It's called wax and having a clean base structure. Believe it or not, this is how skis are supposed to feel. I know, crazy right? During this unsettling time of good performance, I'd suggest using your edges- you know, the hard part to the sides of the ski you probably filed off seconds after unwrapping them? Yeah those things. They stop you, like, all the time and I con't confirm it but i feel like now would be okay too. Also most people have these things called poles that they hold in their hand. You can use them to push yourself around if need be. Crazy talk, I know.
Thanks for the chuckles. Have a happy holiday OP. Enjoy the new skis.
