pounding the concrete can really screw your shins and knees through all the impact, thats why i try and stick to forest/grass land to run on.
a good pair of running shoes with decent insoles helps a bit but sometimes shin pain can be down to the way you run.
I used to run very flat footed and the shock used to give me pain in the shins and shooting pains under the knee cap. By revising how i run from the gait, stride and knee flex i managed to eliminate all of the pain after a few weeks or fine tuning.
