OK, so after reading through the thread, I am now confused about the issue of 'thigh burn' as it relates to technique/boot fit.
My understanding was that 'thigh' burn is bad; it's a sign that one's weight is too far in the back seat. My instructor from this weekend even went so far as to email this to me yesterday:
I skied Saturday & Sunday. On Saturday, I was apparently skiing in the position of photo 1. Despite what the caption of photo 1 said, I had very little thigh burn, so I thought I was doing 'well'. I have a pretty low volume foot. My boots fit much better with a pair of Superfeet insoles in them. Even at that, I have to have the ankle buckle cranked down. When it's cranked down, my heel stays much more firmly in the heel cup of the boot. When its not, my heels rise up as I pressure the tongue of the boot. This will also result in some pretty painful cramping in the arches/plantar aspect of my foot. Again, on Saturday, I had little to no thigh burn and no foot pain. It was the most comfortable my boots had ever been- I didn't even unbuckle them at lunch!
At the end of the day on Saturday however, my instructor pulled me aside and was explaining that my weight isn't really over the sweet spot of the boot. We tried a few exercises and he had me focus on skiing with my hips more forward. It *felt* like I was in a position like that in photo 2. While I did notice more control over my ski tips, this was also terrible for my knees. It's the kind of pain that makes me afraid I'm doing serious damage to my patellar tendon, and I think if you look at the photo, you can see that happening in photo 2 as well. So simply moving my weight forward isn't exactly the answer either. Also, this gave me excruciating thigh burn by the end of the day. Which, according to my previous assumption that thigh burn is 'bad', had me feeling like I was 'doing it wrong.'
We did some experiments with my flexing the boot and even though their flex is only 80, I can't really flex them properly. Part of this appears to be construction issue where the plastic shell underneath the ankle buckle just hits the top of the foot part of the shell and just won't let me flex them anymore. I could flex them more when the buckles were loose and only the power strap was snug. So on Sunday, I tried skiing with the upper two buckles loose-ish and just the power strap snug. I was getting a lot of heel rise and the subsequent pain & cramping in the plantar surface of my feet.
So questions...
1.) It seems, from reading this thread, that sometimes thigh burn is a symptom of a problem with boot fit and sometimes it just means your muscles are not in shape for skiing. Is there anyway to know when its your boots that are the problem vs. you are the problem? I always just assume I suck and its me. That's my MO in a lot of things though...
2.) Regarding above, from what I learned this weekend, it seems that the only way to really discern that knowledge is to have skied properly fit boots before. Once you know what works, its easier to figure out what *doesn't* work. But how are you supposed to figure this out if you've never skied in properly fitting boots before?
3.) If you go to a boot fitter, they make a recommendation for a boot in the shop, but after several days of skiing you really just hate it and it doesn't work for you, is there any recourse??? I mean, I assume you can't just simply return the boots and get a refund. But you still need to purchase boots that actually do work for you. Do most boot fitters have any sort of guarantee or policy for dealing with this sort of situation? I have my first ever appointment with a boot fitter at the hill I will be working next weekend. My instructor spoke pretty highly of him, but I'm worried that he tell me my current boots are ALL kinds of wrong for me and I simply need to buy new boots and start from scratch. The problem with this is that my husband will kill me if I spend the money on new boots this season. And with me not really having a base of knowing what proper fit should feel like, I'm worried that even if I do find a way to get hubby on board with making the investment, I could purchase boots that are all wrong for my anyway. I just don't know what I don't know!
4.) Are comfort vs. proper fit generally mutually exclusive??? There was a comment made early that too many woman's boots are too upright- make for comfort and looking good at apres, not skiing well. This just seemed to imply that a properly fit boot will have some degree of discomfort...?
4.) Final question. I have a well-endowed posterior region. (As Snoop Dogg would say, "Damn baby, you've got a bright future behind you!) Is it possible that I'm actually in the position of photo 3, but maybe in snow pants, with the extra junk in the trunk, appearing like I am in the position of photo 1? I haven't seen any profile shots of me on skis on the snow, so I can only go on feel....and I feel like I am in position 3, but getting feedback that I am more like position 1...
