It does seem that Edea might be onto something with the ice Fly. I talked about it this summer when I was stateside and saw my old fitter. He's been around a loooong time, is very knowledgeable and highly well respected in the sport. He told me that Gracie gets hers for free, and goes through a pair ~every 6 months. Considering the price tag on those boots, and their longevity (admittedly, she's harder on her skates than the vast majority of us), I'd hope they're stocking her up.
Perhaps some of the other recent switchees could chime in on how they feel about the longevity. I know I'm hard on my boots, and for that reason alone wouldn't want to be dropping that bank. However, if the technology becomes more affordable, I'd be open to giving them a go.
