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 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 protector for protecting a skate (e.g., an ice skate) and a foot of a user (e.g., a hockey player) against impacts, such as from pucks (e.g., during shots, which can be powerful), to reduce risks of pain or injury from such impacts, in which the protector is fastenable to the skate, is configured to cover at least part of a skate boot of the skate, and may be designed to facilitate its use, including by facilitating the user donning (i.e., putting on) and doffing (i.e., removing) the skate (e.g., while the protector is fastened to the skate boot), and/or to look like the skate boot (e.g., so as to be relatively unnoticeable such that it can seem as if it is not there).
