I bought the original 5-fingers before they were even popular.  I loved them, but noticed they tended to get a "foot" smell, that even after washing, didn't go away completely.  I don't have athlete's feet, and have never had a problem with foot odor in the past.  I don't have that problem with these, maybe because of the anti-microbial feature, and that is great.  Additionally, I got my original 5-fingers because they were minimalist, but where I am right now, there are tons of rocks, and wearing them was painful.  With these, while it is not an overwhelming amount of sole, it is enough to make it largely bearable, unless you land right on top of a pointy one.  Very comfortable, and fit a bit better than my originals, though the same size (but that is obviously my foot).  Like the color scheme and reflective stuff- useful for increasing visibility. Overall, highly recommend, especially if you are considering hoofing around areas that are not at all urban.
