popular, and is the most resilient of the three. The feet do not actually have to be angled equally outwards to be considered duck stance. The back foot simply has to be angled less than zero degrees. These angles give the rider a dominant front foot angle at all times which makes it easier for a rider to change the board direction mid-run. This change in board direction mid-run is called riding "Switch" or "Fakie". Duck stance is also very popular for park riders because it gives them the versatility to move their board in all directions. It is easier to spin, balance on rails and boxes, and land "switch" when one's feet are both angled outward. The degree of the angle depends on the individual. Flat stance: Also popular with riders who wish to have a consistent stance riding forward or backward, a flat stance is simply one in which both feet are at a zero angle, or perpendicular to the length of the board. This may result in "toe drag" on narrower boards or if the rider has larger feet, in which the rider's toes overhang the edge of the board and may contact the snow during sharp turns on the toe side of the board. The "Flat" Stance is no longer popular and is not recommended by the AASI (American Association of Snowboard Instructors). Riders who use the flat stance will commonly experience pain in their ankles and calves when turning toe-side and heel-side. Skiboarding Skiboarding is a type of freestyle skiing using short, double-tipped skis, most commonly using regular ski boots, non release skiboard bindings, and no ski poles. By using risers which serve as adapters, standard ski or snowboard bindings are sometimes used. Formerly it was also known as snowblading or skiblading. Now the term skiboarding generally refers to the use of a wider version of a short double tipped ski, while snowblades or skiblades are usually the width of an average ski or thinner. Skiboarding is a recreational sport with no governing body or competition. The first mass produced skiboard was the Austrian Kneissl Bigfoot in 1991. American manufacturers such as Line Skis then began to produce skiboards, and the sport grew in popularity. From 1998 to 2000, skiboarding was part of the winter X Games in the slopestyle event. After it was dropped there was no longer a profession circuit for the sport,
