The current fad is barefoot and minimalist running. Proponents say that we aren’t “supposed” to be running in sneakers because we evolved without sneakers. They say that running injuries are prevalent because of sneakers making our feet weak.
Although I can’t stand the evolution argument (because people apply the evolution argument to everything because it is easy to do) there may be some merit in minimalist running. But perhaps the injury reduction is due to running fewer miles or running at a slower/gentler pace? Maybe it’s not the shoes but how hard the person pushes their body?
