"It soon became clear to the researchers that most of our beliefs about running injuries and shoes are, in fact, myths.
Pronation, for instance, does not seem to be a problem requiring correction. In the one large-scale experiment studying pronation, almost 1,000 novice runners, some of whom pronated and some of whom did not, were given the same running shoes and followed for a year.
At the end of that time, many of the runners with normal feet and form — who did not overpronate — had become injured, but a much smaller percentage of those who overpronated had been sidelined.
Dr. Nigg and his colleagues write in their review that this finding suggests “that a pronated foot position is, if anything, an advantage with respect to running injuries.”
Similarly, they found little evidence that forcefully striking the ground causes injuries or that changing or removing your shoes alters those impacts much anyway.
Perhaps most unexpected, running shoes designed to somehow “fix” someone’s running form turned out often to be ineffective and even counter-productive. In a series of studies, when military recruits were assigned running shoes meant to control their particular level of pronation, those soldiers were as likely, or even more so, to sustain running-related injuries than soldiers given shoes at random"
