Abstract
A snow ski apparatus has an occupant-supporting board, a forward runner with a running surface wider in its forward portion than its rear portion and a rear runner with a running surface narrower in its forward portion than in its rear portion. An axle pivotally connected to the board extends through flanges which lie longitudinally along the sides of the runners. Elastic tension means are connected to the runners to bias the runners toward longitudinal alignment with the board. A runner has an undersurface which intersects an inclined surface at an acute angle to form a biting edge to reduce lateral slippage when making a turn. The runners are molded with upstanding side flanges, and portions of such flanges are removed to modify the flex characteristics of the runner body.
