A great anecdotal discussion about overuse injuries from Pete Larson @ RunBlogger. My own experiences pretty much match what Pete details here, with the slight exception that I think my recent injury was actually due to a problem with my hips. Interesting thoughts about cycling your shoe wear. I don't wear shoes often, but as we enter winter I'm contemplating shelling out for a pair of Vibram Bikilas - my classics are looking very sad.
