sidecut is the extent to which a ski or snowboard is narrower at the waist than at the tips. it is the arcing, hourglass-like curve that runs along a ski’s edges from tip to tail. this curve dictates how skis turn: the deeper the curve, the tighter the turn. straighter skis with less sidecut have a larger turning radius and are more stable at high speeds. the sidecut radius is the radial measurement of the curve that matches the inner curvature of the ski, snowboard, or skiboard. for instance, with a radial sidecut, a circle with a particular radius will perfectly fit the curvature of the sidecut. this particular radius is the given specification from the manufacturer. however, it is not necessary that the radius be constant. mathematical functions, such as a parabola or a clothoid, are often used to describe the curvature of a sidecut. also, multiple radii are stitched together in a piecewise fashion as well.
