I agree with the bootfitter comment, yet i also hate hearing it over and over at the same time. For some of the people here, bootfitting is not an option, as they live in the midwest, where 90% of the ski shops have highschool- college kids that are fitting people for boots.
As to the thread creator i own some Performas myself. They are very comfortable, but are heavy and a little softer than Id like. They're decent boots for the price but id go with some higher end boots.
