The convertible shoe with interchangeable sole consists of an upper to hold the foot and an interchangeable outsole. There is an attachment surface on the underside of the upper and an attachment surface on the topside of the outsole, and the two attachment surfaces are paired and configured to securely attach the two components while also being detachable to allow for the interchange of different outsoles having different tread surfaces. The attachment surfaces are a non-flat contoured shape. There are two protruding ridges on one surface, one substantially under the toe and the other under the heel and part of the arch. These mate with a recessed channel on the other surface. There is also attachment material on both surfaces that are mated and provide a secure attachment.

A skate including a tridimensional skate boot shell with a sole insert embedded in or received in the skate boot shell such that at least part of a thickness of the sole portion is defined under the sole insert, and a holder under the skate boot shell configured for retaining a ground-engaging skate element. The holder is connected to the sole insert by at least one fastener extending through the at least part of the thickness of the sole portion. A method of manufacturing a skate boot is also discussed.

A skate with a stowable and/or removable roller, blade, ski, or track assembly. A skate has: a shoe; a guiding part mounted to the shoe; a roller, blade, ski, or track assembly mounted to move along the guiding part between a deployed position and a stowed position adjacent a calf or ankle part of the shoe; and a handle connected to move the roller, blade, ski, or track assembly between the deployed position and the stowed position. Related methods include moving the roller, blade, ski, or track assembly between the positions, and locking or unlocking the assembly in either position, for example using a handle.

Provided is a heeling apparatus. The heeling apparatus includes a sole including a forefoot portion and a heel portion. The heel portion has an opening formed therein. In one embodiment, the sole includes a removable portion. The heeling apparatus further includes a wheel assembly including wheel rotably mounted to an axle and a mounting structure, wherein the wheel extends through the opening in the heel portion.

A skate boot shell including a tridimensional outer sub-shell made of a first material, the outer sub-shell including a first sole portion connected to first heel, ankle and side portions; a tridimensional inner sub-shell received within and connected to the outer sub-shell, an outer surface of the inner sub-shell being complementary to an inner surface of the outer sub-shell, the inner sub-shell being made of a second material different from the first material; and a tridimensional reinforcement sub-shell made of a third material different from the first and second materials and bonded inside at least one of the inner and outer sub-shells.

A goalie skate assembly has i) a plastic blade mounting member adapted to releasably receive a metal skate blade therein, and ii) a monocoque carbon fiber and resin composite skate boot body for receiving a foot of the user therein. The unitary structure of the skate boot body includes i) a sole portion, ii) a heel portion extending upwardly from the sole portion for receiving a heel of the user therein, iii) a pair of side portions extending upwardly from opposing sides of the sole portion, and iv) a lower portion extending downwardly from a bottom side of the sole portion so as to surround at least a portion of the blade mounting member. A toe cap mounted on the skate boot body includes a molded plastic outer shell and a liner formed of a fiber and resin composite material bonded to an inner surface of the outer shell.

A method of manufacturing a skate boot shell, including shaping tridimensional outer and inner sub-shells, and bonding the shaped sub-shells together through lamination. The lamination is performed after the sub-shells are shaped and includes applying heat to the sub-shells and/or pressure on one of the sub-shells toward the other against a mold surface. A skate with three sub-shells is also discussed.

A size-adjustable sport shoe includes a shoe head, a shoe insole, and an adjusting telescopic device including a gear, a shaft gear, first and second gear racks, and handle. The first and second gear racks are located at two lateral sides of an elongated adjustment groove at the shoe head, wherein the upper surface of the second gear rack is lower than the upper surface of the first gear rack. The gear shaft is coupled between the gear and the handle. When the handle is folded perpendicularly to an axis direction of the gear shaft, the gear meshes with the first gear rack to lock up the shoe head at the shoe insole. When the handle is folded to coincide with the axis direction of the gear shaft, the gear meshes with the second gear rack to allow the shoe head to be slid from the shoe insole.

A device configured for use within a dedicated footwear is provided comprising a wheel housing, a removable wheel cover, and a deployable wheel member for multi-dimensional functionality of the footwear. The wheel housing may reside within the heel portion of the sole of the footwear. The removable wheel cover may cover the wheel housing within the heel portion of the dedicated footwear, so that a user may optionally cover the wheel housing when wearing the footwear without the wheel functionality. In addition, the removable wheel cover may optionally be removed from the wheel housing, so that the user may insert the deployable wheel member within the wheel housing, so that the dedicated footwear provides rolling functionality. A user may easily remove the deployable wheel member from the wheel housing to cover the wheel housing with the removable wheel cover and return the footwear to traditional use without the rolling functionality.

The present invention relates to a composite skate having an integral skate blade holder and an anatomically designed insole, as well as to an assembly of a skate comprising the composite skate and an inflatable inner boot.
