I had been running in Vibram Bikilas for a while, but I was finding that my pinky toe was always getting jammed (and going up a size made it too loose on the rest of my toes). Decided to look for a minimalist shoe that wouldn't result in toe pain, and after reading some reviews I went with these Mizuno Wave shoes. I'm not sure if I'll go back to my Vibrams... these are even LIGHTER than my Bikilas, which is awesome, I can still feel ground details under my feet, and no more toe jamming. 1 star docked because the traction isn't very good on these (which was something I did like about the Five Fingers shoes), and also because I had to go up a full size than usual for a good fit.

As for any minimalist shoe though, make sure to ease into running in these if you are used to a regular more bulky shoe, otherwise you'll likely injure yourself or at the very least end up with some pretty annoying cramping in your feet and calves.
