Many injuries and ineffeciencies in running bio-mechanics come from postural imbalances, where one leg is moving, absorbing forces, and propelling forces differently than the other. Though gait-retraining is a possible corrective action, we prefer runners to first work on balancing out the tension levels in the key major-movers of the hips - namely the lower back, glutes, hamstrings and quadriceps. If these areas are balanced and the mechanics are still off, and/or the symptoms still remain, we can now more safely move into gait-retraining. Given this, it is highly recommended runners first spend some time identifying any imbalances in tension on the foamroll.
On a foamroll, while focusing on one leg at a time, track your sensitivity/tension levels on a chart. Do one side, one leg at a time using a high density foamroll on a hardwood floor. Use a number system 0-10 with 0 being no tension, no discomfort, and 10 being something too intense/painful for you to handle. Perform a similar test with your hands/thumbs/theracane for the calves and shins - as instructed below.
