I used to run daily back in high school (7ish years ago). I am wanting to start running again. I was running on the treadmill a couple of days recently, and my ankles have been hurting. Could this be due to needing new shoes and my current shoes don't have enough support? What else could this be due to? I planned on getting new shoes when I get back from vacation, but I was just curious if it could be due to anything else like weak ankles or something. Before I was running, I have been doing the 30 day shred, and that was when I first noticed my ankles hurting - when we would do the jumpin jacks and such. But it wasn't usually until the end of the workout.
