Replying to A question for boot fitters/park skiers

Greetings Newschoolers,

I just thought it would be fun to get a good discussion about feet going before the season goes into full swing for most of us. This upcoming winter will be my third season working for a ski shop up at Alta, Utah. As I'm sure most of you know Alta does not have a terrain park and people skiing there have different needs/opinions when it comes to boot fitting (or do they?)

I think the one big difference in the needs of an all mountain skier versus a park skier generally speaking is flex. For me, I prefer a softer boot when I'm skiing park and jibbing around. However, when I take that same boot up to Alta and ski powder or charge through some chopped up snow I find that a stiffer boot with some more support would actually be really beneficial. This leads me into my actual question.

Why do you see so many more park skiers with three piece boots (Full Tilts) than all mountain skiers and vice-versa? Full Tilt makes stiff boots and has replaceable tongues so you can switch from a softer to a stiffer flex. And companies that make two piece boots have softer options that have similar flex to what most park skiers riding Full Tilts are using.

With that being said, I want to know if there are any reasons why a three piece boot would be better for a park skier rather than an all mountain skier. Or is Full Tilt just better/more focused on marketing towards park skiers? Possibly a combination of both?
