A polymeric composition which can be used for the manufacture of rubber articles, in general, such as soles, shoes, boots, sealing rings, rugs, footwear straps and sandals, by the same thermoplastic injection process in equipment (injectors) used for plastics without the need for vulcanization or crosslinking and with different embodiments, according to the final product of interest. The basic components of the present polymeric composition are ethylene vinyl acetate, which may be a combination of ethylene vinyl acetate having a VA content of 19% and ethylene vinyl acetate having a VA content of 28%, and a copolymer of alpha olefin ethylene.

A method for manufacturing a shoe part includes: the first mixing step, the standing step, the second mixing step, the setting step, and the hot press forming step. The invention mainly uses the waste coffee grounds material as raw material to manufacture the shoe part. In addition to the aroma of coffee, the shoes have the functions of deodorization and dehumidification while being worn by the user, thereby achieving multiple objectives of environmentally friendly materials, low cost, strong structure and environmentally friendly after-use treatment.

A piezoresistive sensor featuring a fabric of woven or nonwoven fibers coated with carbon nanotubes can be integrated with footwear or clothing to serve as a pressure sensor that can monitor and/or analyze human activity during the course of the activities of daily living of the wearer.

An interchangeable ornamentation system for a footwear comprises a base fastener affixed to a base. The base and the base fastener collectively define a foundation. A first strap and a second strap are coupled to the base. The first strap and the second strap are both configured to individually couple to foot straps of the footwear for matingly and removable attachment to the base fastener so that the foundation is removably attached to the footwear. A removable ornamentation includes a decorative member and an ornamentation fastener. The decorative member oppositely faces the ornamentation fastener. The ornamentation fastener is configured to matingly and removably attach to the base fastener.

Footwear 1 having a strap 30 comprising a front strap portion 31 interposed between a big toe and an index toe, and a side strap portion 32 put on a top of foot, and a footbed 20 which the strap 30 is attached to and a foot is mounted on. The footbed 20 has a removal portion 20c obtained by removing a site being closer to the outside as seen from a front strap portion 31 while closer to toes as seen from a region which a heel of a user is mounted on. In a state wherein a user wears footwear 1, a removal portion 20c is opposed to a middle toe, a ring toe, a little toe and their base parts, an adductor hallucis transverse head part lying closer to a heel than the base parts do, and an arch-of-foot lateral part in flexor digitorum brevis muscles.

Footwear for strengthening and relaxing foot and calf muscles and for developing overall body coordination includes: a device for fastening the footwear to the user's foot, and a flat sole, the underside of which is in contact with the ground, and the upper side of which is provided with a training element for interacting with the user's foot, the training element being exchangeable, and fastenable in the upper layer of the sole. In another embodiment, the device for fastening the footwear to the foot includes elastic straps secured to the edges of the sole, and a flat sole, the underside of which contacts the ground, and the upper side of which is provided with a training element for interacting with the user's foot, the training element being an insole having through-slots through which the straps can be passed.
