A skate assembly includes a shell structure and a removable tendon guard. The shell structure includes a heel portion, a lateral ankle portion, and a medial ankle portion. The heel portion is formed to cover a human heel. The lateral ankle portion is formed to extend beyond the heel portion. The medial ankle portion is formed to extend beyond the heel portion. The lateral ankle portion and the medial ankle portion are spaced apart to form a notch extending toward the heel portion. The removable tendon guard is removably attached between the lateral ankle portion and medial ankle portion to cover the notch.

A skate (e.g., an ice skate) for a user (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the user and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface. The skate boot may be designed to better fit the user's foot and/or enhance skating performance of the user, such as by being shaped in accordance with anatomy of toes of the user's foot and/or enhancing integrity of the skate boot.

A boot for a roller skate system has a three-point fastening system for fastening the boot to a rail. The three-point fastening system includes three fastening devices, wherein the first fastening device is arranged in a central position in the heel region of the boot, the second fastening device is arranged on an outer side in the ball region of the boot, and the third fastening device is arranged on an inner side in the ball region of the boot. The rail that can be mounted on the boot is also described.

A skating warmup system includes a shoe having a sole and a recess running parallel with the bottom of the sole, the recess having a rail; and a spine composed of a semi-rigid material, the spine having a notch for slidingly engaging with the rail of the recess and securing the spine into the recess.

A skate (e.g., an ice skate) or other footwear for a user. The skate or other footwear comprises a skate boot or other foot-receiving structure for receiving a foot of the user and possibly one or more other components, such as a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). In some cases, at least part of the skate boot or other foot-receiving structure and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate or other footwear to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured.

A functional shoe includes a sole, a functional part to provide a specific function to the functional shoe, a fixing part provided to fix the functional part; and a coupling part provided to be coupled to the fixing part, and directly or indirectly coupled to the sole, at an opposite side to a side coupled to the fixing part. The fixing part includes a fixing body provided to be coupled to the functional part, and a leg member formed to extend from the fixing body in a reference direction which is a direction facing the sole from the fixing body. The coupling part includes an insertion slot provided inside the coupling part to be open in a direction opposite to the reference direction such that the leg member is inserted into the insertion slot.

A boot form for a hockey skate is made of multiple plastic materials having different hardness properties, or different flexural moduli, and is formed via an injection-molding process or another similar process. One or more of the plastic materials may be reinforced with fibers of glass, carbon, aramid, or another stiffening material to strengthen one or more regions of the boot form. For example, pellets of a first plastic material having a flexural modulus of approximately 190 MPa (e.g., a polyamide elastomer block amide) may be injected into a mold to form a softer upper region of the boot form. And pellets of a second plastic having a flexural modulus of approximately 20,000 MPa (e.g., a Nylon 12 with long glass fibers) may be injected into the mold to form a stiffer lower region of the boot form. Additional skate components may then be attached to the boot form.

Hockey-goalkeeper pads wearable on body parts (e.g., legs) of a hockey goalkeeper to protect these body parts against impacts from a projectile (i.e., puck or ball) while playing hockey, in which the hockey-goalkeeper pads may be configured to enhance performance, use, and/or other aspects of goalkeeping by the hockey goalkeeper, such as by being more durable (e.g., reducing crushing of padding material), improving rebounding of the projectile (e.g., increasing a rebound speed of the projectile and/or a coefficient of restitution), and/or facilitating their donning and securing by the hockey goalkeeper (e.g., connecting to skates).
