I typed a rambling reply to this after my first day out in some HF110s, but in the end most of what I'd say has already been said, and in better terms than I'd say it in. So I'll start with another simple thumbs up rating from a new owner after one day of use on a midwest ski hill and save you the rambling if you want to skip it.
For a little more detail,
I'm another retired 60 year old Salomon SX90 owner/fan re-entering the sport after decades away, who stumbled onto the HF110s and decided to take the plunge. On the rare excursion west over the past years I still skied the black diamonds, but not all day and rather than still being drawn to moguls, I now avoid them. My conditioning lets me down more than my techique does. So while I'm not the hardest of chargers, I do get off the bunny hill.
I wanted the 120s but could not find them locally. I went with custom fit 110s instead, with the assurance from the boot fitter that he could add power straps if I wanted them. (For now, I don't think I need them).
I bought them yesterday, and skied on them today, at a small midwestern ski hill so no black diamonds yet. Overall, unless I was specifically focused on what the boots were doing and how they were working, I didn't notice them. That's meant as a compliment. They didn't stand out as feeling soft/vague. They didn't hurt my feet. Getting in and out of them was trivial. Unbuckling them when I went in for lunch let my ankles sit at a natural angle with my feet in front of me under the table. Yeah that last stuff has nothing to do with actually skiing but it's still true.
Pretty much every thing I noticed about them has already been mentioned. They aren't a GS boot. I'm not a GS skier.
I can fully understand why some people may not like them. _I_ might not even like them if I skied double black diamonds out west every day. But I don't do that. For what I want out of a boot, they work great.
Move over gramps, there's a new kid in town.
BTW - as I was leaving the hill today, I saw a woman struggling with the buckles on her boots. She was probably a few years older than me. My shoes were under the seat she was in and as I walked up she mistook me for her husband and without looking up started asking about how she was supposed to get her feet in these boots... I helped her figure it out and then showed her the Nordicas... When I was leaving, she was helping her husband deal with the buckles on his boots.
They aren't for everyone but they make so much sense for a lot of people.
