Has anyone worn a pair of Vibram fivefingers?

Here is the pair I’m looking at specifically.

I really like the idea behind these shoes and I like how they look, despite everyone telling me that they are hideous. I’d be using them for their intended purpose. (e.g. Running, biking, cross training and maybe to throw on for a quick trip running errands.)

They’re just so different that I’m questionable about them. Have you ever owned a pair? Tried a pair on? How did they stand up to whatever you used them for? Were they comfortable? Did they feel like sandals or shoes or something else? Anything you could tell me about them would be mighty helpful.

And yes, I could just go try on a pair, which I plan to do, but everyone knows that shoes never feel the same after the first few days of wearing them.
