Abstract
A directionally controllable sled for downhill snow skiing has a unitary plastic body which includes a bottom member formed with a pair of downwardly and longitudinally extending elongated runners along opposite sides thereof. The pair of runners are spaced generally flat bottom surfaces and have inwardly facing plane control surfaces extending generally perpendicular to the bottom surfaces and intersecting along facing edges which are effective for directional control of the sled by the user during sled movement. The runners are formed with smoothly curved outwardly facing sides which are substantially less effective than the inwardly facing runner edges for directionally controlling the sled.
