A sport board is provided having a running surface which provides improved steering and directional control of the sport board. In one embodiment, the sport board has an arcuate bottom with a series of alternating ridges and grooves. The central ridges and grooves run parallel to the longitudinal axis of the board, while the ridges and grooves in the side areas run perpendicular to the longitudinal axis of the board. In a second embodiment, the sport board comprises a bottom having a small number of a larger ridges and grooves which arrangement provides better control. By use of either approach, however, turning and cornering of the board is more controllable. The board is also fitted with foot straps so as to be easily convertible from a sport board configuration to a snowboard configuration.

1. A convertible sport board having a polymer shell, wherein a running surface is laminated to the bottom of the polymer shell of said board, and wherein said laminated running surface comprises a series of longitudinally extending grooves and/or ridges on the running surface to provide improved gliding and turning properties, and thus allows the sport board to also be used as a snowboard, and wherein the sport board includes a bottom profile configured to a substantially hour glass shape defined as having top edge and a distal bottom edge and a center region positioned between the top edge and the bottom edge, the top edge tapering outwardly along side edges to a first convex bulbous region, the first convex bulbous region then tapering inwardly along a concave center region, the concave center region then tapering outwardly along the side edges to a second convex bulbous region, the second convex bulbous region then tapering inwardly along the side edges to the bottom edge, and wherein the first convex bulbous region is positioned substantially between the top edge and center region, and wherein the second convex bulbous region is positioned substantially between the bottom edge and center region. 2. A convertible sport board as claimed in claim 1 wherein said sport board comprises a foam core, and a harder polymer outer shell, and wherein a running surface is laminated to the bottom of the outer shell, wherein said laminated running surface comprises a series of longitudinally extending, parallel and alternating grooves and/or ridges provided across the running surface, and wherein said sport board has a generally arcuate cross-section profile across the bottom of the board, so as to provide a central portion of said board normally in contact with the snow, and side portions normally not in contact with the snow. 3. A convertible sport board as claimed in claim 2 wherein said grooves and/or ridges on said running surface have a width and spacing such that there are about ten to about eighty grooves per inch of width, and wherein the grooves and/or ridges have depth or height of from about 0.05 mm to about 1 mm. 4. A convertible sport board as claimed in claim 2 wherein the grooves and/or ridges in a central portion of the sport board are aligned with the longitudinal axis of the sport board, and wherein said grooves and ridges on said side portions are primarily not parallel to the longitudinal axis of the sport board. 5. A convertible sport board as claimed in claim 4 wherein the grooves and/or ridges on these side portions have sections wherein at least a portion of the grooves and/or ridges present, are between 10 and 90 degrees off parallel to the longitudinal axis. 6. A convertible sport board as claimed in claim 1 wherein said sport board has a generally planar cross-section profile across the bottom of the board, and wherein said running surface comprises a series of longitudinally extending, parallel and alternating grooves and/or ridges provided across the running surface, at a spacing of between 0.5 and 9 grooves and/or ridges per inch. 7. A convertible sport board as claimed in claim 6 wherein the spacing of said grooves and/or ridges is between 3 and 7 grooves and/or ridges per inch. 8. A convertible sport board as claimed in claim 6 wherein a series of parallel ridges is provided, and wherein the ridges are from 1 mm to 10 mm in height. 9. A convertible sport board as claimed in claim 6 wherein a series of parallel ridges is provided, and wherein the ridges are from 2 mm to 5 mm in height. 10. A convertible sport board as claimed in claim 6, additionally comprising grooves between the ridges, and wherein said grooves have a depth of between 0.1 to 2 mm. 11. A convertible sport board as claimed in claim 1 wherein at least 50% of the entire running surface of the sport board comprises ridges and/or grooves. 12. A convertible sport board as claimed in claim 1 additionally comprising at least one foot strap on the top surface of said sport board. 13. A convertible sport board as claimed in claim 12 wherein said foot straps are located within indented wells located on the top surface of the sport board. 14. A convertible sport board as claimed in claim 12 wherein said foot straps are position on the top surface of the sport board so that they are centered on the central, longitudinal axis of the sport board, and extend along the central, longitudinal axis line.
