Side slip

A side slip is a controlled descent on steep slopes by keeping the skis in a parallel position across the fall line and rolling the ankles downhill, allowing the skis to flatten out and lose their edge on the snow. This allows the skis to slip down the snow, either straight down the fall line (side slipping) or at an angle (diagonal side slipping). A side slip is better in firm conditions as soft snow tends to pile up and trip the skier over.
