I know a few people who have tried the barefoot running thing and think it's great. I will say it is definitely different than what I expected. Even running on concrete didn't hurt my feet, though the next day my feet were just a little sore. Even though I run regularly my calves were somewhat sore the day after running for the first few uses, but since barefoot running is suppose to change your running style and make you land more on your forefoot that is to be expected. The shoes themselves seem good quality and have stood up the first few weeks of use very well.
