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.

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 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.

The utility model discloses a width-adjustable skate with an interchangeable function, including a shell, a toe cap, a width adjustment screw, and a width adjustment moving part. The bottom of the shell is provided with a replaceable sliding assembly. By means of the replaceable sliding assembly, a user can mount a blade-type sliding assembly or a roller-type sliding assembly as required, thus implementing interchange. Moreover, the width of the skate is adjustable, such that the user feels more comfortable when wearing it.
