On top of this, get a boot that provides really good lateral support. No offense to fulltilt or Dalbello Krypton/Il Moro boots, but they will not provide you the support you truly need to work the ski. You dont need to ski on a 150 flex 95 mm width boot, but something that fits very snuggly and gives you proper support will benefit you greatly.
Anyone who wants to argue about the fulltilt/Dalbello boot hate, find me a sl skier who skis on it and was fast in this modern day and age.
I'm a former racer, I say dumb things.
