Abstract A roller skate having front and rear wheels mounted on a base plate member, a ratchet and pawl assembly mounted in association with at least one wheel such that said wheel is rotatable in one direction only when the pawl engages the ratchet. A back stop member is mounted on the rear of the base plate such that it will engage the ground or other supporting surface when the front of the skate is raised to a predetermined height. The base plate of the roller skate is adjustable along its longitudinal axis. The upper portion of the skate has quick release straps for securing the shoe or bare foot of the skater to the skate.
