Sounds like a lot of anti-technology on the forum here. Sure some changes are gimmicks, but for the most part skis, boots, poles are way better than 10 yrs ago. What is happening is that a lot of the equipment is being specialized for racing and not necessarily making it good for the average skier. Not every skier needs to use the top end race boots or skis, they are for the top end racers. Especially with the boots, they have made them much tighter and more form-fitting (like hockey skates a size too small) for the top racers to get maximum performance. The average person (the other 98%) don't really benefit from the precise fit and would much rather have a slightly more forgiving boot. Alpine is the same, don't buy an ultra-stiff world cup boot if you are a beginner.
Some of the great developments are ultra-stiff poles, NIS binding plates (can't wait til Salomon gives in and uses the same standard) lighter skis, more variety of ski design (zero, soft track, wet snow, etc)
Regarding the foot pain, it doesn't really sound like plantar fascitis to me (a non MD but often injured opinion). If it was you would likely have shooting pain in you foot when you first take steps in the morning (the most typical symptom) as the PF will shorter during the night hence why night stockings that stretch the foot are often a treatment. And to the suggestion that it is Salomon's fault but they won't fess up, that is a strange way to think. Every single person has different feet, especially if you are using orthotics. What works for one person might not work for another, has nothing to do with Salomon making a good or bad boot. In general classic boots have a more flexible sole to allow a proper motion for the diagonal stride, skate boots have a much stiffer sole to transfer the lateral power needed. It makes perfect sense that classic boots would cause a problem and not skate or running shoes, especially for someone with foot problems (assuming the orthotics are for a problem and not just for fun)
