I actually prefer the Vibrams Five Fingers (once I finally found the right size).  But I use these in the gym because they give more toe protection while still being barefoot-ish.  The only issue was the arch seemed too high or the width seem too narrow, but it's gotten better.  Perhaps that was due to needing to be broken in a little.  As with all minimalist shoes there is less forgiveness in getting the correct size.  With regular shoes, you can mitigate some size issues by tying them tighter or changing your sock thickness.  But that won't work with this type since it's supposed to be a foot cover without any primary anchor to the foot.  I don't wear socks with these, which makes it simpler to pack, but probably makes last less.
