Notice how the ski glides on the top of the ski and then shoots forward and repeats the cycle
How does it work:
The CAT (Classic All Terrain) ski is a hybrid of a snow ski and a roller ski. The CAT ski consists of a bottom ski with grippers on the bottom to keep it from slipping on the ground. Mounted on top of this ski is a mini-roller ski. The mini roller ski can slide back and forth on top of the ski. The CAT ski work by the mini-roller ski gliding over the top of the bottom ski (Note: The bottom ski doesn't slide on the ground). After gliding to the front of the bottom ski on the mini roller ski, the skier will shift their weight to the other ski. This weight shift to the other ski allows the bottom ski to shoot forward with the aid of bungis and the cycle start all over again on the other ski. By using this system you have a perfect ski trail where ever you go. The bungis that are used to shoot the ski forward are also use for resistance. The more the resistance a bungi provides the steeper the hill it simulates. If you are hitting the front of the Catskis that means you are overstriding/gliding. You may either increase the tension of the bungi or instead increase your tempo so you don't hit the front of the ski. We recommend increasing tempo over increasing the tension of the bungi. We feel increasing your tempo is a better solution because it promotes pushing more than gliding.
Roller ski manufactures have been trying to make Classic All Terrain ski for over 100 years with little to no success. They have also been trying to make a classic roller ski that would push and glide like a ski on snow. The CAT ski has solved both of these problems. Other wheeled, classic roller skis teach bad habits, such as pushing off the toe excessively and shuffling. The CAT ski allows the skier to push off the whole foot or the heel and doesn't allow the skier to push off the toe excessively. It accomplishes this by having a short roller ski gliding across a slippery surface. If you push from the heel to whole foot you get a good kick because your body weight is pushing 90 degrees or vertical to the ski. If you push off your toe you have less weight pushing vertically on the ski and thus a higher likelihood of slipping. The majority of classic skiers shuffle. Shuffling means that you are not have a complete weight shift from ski to ski. You can identify this problem easily by seeing if your ski completely leaves the ground at the end of the push phase. If your ski never leaves the gound (the tip of the ski can still touch) you are not having a complete weight shift. If you try to shuffle on the CAT ski the ski will not shoot forward properly or won't shoot forward at all. This is what causes a CAT skier to stumble. You need a complete weight shift to allow the non-weight bearing ski to shoot forward.
You can stride or kick double pole on the CAT ski. It is not possible to double pole . If you try double pole, you will most likely stumble. The CAT ski simulates classic striding and kick double pole technique only.
