I have and love them. I use them for everything *except* running (and, of course, biking). Weights (when I'm doing that), elliptical even. I also just wear them around. I had always had a lot of foot pain - sore arches, plantar fasciitis, dropped metacarpal heads - you name it. I started wearing minimal shoes (including 5 fingers) in my daily life. Now - it's the odd day that I have any foot pain at all. It took a while, but my feet are much stronger and healthier for the change. http://www.rei.com/product/865514/vi...s-shoes-womens are my current favorites.

Bonus: the 5 fingers will very likely last longer than your usual Brooks as there isn't cushioning to break down.

The lawsuit was, as Oak said, related to health claims and whether they were substantiated. That said, with your quite extensive history of injuries, I would definitely talk to a medical professional before jumping in to prevent more injuries.

ETA: I have actually used the Merrell's too - wore out 2 pairs. Personally, I don't like them as well because my toes are too confined for me to feel as grounded. I need to look at other more "normal looking" alternatives for daily life - when time and finances permit.
