To EZ10miler: This post is both a ridiculous generalization and a vast leap of logic.
Not all people who run in Vibrams are ultra-running fuel belt wearers. I run 25-30 out of my 70 miles/week in my Vibrams, in fact I just did an 11 miler in them this morning at just under 7 minute pace. So no, it's not just slow-shuffling mystics who wear them, it's racers too.
And as for you next leap in logic, how does running ultras make one a "trend follower"? Anyone who runs 50 miles for fun is fairly radical in my book.
