Shoes are good....happens in all pairs I have. When I try do sprints I warmup and stretch, otherwise in the gym the treadmill is my warmup walking at about 2.8 for ten minutes then switch to the elliptical for 20-30. Do shin splints affect the muscles down around the ankle and interfere with foot flexion?
I do have pretty large calves and have always wonder if this is caused by some sort of muscle imbalance, but what the hell do you train the tibia muscle with?
