Definitions for "Sidecut"
The component of shape of a snowboard in which the middle is narrower than the tip and tail
The concave arches in the sides of the ski, designed to enhance the ski's turning performance. In general, the more sidecut a ski has (up to a point), the easier it will be to turn. Keep in mind, however, that sidecut can have a negative effect on your forward glide and how well your skis track in a straight line. For this reason, pronounced sidecuts are not recommended for in-track striding or for casual touring across flat or moderate terrain.
The difference in millimeters between the ski's waist (or narrowest part) and the tip and tail. A large sidecut allows skis to carve turns more readily.
