Advice for Shin Splints?

I’ve had shin splints on and off for a few years and they are a real pain when I play soccer. I used to have a muller brace/wrap that worked decently, but my CrossFit trainer just told me about tapping my toes while watching tv (etc). His theory is on prevention and building up the muscles. Anyways, I want to hear your take on it and what ever advice you can dredge up on the topic!
