After a comment by rlwimi, I was compelled to look into these (and I use the term loosely). I seen nothing but praise for them and really want a pair now. I figured I let reddit know about these neat looking things.Another runner also fully endorses these bad boys, as does Barefoot Ted, who has run marathon mountain trails and the Boston Marathon in them.While I not fully convinced that barefoot running (and walking, I plan to use them as daily out and about shoes) is a panacea for foot injuries, I think it might be worth at least one generation of shoe for me to try it out and see what it like. The argument that we evolved together with our feet and that barefoot movement is good for us seems compelling to me. Then again, we did invent shoes, mostly to protect our feet I imagine. These seem like a nice compromise.Lastly, head to the Vibram website if you want to buy them.Disclaimer: There is no disclaimer. I not affiliated with them in any way. I think the Nike Free Run shoes just look cool and wanted to justify wasting a bit more than an hour looking up this stuff. : pI just got a pair this weekend after reading about the barefoot movement.Just ran my first time in them. They are extremely comfortable. They fit snug on the foot so that the foot does not shift inside the shoe, which used to hurt my feet and cause blisters.They do a great job of simulating the barefoot running experience. You feel very light and not restricted at all, and you can feel Nike Roshe Run your toes really flexing and pushing you along, which is something you just don get from normal Nike Roshe Run runners. The soles are just thick enough that you can run on pavement, gravel, grass, just about anything. I stepped on the pointy end of a bigger stone a few times and it hurt, but not enough to cause an injury.The biggest thing I noticed was my muscles! After about a mile and a half I could feel the muscles in the back of my leg near the Achilles tendon and up to my calf being worked. By the time I got done my run and took them off, the back of my leg from my heel all the way up to my calf was tight. I can definitely tell that I am working muscles I had not worked before.
