Wait, wait, how is a park boot not a fitted boot, and vice versa?
My SPKs have footbeds, shell mods over a bone spur, heel lifts and a couple of minor liner punches to get them fitting like a glove.
They're a "park" boot, and we've spent a good few hours at the shop making them fit me just right. Are they not, hence, a fitted park boot?
Likewise my friend has Nordica Dobermans, I think the flex is around 130, traditional 4-buckle stiff-as-steel boot and he rides park all day in them with no problems.
What I'm trying to get at, is that a so-called park orientated boot like an SPK or FT can be fitted just as well as a more traditional boot. And which ever you're buying, you should be going to a bootfitter anyway.
