Stuart:
I am not at all a fan of SureFeet, and it is because my son had almost the exact same experience with his boots.? Visited SureFeet several times, progressed from simple foot beds to expensive footbeds, never really got a good fit.? He solved the problem by changing to snowboarding.? I think the boot he was in was probably too narrow for his foot, but never heard anyone else say that.? The Harb instructors are all excellent boot fitters, with primary focus on alignment and then getting the boot to fit the foot well (assuming that the boot is appropriate for your feet).? I'm hoping Lynn will chime in here, because they had to do a LOT of work on her boots (in fact, I think they wound up keeping them after the camp to make one final adjustment and then shipped them to her.
If you decide to do the camp, make sure you tell them on your application of the problems you are having and I am pretty sure that they will either prioritize you to do your work the first day or, better yet, see if you can stop by their shop the day before the camp so that they have all of their equipment there.
For future reference, Rule #1 is "know your bootfitter" but Rule #2 is probably spend lots of time in the shop and keep the boots you are about to buy on for at least an hour to really see how they feel.
