They've got a few other kinds of minimalist shoes as well. I tried on the Vibrams and they are different for sure. The only barefoot running I've done is on my treadmill. I can only go about 3/4 of a mile before my feet start to develop TERRIBLE blisters from the rough rubber tread. I like how it feels to be barefoot though.

EDIT: So which model did you have, and what did you end up doing with them?
