Since I ditched the running shoes, road running is silent. Grass running is liberating. Track running turns my feet rather orange. Running in the rain is incredibly satisfying.
Overall, it's been great. Stepping on sharp rocks is a bit painful. I've gotten blisters, but they never go deep. I've walked barefoot most of the time since February to help my feet harden. I imagine that kind of preparation is probably necessary.
So I highly recommend being barefoot. :)
