Abstract: A skate has a blade curved throughout its length to define a convex running edge. A pair of wall members have lower edges that are connected to the blade throughout its length, such wall members extending upwardly from the blade while diverging from each other. Horizontal flanges extend from upper edges of the wall members for securing to a boot sole to form a triangular structure therewith at least at front and rear portions of the skate and preferably the entire length thereof. The blade and said wall member define rounded end surfaces at the front and rear ends of the skate. Also disclosed is a combination skate and boot in which a molded plastic body forms a unitary structure defining a boot portion and a support portion. The support portion is triangular and projects downwardly from the boot portion while tapering inwardly to the socket in which the blade is mounted.
