I have to agree with Jim. Getting high performance boots that fit like a glove is a long learning experience, and even armed with lots of knowledge the process can easiliy go wrong. Your experience at Gorusch was a good lesson, and it proves that even the most reputable bootfitter will not necessarily get you the result that you are after. (there are clearly excpetions to this most notably Harald and Diana)
I really do believe that you have to take control and responsiblity for the boots and the fit. And making the learning curve steeper is the fact that much of what holds true in fitting for recreational (thin shelled) boots does not hold true when fitting for plug boots.
Ron, as for warmth, I have never had a problem with my feet getting cold, and I have not had a problem in the RS 96's. Having said that, people that generally have issues with warmth in boots generally see this magnified in plugs. I have a pair of pull on boot muffs that I never use. Diana uses Hottronics in her boots. They are tricky to install in plugs but it can be done effectively and comfortably.
