A double-edged snowboard (10) is disclosed. The snowboard includes a middle portion with a core, a tail (14) at the rear end of the middle portion, a shovel (12) at the front end of the middle portion, and a base (18) along the bottom of the middle, tail, and shovel portions of the snowboard.

A double-edged snowboard (10) is disclosed. The snowboard includes a middle portion with a core, a tail (14) at the rear end of the middle portion, a shovel (12) at the front end of the middle portion, and a base (18) along the bottom of the middle, tail, and shovel portions of the snowboard. The base includes a central running surface (24), two outer running surfaces (26 and 28), first and second outer edges (34 and 36), and first and second inner edges (30 and 32). The central running surface is lower than the outer running surfaces. The first and second outer edges surround a portion of the perimeter of the first and second outer running surfaces, respectively. The first and second inner edges are disposed between the central running surface and the first and second outer running surfaces, respectively. The outer edges are generally symmetric about the longitudinal axis of the snowboard, whereas the inner edges may be positioned in a number of ways, depending on the desired performance characteristics of the snowboard. Asymmetric arrangements of the inner edges are disclosed that help accommodate for a skewed foot position on the snowboard. The disclosure also includes a method for manufacturing a dual-edged snowboard consistent with the above description.

A base for a runner for gliding over snow, the runner having a core, the base comprising: (a) a central portion coupled to the core, said central portion including a central running surface, generally defining a central surface plane, and a first inner edge located along at least a portion of the perimeter of said central running surface; (b) a first outer portion disposed adjacent said central portion, said first outer portion including a first outer running surface and a first outer edge located along at least a portion of the perimeter of said first outer running surface, wherein said first inner edge of said central portion is lower than said first outer edge, the angle between the center surface plane and a line running between the first outer edge and the first inner edge lying in the range of between 0.5 and 3.0 degrees; (c) a second inner edge and a second outer portion, said second inner edge being located along at least a portion of the perimeter of said central running surface on the opposite side of said central running surface from said first inner edge, said second outer portion being disposed adjacent said second inner edge, said second outer portion including a second outer running surface and a second outer edge located along at least a portion of the perimeter of said second outer running surface, wherein said second inner edge of said central portion is lower than said second outer edge, the angle between the central surface plane and a line running between said second inner edge and said second outer edge lying in the range of between 0.5 and 3.0 degrees; and (d) a shovel portion is disposed at one end of said running surfaces, wherein said inner edges continue at least partially into said shovel portion, said inner edges having an outward curvature toward the ends of the base, said inner edges continuing in generally the same outward curvature as they extend into said shovel portion of the base, said outer edges being disposed along at least a portion of the outer perimeter of said shovel portion of the base, wherein said running surfaces and said edges are symmetric about the longitudinal axis of the base, the first inner edge and first outer edge being the mirror image of the second inner edge and second outer edge; wherein each of said edges has a tangent point at which a line tangent to the curvature of the edge at that point is parallel to the longitudinal axis of the base, and wherein the tangent points for said inner edges are shifted nearer the shovel portion of the base than are the tangent points for said outer edges.
