Okay, I will jump in here as a runner to offer my opinion. I ran D1 in college and was an NCAA all-american in cross-country and the 10k on the track. My marathon PR is 2:21. Here is the deal with these shoes. If you are not (even slightly) overweight and plan to run on only grass fields and packed dirt trails, go for it. When I was training hard I would commonly do around a mile and a half of barefoot speed work ON THE GRASS INFIELD after our track workouts. If you think the human body is capable of safely running barefoot on cement and asphalt, you are nuts. If you think the average joe can run barefoot while carrying 10 or 15 extra pounds, you are crazy. I spent a year in California training with some of the top distance runners in the world, many from Ethiopia and Kenya. Sure, these guys grew up running barefoot. Their bodies are also VERY different from most of ours. Lets not forget they ran on DIRT roads and DIRT tracks, not pavement. If you are 5'6" and weigh 85 pounds, you can probably pull these things off. If you are 5'9" and weight 196, you are asking for injuries, even if you do stick to the grass. It is true that our bodies are meant to run barefoot, that is a no brainer. But, it is also true that we are not meant to be overweight, we are not meant to run on hard surfaces and we are not ALL meant to have the bodies capable of running long distances (survival of the fittest). We are all different. If you wear these and enjoy them, fine. Be careful that you do not develop a stress fracture. If you are going to go minimalist, I think you would be better off in a pair of lightly cushioned racing flats. That is just MHO.
