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.degree. and 20.degree., more preferably between about 4.degree. and 14.degree., and most preferably between 5.degree. and 12.degree.. 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.degree. and 7.degree. 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.
