I personally use the FiverFingers and have since 2008. I have also suggested to clients they might consider the product as a tool in changing posture. It's unfortunate that the court ruling had to do with a technical error of language by Vibram - which, sure, could have been intentionally misleading. However, it seems like that kind of market "leading" happens often in other product arenas.
I wanted to pass on one post about the issue (of minimalist shoes) which I like. You can find lots if you surf around but this article is housed on an EXCELLENT site.
