly thereby expanding the opening to facilitate receipt of a foot therethrough, and are inwardly-biased thereby being configured to bear upon the foot when received within the cavity, thereby facilitating gripping of the received foot by the shoe.

A footwear device (15, 18, 19, 20, 50, 60,70, 80) has a body comprising one or more strips or sheets of material. Footwear device has an outerside (6) and a footwear contact underside (7). The one or more strips or sheets of material may be resiliently deformable material. An adhesive (8) may be disposed on the footwear contact underside (7).

Shoe-shaped, foot-operated massage device, in particular a shoe-shaped, foot-operated masturbator for men, comprising a footbed (1), an upper (2), a shoe opening (3) between the upper (2) and the footbed (1) for accommodating a foot or to be temporarily connected to a foot, a sole (4), and a base (5) between the footbed (1) and the sole (4), an open masturbator position being provided in order for a penis to be accommodated therein.

A heel structure for an article of footwear protrudes rearward from a heel region of an article of footwear in a direction generally aligned with the longitudinal orientation of the footwear article.

An article of footwear with an upper including a ribbon structure is disclosed. The ribbon structure comprises ribbon sections running in at least two different directions. Ribbon sections are connected at nodes. Between nodes portions of ribbon act like links joining the nodes. The links can be arranged in various geometries, including a rectangular grid and a triaxial grid. The ribbon structure may extend the entire length of the article of footwear, and may extend through a forefoot, midfoot and heel.

An article of footwear with an upper including a ribbon structure is disclosed. The ribbon structure comprises ribbon sections running in at least two different directions. Ribbon sections are connected at nodes that may move substantially independently of other nodes. The ribbon structure can provide strength along one of the directions and may simultaneously remain slack in the other direction.

A shoe including a sole and an upper. The upper is coupled to the sole. The upper includes an outer layer and an inner layer. The outer layer has an outer surface and an inner surface. The inner surface of the outer layer is in direct contact with the inner layer. The outer layer is a hot melt thermoplastic material, and the inner layer is a material different from that of the outer layer. At least a portion of the outer layer is adhered to the inner layer, and the inner layer including a portion not covered by the outer layer.

An article of footwear includes an upper defining a foot-receiving cavity with a heel region, and a heel support device extending around the rear of a heel region from a lateral side to a medial side. The heel support device may include a plurality of slats and a base, the plurality of slats providing a progressive gradient of lengths and/or widths, and/or one or more pegs extending from the device for attachment to a footwear upper, and/or an elongated tip that may be disposed in a cavity of an extension of a heel collar of the upper.

In one possible embodiment, the inventive subject matter is directed to a foot covering, comprising: a thin, flexible compartment for receiving a foot. The compartment has a forefoot section, a midfoot section, and a rearfoot section of selected rigidity. The compartment has a top surface for securing the foot and a ground-facing surface having a sole divided into at least two portions comprising (1) a forefoot portion and midfoot portion and/or (2) a midfoot portion and a rearfoot portion. At least one sole portion comprises a midfoot portion disposed between a forefoot portion and/or a rearfoot portion. In the foot covering, each pair of sole portions is divided along a flexural line running generally transverse to the longitudinal axis of the foot. The sole portions and flexural line(s), in combination with the flexible compartment, have a material construction and are arranged so as to facilitate the close conforming of the foot covering to the foot of an intended user through plantar flexion to dorsiflexion.
