More often than not shin splints can be avoided by wearing proper fitting running shoes. I know that was my problem.
Also, depending on how much and how often you run, the shoes will wear considerably. Bad shoes = unhappy feet/legs. If you really want to be serious about running, you need to stay on top of it.
