This is a fork from the interminable Fischer Vacuum thread that I can't bring myself to try to read in its entirety.
Many people, maybe even most people, have some degree of duck-footedness. If you pay attention, you'll see this among family, friends, and strangers on the street or on the beach. I don't have any amount of this stance, as far as I can tell. When I walk naturally in sneakers or bare feet on a surface where you can see my footprints, they are absolutely dead straight ahead. (Of course this and everything else I say in this post comes from someone who has no professional training in any of the disciplines involved.)
This leads to the following thought experiment: Picture someone who is naturally duck-footed standing in front of the base lodge in a pair of abducted boots, clicked into his bindings. Let's assume that the amount of abduction built into the boots matches this skier's natural duck-footedness exactly. Therefore when standing on the skis in a natural stance his skis point straight ahead, even though his feet inside the boots don't. Now let's pretend that this person is still standing in exactly the same place, except suddenly by magic he's me, with my naturally straight-ahead feet. Standing there, I'm uncomfortably duck-footed, so I allow my feet - not changing anything else - to rotate inward, assuming their natural straight-ahead alignment. What happens? Exactly. My skis are now in a subtle wedge. How can this not be a problem? Is it because the amount of duck-footed stance built into the boots is so tiny that it's immaterial? If so, why bother to build it in at all? Presumably it's there precisely so that people who ARE duck-footed aren't fighting a subtle herringbone tendency all the time.
In the middle of last season an unexpected event occurred that led me to need to get a new pair of boots fairly quickly. I went to a shop that has a long-standing region-wide reputation for outstanding boot-fitting and general customer service. This shop is one of the few I've been in that has a real selection of high-performance boots for people with small feet. (I take a 24 shell, which is one size smaller than is commonly available in most men's models.) I was pretty sure of the general direction I needed to head, but they confirmed that independently in short order, saying I needed a low-volume boot but one that was not stupid narrow in the forefoot. I did not go in with any serious preconceived notions about which brands or models might work best for me, and I tried to squelch the minor ones I did have. I tried on at least a half-dozen boots in my size, including an Atomic, a Technica, a Nordica, a Dalbello, and possibly more. (Unfortunately there were no Salomon candidates in my size that day. I was coming off a Salomon Falcon that had suddenly developed an irremediable issue ... or at least I had developed an issue with it. But the fit was always good.) Generally these were detuned race boots in about a 110 flex. I eliminated most of them right away for the same reason I always eliminate boots (including hiking boots, xc boots, ice skates, etc), which is that there's way too much space at the extreme upper boundary of my instep, in the "2nd buckle from the top" area, where I always find myself over-cinching to get firm boot-foot contact. (Yes, I have good custom footbeds.)
The two finalists ended up being the Lange RS 110 SC and the Fischer Vacuum 100 Jr. The Lange fit my foot really well out of the box. The Fischer not quite as well, but it was a close second. I was definitely leaning toward the Lange, but ultimately, after a whole lot of walking around the shop in 23s and 24s, decided I was smack between sizes, and that the smaller size just was not going to work on my bigger foot, punching or no punching. So the Fischer it was. I figured that the minor fit differences which made me favor the Langes originally would be compensated for by the molding process, and as it turned out, I think they were. They definitely hold me in as well as or better than any boots I've ever had. Note that at this point I was only vaguely aware of the ginormous Vacuum thread going on here at Epic, and had paid no attention to it. I was dimly aware of the Soma-tec sticker on the boots, and I had read about the concept casually before, but I paid no heed because I was really trusting the fitter and also trying, like a good dobie, to focus on fit and not on "features," a.k.a., bells and whistles.
My first day on the hill with the new boots was truly horrendous in every way. But after three or four visits back to the shop, over the course of the rest of the season, for their patient and expert adjustments, things were much, much better, even if not totally perfect. They had to do some pretty radical cuff alignment work - work that went beyond the maximum range of the star-shaped cams - to get me off my inside edges and onto a flat ski. From the beginning, my big problem with the boots had been that I was not only inside-edge-heavy, but also that I was always fighting against an insistent wedge in a way that I have not felt since I was about twelve. I mentioned this multiple times at my adjustment sessions. The fitter insisted gently that this was a simple function of being too much on the inside edge, which naturally leads to one ski carving into the other, since they are tipped unequally. Makes sense. Their spiel was that once that problem was straightened out, my perceived wedge issue would disappear. Well, it has been much reduced by the alignment work, but it has not disappeared.
I also mentioned a couple of times at the shop that I was wondering if the "Soma" stance could be contributing to my issues. Their answer was similar to what certain other posters here have said, which is that there is nothing all that unique about Fischer's implementation of the abducted stance, that other mfrs. have it too but just don't call it out, and that that (basically) I was over-thinking it.
I was more or less convinced by that argument. Then today I stumbled by accident across the post below from @Noodler, and for better or worse it got me thinking about this all over again, particularly since Noodler and I had had an ostensibly unrelated (but perhaps not so unrelated after all) private conversation last spring about a subtle sequential edge change habit and a bias toward the BTE that I need to work on weaning myself off of.
Should I get a second opinion about whether this Soma thing might be causing a problem for me? Maybe take a few runs on my old boots (which never caused me this issue) to see if I see any immediate pros / cons? Or should I just file this whole train of thought under "ski gear hypochondria" and get myself to the gym.?
Those on this board who know me well will tell you that I'm not your "average" skier. I have been in it and I can tell.
