It also serves to release you from your last turn sooner. Another important variable that they haven't really played with yet is camber. Hold the skis together bottom to bottom and look at the gap. This is camber. It usually ranges from three-quarters of an inch to a bit over an inch.
More camber means more springiness or liveliness.
But camber isn't the only factor in springy or lively skis. How well will the ski rebound after the camber is compressed is determined by its construction too. Double camber is something most telemarkers do not want. Picture regular single camber as an arc in the ski from tip to tail. Then picture double camber as a second shorter more curved arc super-imposed onto the larger arc starting just in front of the boot and ending just behind it.
