Many of our runners are a passionate of the barefoot running movements. They really insisted that wearing shoes and hard surfaces while running are the cause of all evil and that the only salvation is running barefoot on soft surfaces. Trying to argue with them is just like trying also to argue a religion. There was accumulating evidence that running wearing shoes will always protect the foot from any sort of injury and not cause it. Runners who really loved barefoot put interesting spin on their interpretation of this evidence and are very much selective in what they choose to acknowledge. So a number of running shoe companies are tapping into this movement and they produced running shoes that mimic barefoot running.
