Is it possible to sprint barefoot, no minimal shoes what so ever; on any surfaces man-made or natural? There lots of evidence that humans are able to run on a lot of surfaces at a controlled pace. However, I never heard a person sprinting down their street to get away from a dog. When I mean sprint, I'm mean turning into Usain Bolt in the 100m. It wouldn't make sense if we couldn't sprint for our lives if a saber-tooth was on our tail. Any answers and or opinions are welcomed , that who you be.
