An improved roller skate construction in which the front and rear shoe-receiving parts of the skate frame are carried respectively on front and rear wheeled axles through the medium of front and rear socket and pedestal structures. Each pedestal is received in its downwardly-opening socket in such fashion that the upper end of the pedestal supportingly engages the closed upper end of the socket to enable limited rocking between the axle and its associated frame part. Each socket and pedestal structure is supplemented by a rearwardly extending tongue on the front axle and a forwardly extending tongue on the rear axle, these being pivoted on the axes of the respective axles. Each tongue is connected to its associated support by a ball and socket joint whose axis is below the interengaging ends of the pedestal and pedestal socket, further augmenting and controlling the relative rocking between the axles and the frame as the skater accomplishes arcuate patterns, etc.
