A skate for use on a plastic skating surface has a rocker-shaped blade with wheels ahead of and to the rear of the central portion of the blade, the rollers having a resilient rim of such diameter that it is compressed under the weight of the skater, assuring that the blade glides on the skating surface when the skate is sliding in the direction of its length but prevents it from side slip. When the skate is tilted, the wheels provide thrust or braking friction as needed.
