I note that neither side here seems very good at "moving on," but perhaps for different reasons. The supporters seem unable to to envision that perhaps their own "spot on" fit experiences are not generalizable to the set of all other skiers, so they assume that anyone who disagrees more than once is a hater. On the other hand, SZK and others who are doubters may be determined to get their point acknowledged, even in the face of resistance, by again offering up personal fit experiences - or melting a single pair of boots - as evidence. But I notice either way that we're consistently conflating personal fit experience with judgements about a total technology.
Look, whether you think these boots are the second coming, or yet another example of premature technological ejaculation, your individual personal experience with these boots (and yes, this includes trying to fit a few score people into them for a season) has zero, 0, nada significance toward figuring out whether the technology ulitmately works or not. As in, over thousands of different feet skiing them for tens of thousands of days. We do not have enough data points to generalize sh*t. Nor will sales figures help for a while, since they're driven for a season or two more by marketing buzz and early adopters than the actual incidence of good versus bad outcomes. That idea - that if people buy them, they must be good - is an ad populum fallacy; go check it out in your logic text. Incidentally, so is the converse, if people don't buy them, they must be bad. At this stage, IMO all we can say is vacuum boots work well for some people and not well for others. Given that we have a lot of variety in our foot shapes, this doesn't exactly qualify as earth shattering news. It's useful to have individuals discuss what problems or successes they had if they specify what kind of foot they have, so others of us can see if our feet might correlate.
In a few years, of course, we'll have enough data, from enough feet, enough miles, and enough fitters, to actually assess vacuum technology. Of course "we" won't have the means or will to aggregate the data and analyze it. The manufacturers might, but they won't be telling. So at the end of this period, ironically, the final judgement will be a mature market, buzz moved on, other technologies available, and we can say, "Oh, yeah, the vacuum boot. It was a) boots' version of the V8, or b) boots' version of the Wankel."
Meanwhile, agree with Supergaper - adults should be able to have a heated debate - but as Cirque says, it's gone on and on and... Maybe time to argue about something more meaningful, like why rocker makes you a bad skier and gives you weird breath besides...
