Your problem is not the boots of several mfg's of boots. The problem is hyper mobility of your ankle joint. Your ankle joint!!
No Edge, You do not seem to grasp that a seasoned and trusted boot fitter has assessed your feet and ankles and you seem to be attempting to do everything in your power to avoid taking that advice. I guess in this day and age where consumers always want to purchase their way out of a bad boot match versus putting any effort into solving the root cause, makes perfect sense.
What this means is that for you who has a hyper mobile ankle, to get this resolved you need to re-read posts 29 and 31. There is no boot out of the box that will solve the issues that you are having. Second point is quit dreaming that doing just one thing, like putting in a forward lean wedge will miraculously change your life. Go back to Nick and have him take any of the six boots you have, pick the one that best holds your heel down out of the box, then have him perform the necessary forward lean "tricks" including increasing your forward lean with a shim to get your ankle range of motion matched to the set-up of the boot. In the interim there is no point in going skiing on any boot that has not had the Forward Lean conundrum addressed before the boot ever sees snow.
My new boots are Head Rebel, 120, 27.5 All of my previous boots have been 27.5
The boot is too big!
I believe there are on some on this site that may be able to help you. @Phil anyone to suggest?
Hmmm. None of your six previous boots worked out. So you went with the same size.
Why were you unable to make progress with the recommended fitters? What was the ratio of talking to listening in your conversations with them?
I am going to suggest an outing with a instructor that has boot fitting experience. My feeling is its not only fit, but technique based on body dynamics which may be misleading you in to your views and experiences.

Based you reply, I would suggest you speak with your fitter. If it was fitted to loose have them address it, if they don’t want too than I would say they sold you bill of goods. In that case you are on your own in find a solution.The boot fitter is an exceptional ski coach. He is the head of the racing program at the mountain that I ski at, but it is not at the level of say... Burke or GMVS. Our program is not a school. He has seen me ski and we spoke a lot about method and technique during the fitting.
The bottom line... my boot is sloppy. The feedback that I received earlier was very helpful. But I am not sure about what I should do to remedy the current situation.
Such as: - Stuff filler around the liner
- Get a new liner maybe even foam
- Go back to the old boot
- Buy a new boot (don't have the funds for that)
- Other ideas.
Good luck! I am also what I refer to as a "Cinderella" with boots, having gone through 5 pairs in 6 seasons (more if you count the pair I had when I moved to Utah!) I have super low-volume feet and hypermobile feet and ankles. It's hard to feel secure with such issues, but I will go back to what @KingGrump said earlier about a technique issue (this is definitely part of the equation for me) and what @HardDaysNight says above-get the heel and ankle locked down and a slightly larger toe box can be worked with.I am planning to go back tomorrow if he is in.
