Pros: Smooth, even flex, custom fit, light weight
Cons: Different feel takes some getting used to
I have had these boots for 2 seasons now, and I love them. After 20+ years in 4-buckle designs from Lange and Tecnica, these were at once a revelation and a mystery. My first day on them, I felt like I was not "properly" attached to my skis -- the smoother, more linear flex in this boot feels much softer than what I had gotten used to in my Tecnica Alus. I have gotten used to this feeling and can now go as hard as I want without feeling like the boot is going to bail on me. I am 43, 185-ish, and ski entirely bumps and off-piste, if at all possible, and quite aggressive. I do not think they would be a good racing boot, particularly beyond an informal approach / rec league, as the fairly rapid initial "breakdown" of their flex would not hold a line, IMO. Great for all-mountain skiing. I do not have a strict off-season regimen for fitness, and I still feel very nimble in these. They are noticeable lighter than my other boots, and I think it helps in rapid unweighting (?) demanded in uneven bumps, crud, varying snow density, etc. I still have a problem with foot pain on top of the instep, which I alleviate through the unbuckle-in-the-liftline ritual, but it goes away towards the end of the day, and I often find myself walking to the car still locked in tight from my last run without realizing it. Boots (and feet!) that feel *better* as the day goes on? What a concept... I wear a size 9 street shoe mostly, though 8 1/2 and 9 1/2 come into play depending on brand. I am fit for a 26.5 shell, with no further modifications to date, and it is quite snug, though as I said it packs out as the day goes on. I only get about 10-12 days per season so I'm not the right one to talk about durability. They should last me 10 years. I paid half price for these, with additional $50 for local fitting as it was an internet purchase. That was still a stretch for my budget, so at full price I wouldn't even touch them, but that's me, and my $$... Overall a great boot, though I don't know that they are so much better than the good 4-buckle designs out there for $100-200 less. It's what's best for you, and I think this was a good move for me.
