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.

A snow ski for use by a skier on a snow covered surface having a tip portion, a rear end portion, and a lower running surface, comprising:
- a first contact area of the lower running surface where the ski contacts the snow covered surface;
- a second contact area of the lower running surface proximate the rear end portion where the ski contacts the snow covered surface;
- a concave camber portion of the lower running surface which extends upwardly from the snow covered surface and is formed between the first and second contact areas;
- a reverse camber convex portion extending forwardly from the first contact area to the tip portion of the ski;
- and
- a boot mounting area extending so as to be formed above the first contact area, wherein the boot mounting area is positioned so that a toe area of a foot of the skier placed in a boot in the boot mounting area is positioned above the first contact area.
