Hoping to get a gut check here.
My wife has been complaining a lot about heel lift in her Dalbello Krypton Kryzma I.D. ski boots.
I took her into a reputable boot fitter today. He shell fitted her current boots and then measured her ankle flexion. He said that her ankle plane was fairly static. Its not that she can't flex it, but it has limited range.
He then said, I imagine you try to lean forward in your boot, but you feel like your heel is lifting and that you are going to fall forward, so you end up skiing backseat, and everybody yells at you to stay forward and you just can't. That pretty much sums up my wife's skiing to a T.
When I first met her she was skiing in a traditional 4 buckle Salomon boot. She then switched to the dalbello and her skiing ability went downhill (no pun intended). I figured it was her move from Park City to Snowbird and that she needed to get more comfortable on steeper terrain. As I watched her more and more I realized she wasn't keeping her weight forward enough, I also noticed her ankle flexes much less than mine. I figured it was a woman problem.
He said that there is one way to fix it, with a two pronged approach.
Prong 1: Put her in the most upright boot possible. He recommended Lange. He said that because her ankle has limited movement it is necessary to put her in an upright boot so that she isn't already leaning forward before she begins to engage the front of her boot. Currently her boot is maximizing her ankles forward flex before she can even try to engage the boot. Thus, her heel lifts even with the slightest engagement.
Prong 2: Put her in a really stiff boot. He recommended a 120-130 flex Lange. He said that once she is upright its important to make sure she never flexes through the boot all the way, lets give her something really stiff to lean into. He said that her athletic build and strong legs make him believe that the 130 would be a better flex.
He then told us that he won't recommend a specific boot until he spends about 1 hour with her collecting foot / leg data, but that was a great starting point.
Not ready to spend $800+ when I walked into the shop (I figured we'd be buying orthotics and going on our way) I told him I'd go look into scrounging up some cash and I'd be back. I mean that, if he is a good boot fitter, I'm wiling to spend money with him.
However, I'd like a gut check here first. Does his reasoning sound correct to you? I was impressed that he could tell she had problems staying forward after just 3 minutes with her, but I am also hesitant to put my intermediate - advanced skier wife into a 130 flex race boot.
Please chime in, let me know your thoughts. I really appreciate it.
