Abstract: A two-piece apparatus for sliding over a surface. The device includes forward and rear runners connected by a linkage which allows a user to increase deviation of the runners from a horizontal plane at the same time that a deviation from the longitudinal axis of the apparatus occurs. Thus, the user can tilt or edge the runners at the same time that a turn is being implemented. The board provides a narrower waist section than the leading or trailing sections on each of the forward and rear runners. In addition, at maximum articulation of the runners, a substantially smooth arc is formed along the inner edge of the runners so that optimal cornering and shorter radii may be achieved. Preferably, each of the runners includes a set of fins along a rearward edge so that the device may bite into the surface more aggressively.
