Yes, I've been on it since the beginning of the season. I really didn't know what to expect when I first tried it, but have found that I really like it. I'm skiing the H110. The fore foot flex is not what you might think from flexing them in the shop. Outside the flex zone becomes more subtle, yet it still does seem to keep the balance point over the front of the foot through the entire range of motion. I find it most noticable on harder snow, but still feel the boot's "sweet spot" in all conditions. From a bio-mechanical point of view the Hawx matches my balance and movements needs better than any boot I have ever skied in the last 15 years. Which would be head, lange, koflach, atomic and technica.
The support is excellent for a boot rated at 110, yet it still allows for that forefoot balance point and support through a larger range of motion than a typical boot. It doesn't fold or squish down on the forefoot either as some might suggest. Hard to put your finger on it or describe it really. I know there are detractors out there, but everyone I know who has spent real skiing time in the boot really like them. They have a very natural feel to them. I doubt you will be disapointed by them unless the fit is just not for you.
They can be ground quit a bit, but heating and stretching should be done very carefully, and maybe not at all. If grinding won't get you there then maybe you should look elsewhere. Remember that you can grind both side to get more width, and not just on the side with the pressure point.
