I am a lower-intermediate skiier. I can ski on blue hills quite decently. However, I feel very insecure due to my inability of carving. Therefore, I really want to learn how to carve. I get the idea of carving is to utilize the skis' edges and rolling both knees. However, when I tried it last night, it did not work at all. I cannot roll both of my knee without losing my balance and falling. What is the trick here ? And how do I learn carving ?
Also, on a side note, is it a bad idea to purchase my first pair of boots online ? How about skis ? I am looking at Rossignol 74 Carbon. Do you guys think this is a good pair for my level ?
