I first heard this guy on a podcast a couple of years ago and what he said made a lot of sense to me. While I haven't suffered from foot problems, I don't want to either. I have tried to implement as much of his advice as fits my lifestyle, mainly walking barefoot when possible and making better choices about my everyday shoes. This article is a bit lengthly, but if you are interested in learning more about the health of your feet and what you can do to keep them healthy, it is an interesting and informative read.
