Often when it comes the time to choose a new pairs of ski, skiers don’t know what they have to looking for. Ski magazine make great review about the new skis every season. Now how to know which skis pairs is the best for you from all this choice.
First of all, you need to choose a ski which fit with your abilities. If you are a novice skier who spend more time in green and easy blue run. You need to research a ski with forgiveness which mean softer and flexible.  To check the flexibility hold one ski by the tip and with the other hand put pressure on the middle where should be the bending. The ski should bend easily. If you are not sure try on other ski from different brand and quality. If you are an advanced skier you will look for a stiffer ski which will be more stable but less chance of forgiveness.

The second thing to take in consideration is the shape of the ski. Your choice depends of the kind of turn you prefer.  If you like to do short and quick turn you will like to have a ski with a smaller radius and shorter length  at the opposite if you prefer longer turn and cruising around you will like a ski with a bigger radius and taller. The radius is refer to the arc you can do by letting the ski on the snow at approximate 45 degree on the snow and let it slide without to skid . For a small radius don’t go under 11m and for the cruiser stay between 17 and 21 meters. You can find the radius of the skis normally at the tail of the ski marked like this r=17.  A ski with a small radius will be wide at the tip small under the foot and wide at the tail. A ski with a higher radius will be straighter. Think between 15 and 18 meters of radius for a all terrain ski.
A third specification to not forget is the length. In general if you stand the ski front of you, the tip should be between your mouth and forehead high. Long for cruising turn and short for quick turn. If you like to ride long terrain of fresh powder go for a wide skis and long but don’t expect too much on groom terrain.
If you want more information ask a ski and snowboard instructor and take few ski lessons to be guided on your choice in link with your ability, preference of turn and more.
