A sportsboard having an ergonomic upper surface. The upper surface of the sportsboard includes at least one upwardly angled portion with respect to a center of the sportsboard adapted to contact the extremities of a rider, 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 when ridden, and thus may be, e.g., more preferably in a range of between about 4° and 7° in a flexible sportsboard. The extremity contacting sections may be laterally arcuate, may be laterally rotated, and/or may be tilted about a lengthwise axis of the sportsboard. In another aspect, to reduce stiffness in the sportsboard, a plurality of grooves are formed widthwise across the sportsboard, particularly across thicker portions of the sportsboard, to reduce the compression forces necessary to bend the sportsboard in a lengthwise direction.
