A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

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.

Disclosed is a sports equipment device, including a footwear portion with a sole, a transport portion including a frame and a movement mechanism fixed under this frame, and including a securing mechanism which is able to removably secure the footwear portion to the frame and which includes an upper front block and an upper rear block which are attached to the footwear portion, and a lower front block and a lower rear block which are attached to the frame and are able to be secured to the upper front block and the upper rear block respectively. At least a portion of the sole is created by molding and is molded onto the upper blocks.
