I have been writing and debating a lot on ‘overpronation’ in the last year or so. There are so many myths and misunderstanding of it. The interpretation of what it is and what impact it has and how you manage it is certainly driven by what agenda or narrative those writing about it have. The Dunning-Kruger effect is strong in some of them (see this take down I did). Some want to argue that ‘overpronation’ is not a problem, yet the two most recent systematic reviews of all the evidence show that it is a small risk factor for injury in runners. Even though it is small, it is still statistically significant. Who would you rather believe? A blog post of the more systematic review of all the evidence? Others have the one treatment for all approach, but that is an epic fail as the are many different causes of ‘overpronation’. You treat what is causing it. There is no one treatment or approach that is best due to their being many different causes. There is so much bad advice and some good advice. I try to address the myths wherever I may be writing.
