Sports boot element comprising all or part of a wall designed to form at least part of a lateral and/or frontal and/or rear and/or lower wall of a sports boot, characterised in that all or part of its wall comprises a material (10) comprising a polymer (11) and a hollow microball (12) filler.

A sneaker may comprise an outsole. The outsole may comprise a heel zone disposed adjacent a first end of the outsole. The outsole may comprise a forefoot zone disposed adjacent a second end of the outsole opposite the first end. The forefoot zone may be formed from a first climbing rubber. The outsole may comprise a durability zone disposed at a midfoot of the outsole interposed between the heel zone and forefoot zone. The sneaker may comprise an upper coupled to the outsole. The sneaker may comprise a heel grip having a cup shape configured to be disposed at the first end of the outsole over at least a portion of the heel zone of the outsole and at least a portion of a heel portion of the upper. The sneaker may comprise a toe grip disposed adjacent the vamp of the upper.

An integrated plastic shell skate is provided, including ice skates and roller skates, which includes a shoe inner sleeve, a plastic shoe shell and a shoe rack assembly, the shoe rack assembly is fixedly installed at the bottom of the plastic shoe shell, the shoe inner sleeve is formed by pressing once in the inner sleeve cold pressing die after pre-heating, and the plastic shoe shell is formed on the outer side of the shoe inner sleeve through the shoe shell mold, so that the plastic shoe shell and the shoe inner sleeve are integrated formed as a whole. The present disclosure has the characteristics of portability, comfort, safety, environmental protection, firmness and durability.

To provide a sports inner boot that ensures removal from a sports outer boot to allow an inside to be easily washed and where a drying time be a comparatively short time. A sports inner boot made of a thermoplastic plastic includes a bottom plate disposed in the sports outer boot and a foot wrap portion formed at the bottom plate. The bottom plate and the foot wrap portion are integrally formed. The bottom plate and the foot wrap portion contain an ethylene vinyl acetate copolymer material (EVA).

A method allowing the synchronizing collection of motion and ground reaction forces data at the start of a sporting event which are received from motion and force sensors embedded in insoles worn in the user's footwear. Furthermore, this method allows synchronization of said data with video or television transmission, and if used during, for example, during ski racing, provides information of skis' pitch, roll and heading in a 3-D space, as well as linear and angular velocity, g-forces, and the location and distribution of pressure points and ground reaction forces transferred to the user's feet in a numerical or a graphical form.

A motorized shoe assembly includes an electronic device, such as a smart phone or the like, that is carried by a user. A shoe is provided and the shoe is worn on the user's foot, and the shoe has a sole and a heel. A first roller is rotatably coupled to the sole of the shoe for rolling on the support surface. A second roller is rotatably coupled to the sole of the shoe and the second roller is aligned with the heel. Moreover, the second roller is spaced upwardly from the support surface when the sole rests on the support surface. Alternatively, both of the first and second rollers engage the support surface when the shoe is tilted rearwardly onto the heel. A motor is positioned within the shoe and the motor is in mechanical communication with the second roller. The motor rotates the second roller when the motor is turned on to urge the user along the support surface.

A figure skating boot has a monocoque structure formed of monocoque material including a sole portion to receive the foot thereon, inner and outer side wall portions, a heel cup portion about the heel, two ankle portions extending over the ankles, and front and rear mounting surfaces below the sole portion for connection to front and rear ends of a mounting frame, for example the mounting frame of a skate blade. A heel member is formed separately from the boot and is supported by the monocoque material to extend downwardly from the heel end of the sole portion so that the rear mounting surface is at the bottom of the heel member. Each ankle portion is joined to the respective side wall portion by a relief junction enabling the ankle portions of the monocoque structure to be flexed relative to the side wall portions of the monocoque structure.
