What Is Sidecut?
The word sidecut is often used to explain the difference between shaped or parabolic skis and straight skis. Sidecut relates to the shape and dimensions of a ski. Parabolic skis have a small waist, and are wider at the tip and tail.
How Does Sidecut Affect Technique?
Simply put, sidecut simplifies skiing. In the past, turning involved a good deal of muscle action. Now, a skier simply needs to put the ski on edge to initiate a turn. As such, on straight skis you use a good deal of quadricep action. In contrast, on parabolic skis, the primary movements begin in the feet and ankle. Overuse of your quads will create skidding movements. Additionally, shaped skis require less steering or rotary movements than straight skis. You will also need to adjust your stance. Due to their higher edge angles, parabolic skis require a wider stance.
Size Matters
The average straight skis measured 200 centimeters. Today, parabolic skis are rarely any longer than 185 centimeters. In fact, a parabolic ski with a more pronounced sidecut exerts pressure over more ski length than a longer ski with minimal sidecut. This means that a 170-centimeter shaped ski is equally as stable as a 200-centimeter straight ski.
