|Area of pain is circled with my mad paint skills.|
What exactly causes it, I'm not too sure, and I haven't read anything so far that explains it, but I will be searching to find out. I have heard that for whatever reason the strap on the KSO's can contribute to the pain so I guess we shall see as I run more barefoot instead of in my Vibrams.
If anyone else is reading this and has some helpful hints, please comment and let me know what all I can be doing to help prevent this from happening. And of course I will post more updates as I figure out more things.
