Twin tip skis are designed for tricks in the park and playful skiing in the mountains.
The construction of twin tip skis
These skis are called twin tip skis because both the tips and tails have upwards curves. The curved-up tips and tails prevent resistance and make it easier to do tricks in the parks and on the slopes. Furthermore, it is possible to make backwards landings with twin tip skis, just as you are able to ski backwards. The twin tip design has more or less become the standard design of most backcountry/freeride skis, because it is a great design for the slightly deeper snow.
Twin tip skis often have a soft flex – both on the long side of the ski and torsional – making them resilient and flexible. Generally, this type of ski also has a wide tip, tail and middle/waist, and the construction consists of soft materials for better shock absorption. Twin tip skis usually have a rockered tip and tail combined with a camper or flat middle.
Twin tip skis are Freestyle skis
Twin tip skis are often called Freestyle skis because they are suited for different Freestyle disciplines, just as snowboards. Different Freestyle disciplines have been part of the skiing scene for many years, but in the 1990s some skiers started to do tricks in the parks made for snowboards. The skiers needed a new type of skis for the new Freestyle discipline, and soon several manufacturers started to produce skis with twin tip design.
