I've read a lot on potential injuries and how to avoid them, and one of the things I've read in several places was that sore calves is a sign of overstriding. I was wondering though, could it also just be a symptom of bending your knees while running? I'm reading Barefoot Running Step by Step, so after reading "bend your knees" several times, I decided that perhaps I should try bending my knees. But when I do so, even just standing, I feel my calves engage, so it seems that running like that is going to make them a bit sore, at least at first until they get used to being used. Am I completely off on this?
