Title: Skateboard apparatus

Abstract: A modified skateboard has runners attached to existing trucks. Top and bottom rails of the runners are jointed and slotted to allow changing runner length upon turning. Mounts are slotted to accommodate varying axle base lengths of skateboard trucks and to permit shifting during turns. Right and left turns are achieved by shifting weight from side to side and shortening the runners and sliding the runners relative to the trucks. Runners are braced to keep rails perpendicular to the top of the board.
