An elongate strap support system for anatomical support, pain reduction, or therapeutic treatment includes a package containing a first elongate strap support and at least one additional elongate strap support. In one example, the first elongate strap support includes a woven fabric support layer including synthetic fibers. The woven fabric is shaped so as to form an elongated strap with rounded portions. The woven fabric is substantially resistant to stretching in one direction under such test conditions as those specified in ASTM D3759. The first elongate strap support additionally includes an adhesive layer on the support layer for adhesive attachment of the woven fabric support layer to an outer skin surface of a body and a removable cover layer on the adhesive layer.

A separated prosthetic foot with a transverse arch belongs to the technical field of manufacturing of artificial limbs. The characteristics of the transverse arch of the human foot are combined into the previous transverse-straight carbon fiber foot design to improve the stiffness of the prosthetic foot and reduce the weight of the prosthetic foot. A forefoot part employs a separated curved plate design, and two simple curved plates with different curvatures are used for simulating a complex curved surface of the transverse arch of the human, such that the manufacturing cost is reduced, and the various parts of the sole are non-uniform in stiffness distribution: the outer side of the foot is a single-layer forefoot plate with a smaller curvature and minor stiffness; and the inner side of the foot is a double-layer stacked forefoot plate, and the lower layer plate has a large radius in curvature and stiffness.

A shoe including an upper comprising an outersole, a toe portion, and a rigid plate; and a heel comprising a threaded shaft upwardly extending therefrom, wherein the rigid plate comprises a threaded barrel comprising a lower open end and an upper closed end opposite therefrom, and wherein the heel is removably attached to the upper based on the threaded shaft threading into the threaded barrel from the lower open end to the upper closed end, and wherein the rigid plate extends over the heel when the heel is removably attached to the upper, and wherein the rigid plate extends past the heel towards the toe portion along the outersole.

A convertible shoe may include a sole and a plurality of interchangeable heel portions, each selectively attachable to the sole. The heel portions may each include a mounting surface configured to interface with a heel receiver of the sole. The heel receiver may include a fixed hook and a movable hook, with the movable hook being operable by an actuator coupled to a bottom surface of the sole. In some examples, an upper is secured to the sole of the shoe by one or more clamping plates. In some examples, the sole of the shoe is configured to be biased into a default bend corresponding to a high-heeled state even when a low heel is attached to the heel receiver.

A material includes a support layer comprising a woven fiber layer less than 30 mils thick. The support layer includes an elongate strap support. The support layer has a ratio of elongation to tensile strength (lb/in-width) that is less than 0.9 in a first direction and greater than 0.9 in a perpendicular second direction. The material additionally includes an adhesive layer on said support layer for adhesive attachment of said support layer to the outer skin surface of a user and a removable cover layer on said adhesive layer. Methods of use of the material and elongate strap support(s) to a human body include providing anatomical support or therapeutic effects.

A thin, low profile, one time use, disposable non-padded and non-metallic material of ornamental shape, thickness, and flexibility with a low tack pressure sensitive adhesive side to adhere to the bottom of the foot, that protects a passenger's clean/healthy feet from contaminated floor surfaces, while keeping other passengers with dirty/unhealthy feet from transferring their own personal foot disorders onto the floor surfaces of security screening lines. The foot liner is used when passengers are required to remove their shoes during the security screening process before boarding their flight. The foot liner needs to be cost effective due to the large volume of passengers (1.7 million worldwide daily) throughout airports and has a built-in removal tab that can be any size, shape, or length, and can either be non-adhesive or have low tack pressure sensitive adhesive qualities (to stick to the heel to ensure no floor contact) for quick removal of the foot liner, so the wearer's fingers are not exposed to germs during the removal process.
