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.

There is disclosed a novel system and method for performance monitoring of athletes. In an embodiment, the system comprises a plurality of sensor modules mounted on different locations of an athlete, wherein at least one of the plurality of sensor modules is a master sensor module configured to interconnect with all other sensor modules to collect performance data for transmission to a computer system configured to collect the performance data. In an embodiment, a sensor module is housed in a cavity of a blade holder in at least one skate of a pair of skates worn by a hockey player.

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.

Disclosed herein are embodiments describing a front and rear ice-skate adapter that are configured to join a respective front and rear ice-skate blade post to the sole of an ice-skating boot. In certain instances each ice-skate blade post is a multi-degree of freedom adjustable cup that adjusts the position of an ice-skating blade relative to the ice-skate boot sole. Each ice-skate adapter generally comprises a skate sole end that attaches to an ice-skate boot sole and a skate end that attaches to a respective ice-skate blade post. A cup body is defined between the skate sole end and the skate end. The skate sole end comprises a surface that conforms to the shape of the ice-skating boot sole. For added stiffness and stability, the skate sole end further comprises a plurality of appendages that extend outwardly from the cup body.

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.
