Better shoes. Mine are fairly flat, no issues. Though now I'm starting to have a hip issue. I was certain that was for old people..... hmmm......
You know I've been to Big Peach Running and did the whole analysis thing and brought some shoes but didn't like them. The shoes I do the most running in are NB trail shoes and they are falling apart. I know the Marines issue NB or they did and I think I need to try some new New Balance shoes.
I also have a torn ACL and meniscus in my left knee and patellar tendonitis in my right knee.
