I've run in Five fingers, but these are better!  My goal is to be fast runner, not a barefoot runner!  These are light and barely there, but have enough under foot, so I'm not dodging every pebble and searching for my next good placement!  That said, I bought my normal 11s and they were almost too big!  So if your between, go down!  First run, 1 hour, no problem s and a 2 minute PR! The colors are great too!
