Turns out, the more shoe you wear, the worse it is for you.  The NY Times just published this article on motion control shoes.  Apparently someone in the Army asked if all that motion control in shoes was necessary.  Turns out, the better the motion control in a shoe, the more likely you are to get injured.  In other words, the more you let the shoe create the stability and the less your foot has to do it, the more likely you are to get injured. If you’ve ever run barefoot or in minimalist shoes, it becomes apparent pretty quickly how much more your foot has to work to create stability, but also how much more relaxed your foot has to be. Balanced tone, always leads to greater function.
