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 single layer of woven fabric less than 30 mils thick. The support layer includes a plurality of anatomical supports each having a pair of substantially straight sides and rounded end portions and all of a substantially same size and shape. Each of the plurality of anatomical supports is at least partially disconnected from a remaining portion of the support layer. The support layer has a ratio of elongation to tensile strength (lb/in-width) that is less than 0.9 in at least one 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. The plurality of the anatomical supports in the support layer is attached to an at least partially continuous portion of the removable cover 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.

The sole of a footwear such as slipper having an outsole. The sole is made of a foam material and outsole area of which is partly laid with a fabric material. The fabric is attached to the outsole layer by a plastic which has been heat pressed to the fabric and the foam material. This provides a strong attachment between the fabric-plastic-foam material.

Provided is a shoe with a replaceable screw-on heel.

An article of manufacture suitable for addressing a problem in a human body includes a material in sheet form including first and second adhesive-coated parts releasably retained on a cover layer. Each of the first and second adhesive-coated parts includes a support layer of synthetic microfiber fabric having a greater resistance to stretching in a first test direction than in a second test direction and an adhesive intermittent across the support layer. Each of the first and second adhesive-coated parts is elongated with straight sides and rounded end portions and is configured to be removable from the cover layer and adhered to an outer skin surface of the human body. The support layer allows the passage of moisture vapor, and the adhesive being intermittent across the support layer increases permeability.

A therapeutic article of manufacture suitable for adhesive application to the skin of a user includes an elongate support layer formed of a single layer of woven fabric. The woven fabric has a ratio of elongation in percent to tensile strength (lb/in-width) that is less than 0.9 in only one of two test directions, where elongation, tensile strength, and test directions are determined under test conditions specified in ASTM (American Society for Testing and Materials) D3759. The article of manufacture additionally includes an adhesive intermittent across the support layer and a removable cover layer releasably retained on the adhesive.

A foot arch support device includes a base seat, a movable unit, high and low heel members, and an actuating unit. The base seat includes a first base plate. The movable unit includes a movable plate that is movable relative to the first base plate between high and low curvature positions. When the low heel member is coupled to the base seat, the movable plate is at the low curvature position. When the high heel member is coupled to the base seat, a support part of the high heel member abuts against the movable plate, and the movable plate is pushed by the high heel member to the high curvature position. The actuating unit is operable for permitting removal of a selected one of the high and low heel members from the base seat.
