I have a related question.
In the past, every time I tried to train for a 10k or anything, I would end up with lower back pain and shin splints. A friend of mine told me to try striking more on my forefoot and less on my heel, and the transition cured my back pain but not the shins. I've been wearing Mizunos for over-pronation and whatnot.
Running more on my forefoot brought on a whole new problem, however. Before my shins can even act up, I get calf soreness and tightness. I only got that pain after increasing the mileage to ~20 (I cross train a lot and have never been able to run a lot because of shin splints and now this).
So I decided to try Vibram Five Fingers, and so far no shin splints or back pain. However, my calves are getting torn up. Each time I run (usually about 3 miles), they get incredibly sore, tight, and tender for at least 4 days. What the hell? Any suggestions for me? I've had the VFFs for a month. I'm ready to f***ing run for once in my life, and not have to deal with this shit.
