Can’t ski in new skis

Hello I am a relative beginner skier, I got new skis and now I can’t even pizza stop! I mean k can, just slower to make the movement. They’re same length . I was using old twin tips (rossignol sprayer) no problem and got new Volkl 72 , they don’t seem to respond , it’s like I make a movement and there’s a delay? Hard to explain but it’s the first time I’ve fallen since I started doing. What’s going on ?
