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.
