Interestingly Kenyan marathon runners don’t get navicular injuries and they run for thousands of kilometers in bare feet.
There is some interesting research around to suggest the more you wear super supportive runners the more likely you are to get foot injuries because the foot no longer has to, or can do what it’s designed for. Also you loose propreoception between the foot and the ground leading to different running style (longer stride length and increased rearfoot strike) (studies of those with rearfoot strike versus forefoot strike report far greater injury rates in rearfoot strikers) when you then put on footy boots and no longer have the full support and cushioning of your runners, the loads in the foot can be through the roof. As the body works in a use it or lose system the runners are in effect weakening the foot muscles and also forcing you to walk differently.
another study looked at injury rates in fitness runners pre and post the inception of the early Nike running shoes. Prior to that Dunlop vollys were the most popular running shoe (and we all know how little support they have). Injury rates went though the roof after the “modern” Nike’s became the norm.
There are many sports dudes now training athletes in other sports in bare feet with great effect. Problem is in footy you have to kick a ball on the soft top part of your foot so some form of footware is necessary for some of the time.
From my own experience I had plantar faciatis for 15 months and did everything the physio told me to do including wearing expensive shoes, ortodics, inserts, heal raisers etc and nothing was helping. At the suggestion of the S+C coach that I employ for my atheletes, I made one change to cheap ($80 versus $200+) Under Armours with bugger all support in them and the problem went away within weeks with no other change to what I was doing.
Edit: ignore the change in font size, no idea why that happened.
