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 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 method of manufacturing a frame for an ice skate boot, the method including: a) moulding a substantially T-shaped body having a first plate and a second plate extending substantially perpendicularly from the first plate; b) milling the first plate to form a platform intended to be uppermost on the frame, in use, for supporting an ice skate boot, the platform having a first support for supporting a forward portion of an ice skate boot and a second support, separate from the first support, for supporting a rearward portion of an ice skate boot; c) milling the second plate to form an elongate body defining an elongate length of the frame, the elongate body having first and second arms extending from the elongate body, where distal ends of the first and second arms are connected to the first and second supports, respectively; and d) forming a mounting arrangement on the elongate body for mounting a blade runner to the elongate body, wherein step a) includes the step of integrally forming the first and second plates from a composite material.
