Alpine skis have undergone three distinct changes in sidecut design. The earliest skis from the 1800s all the way to modern examples in the late 1990s featured a very small amount of sidecut that produced a ski that was almost rectangular in profile as seen from the top. Starting with the Elan SCX in 1995, and very rapidly thereafter, these designs dramatically increased sidecut, a design known as the parabolic ski, or later known as a shaped ski. With the exception of competition mogul skis, shaped skis continue to dominate wherever skis are used on packed snow or in powder with a firm base underneath. Following the introduction in 2003 of the Volant Spatula, designed by Shane McConkey, "rocker" skis became popular in the North American market. European skiers generally remained committed to full-cambered skis designed primarily for carved turns.
