My old ten eighty's have finally become unbearable to use. Each turn feels like there are demons in my boot shanking my ankle, i need new ski boots soon. So i have narrowed my desired boots to either the SPK or Krypton. I am a Jackson Hole skier mainly focused on park but obviously skis alot of the back country and the gnarly stuff Jackson's known for. Help me out newschoolers. Whats your opinion? SPK or Kyrpton?
