Vibram & Five Finger Running Shoes

What's your take on the minimalist shoes?  I've had too many (specifically) feet and ankle injuries in my career to count.  On-line reviews say they are (given time and patience) good for preventing injuries.

Has anyone worn them or have "dirt" on the shoes?  What models suited you?

The only one at our group to have worn them (that I know of) is Steve W.

I have a super high arch, have super wide toes, and am a natural sprinter.  This long distance stuff came with some practice.  I'm sick and tired of getting 200 miles at best in a decent pair of shoes, and at that my pinky toes busting out of the sides or the cushion just feel dead flat in the shoes. 

Comments appreciated.
