In conclusion, I'm not some fanatic saying everyone ditch shoes now. Chances are you've been running in shoes for 20 years. Your bodies done some adapting during that time. You've got to gradually change if you want to undue some of the changes.
The purpose of this article wasn't to talk about the benefits of barefoot running. Instead it was to point out the problems with Running Shoe classification. It's based on a cushioning/pronation paradigm that simply is not as true as they want us to believe. That paradigm needs to be reevaluated. It's not founded on good science but rather initial ideas that made sense with no science behind them, but upon further review may not stand up to testing. A recent study found that using the good old shoe classification system that everyone uses, had little influence on injury prevention in a large group of Army Basic Training participants (Knapik, 2009). They concluded that selecting shoes based on arch height (like all major running magazines suggest) is not necessary if injury prevention is the goal. I guess that means the systems broken...
Where do we go and how do we fix it? I have no idea. Sorry, no genius answers here. My inclination is that we aim for letting the foot function how it is meant to function, or at least come up with some shoe that may alter foot mechanics but while still allowing feedback/functionality of the body. The first step is looking at the foundation on which running shoes are built upon, the motion control, stability, and cushioning paradigm. My take is that it needs to be reevaluated. I'm going to end with something I've already said, but it's an important concept to get across:
The body is more complicated and smarter than we give it credit. The type of shoe and material of the shoe changes impact or stride characteristics NOT because of alignment of the lower leg or because of changes in cushioning. Instead it changes impact and stride characteristics because it alters the sensory feedback. The brain is a wonderful thing.'
