Abstract: A ski or snowboard defines a compound curve undersurface having a concave camber portion and a reverse camber convex portion. The ski or snowboard includes an upwardly curved tail portion and an upwardly curved front shovel portion. The transition between the concave camber portion and the reverse camber frontal portion defines a front contact point while the transition between the concave camber portion and the upwardly curved tail portion forms a rear contact point. A ski boot is secured to the upper surface of the ski in accordance with conventional fabrication techniques and is positioned overlying the concave camber portion.

Abstract: A pair of rearwardly controlled snow skis including a relatively rigid weight-bearing rear portion for mounting of ski boots thereon and projecting rearwardly from the boot heel to form a trailing portion terminating in a trailing edge. The skis project forwardly of the boot and have the top and bottom surfaces tapering inwardly toward one another to form a relatively flexible planing portion. The skis also taper outwardly along their opposite edges to form a relatively wide upturned shovel at the front extremity thereof.
