There is disclosed an improved roller skate having a shoe structure and a unitary sole plate. The sole plate has a bottom surface and an upper surface adapated to receive the shoe structure and defines a heel portion, a toe portion and an instep portion therebetween. The roller skate further includes a pair of truck assemblies secured to the bottom surface of the sole plate at the toe portion and the heel portion by fastener means including a threaded rod and a correspondingly threaded fastener. The sole platet has an aperture for receiving the threaded rod and a recess extending from the upper surface towards the bottom surface. The recess communicates with the aperture and is dimensioned for receiving and confining the threaded fastener therein beneath the shoe structure and to restrain the fastener against rotation. In accordance with a preferred embodiment, the upper surface of the sole plate heel portion is raised with respect to the toe portion so as to form a heel in the sole plate for the shoe structure.
