An adjustable roller skate includes a skate device and a boot body. The boot body includes a base frame having a bottom side coupled to the skate device, an insole platform having a rear heel portion and a front toe portion frontwardly extended therefrom, and a vamp cover attached to the front toe portion of the insole platform. The insole platform is slidably coupled at the base frame to define an adjustable accommodating cavity between a rear end of the base frame and a front end of the insole platform, wherein the insole platform is frontwardly slid to extend the adjustable accommodating cavity at its maximum size and is rearwardly slid to reduce the adjustable accommodating cavity at its minimum size.

A ski boot with removable and interchangeable soles. In one embodiment, the ski boot has a hull with a shaped plate, a sole adapted to be removed from the hull with the sole having a front portion and a back portion that are separated from each other and constrained to the hull via fixing screws. The removable and interchangeable soles allows the ski boot to be configured for specific skiing disciplines and is compatible with ski bindings provided with a plurality of pins integral with the ski that are fitted into corresponding shaped recesses of the hull. The shaped recesses are positioned on the sides of the plate, which is fixedly constrained to the ski boot.

An article of footwear with a ball contacting surface is disclosed. The ball contacting surface includes a raised peak member at the top and gripping members along a medial side. The ball contacting surface enhances the ability of a wearer to kick a ball with a low trajectory and to control the ball.

A skate (e.g., an ice skate) or other footwear for a user, in which a skate boot or other foot-receiving structure for receiving a foot of the user may be configured to enhance power transfer of the user (e.g., for push-off and skating straight), agility of the user (e.g., for turns), and/or other aspects of performance of the user, such as by comprising a sole region that is configured to be disposed under the user's foot and includes different materials strategically distributed (e.g., in a longitudinal direction of the skate boot or other foot-receiving structure) or otherwise implements these enhancements.

A skate having a skate boot with a non-lasted boot shell, the shell having a first non-lasted three-dimensional sub-shell and a second non-lasted three-dimensional sub-shell, the second sub-shell being interior to and adjoining the first sub-shell, the first sub-shell comprising a first material having a first density and the second sub-shell comprising a second material having a second density, the second density being less than the first density, the shell being shaped so as to have a heel portion, an ankle portion, a lateral portion, a medial portion, and a sole portion; and a ground-engaging assembly disposed on an underside of the skate. Additional sub-shells are possible. Methods of manufacturing the skate boot shell, including molding and build-up, are also disclosed.

A system and method for a crystal mount. The system includes a coupler which has a mount and a base. The mount couples to a decorative item, and the base couples to an object. The system allows decorative items, such as a crystal, to be mounted onto a hook. This allows a crystal, for example, to be mounted within skates or other shoes.

A method of method of manufacturing customized inserts for a boot, such as a skate boot, that is at least partially thermoformable includes receiving numerical data corresponding to a tridimensional shape of a wearer’s foot, and manufacturing a medial side insert and a lateral side insert based on the tridimensional shape of the wearer’s foot. The medial side insert and the lateral side insert are shaped to be insertable into the boot with a core that is dimensioned to generally correspond to a foot size of the boot, with a medial internal surface of the medial side insert and a lateral internal surface of the lateral side insert abutting respective outer surfaces of the core.

A skate boot or other piece of footwear is provided with a flexible midfoot section that is not rigidly connected to either a sole and/or base of the boot, in order to adjustably tighten around the bottom, sides, and/or top of the wearer's midfoot to provide arch support and uniform snugness. The midfoot section is in a “hammock” type arrangement while the ball and heel portions of the wearer's foot rests on the footbed over the respective sole portions.
