I know there are at least 2 other threads on the science behind this, but is anyone here a dedicated barefoot runner? I run about 50 miles a week right now, and today I went for my first barefoot run. I ran a 30 minute route that took me on grass, concrete and 1 mile around a track. As weird as it sounds, it felt natural after only 2 minutes. I sure could feel it in my calves after words, and it really made me focus on my technique. But I was surprised to find the terrain didn't really matter. I could run pretty quick on grass and on the track, but I had a good pace going on concrete too, which I was expecting to hurt. I am striking with the forefront of my foot and not the heel which came natural instantly. I didn't get any blisters, and my feet feel fine. I am still going to wear shoes for a lot of my runs, but I am going to start including a lot more barefoots in my routine as well. Any other runners try this? If not, I really suggest trying it. I got a lot of weird looks from people walking and driving by.
