I just wanted to pop in and say that I recently picked up a pair of the basic black model. I had been thinking about getting them for a long time, but didn't want to order online. Yesterday, after work, I happened upon a shop that carried a ton of different Vibram models. I immediately went in to try them on, and 20 minutes later I walked out of the store in my new Vibrams!
I've been doing a lot of barefoot walking around outside since summer began, and these come really close to that feeling, while offering better grip, being somewhat protective and a bit more socially acceptable! I absolutely love them and find that it's hard to go back to normal shoes, now.
