Not specifically. He mentioned a woman he was working with, he was punching her boot. I said she sounded like a good candidate for a Vacume boot. He said she also had hip and knee issues and an abducted boot would make things worse for her. He said Fischer is concerned that (inexperienced) fitters might put such skiers in their boots, and the the outcome would not be good.
Bottom line, as it has always been, it that the fitter is as important in the process as the boot, and these boots are not for everyone.
But if they do fit, it doesn't get much better!!!
