<p>A sportsboard (10) having an ergonomic upper surface (18). The upper surface (18) of the sportsboard (10) includes at least one upwardly angled portion (20; 22) with respect to a center of the sportsboard (10) adapted to contact the extremities (24, 26) of a rider (28), e.g., the feet, boots and/or bindings. Preferably, the angle is between about 1° and 20°, more preferably between about 4° and 14°, and most preferably between 5° and 12°. The angle preferably accounts for an amount of flex in the sportsboard (10) when ridden, and thus may be, e.g., more preferably in a range of between about 4° and 7° in a flexible sportsboard (10). The extremity contacting sections may be laterally arcuate, may be laterally rotated, and/or may be tilted about a lengthwise axis of the sportsboard (10). In another aspect, to reduce stiffness in the sportsboard (10), a plurality of grooves are formed widthwise across the sportsboard (10), particularly across thicker portions of the sportsboard (10), to reduce the compression forces necessary to bend the sportsboard (10) in a lengthwise direction.</p> |
