I have been running for about 3 weeks now trying to get in shape for basic, I was running in an old pair of shoes I had (I know it's a bad idea) and they seemed to be working fine till about 3 days ago. I ran 3 miles, the entire time I was running I could feel discomfort in my ankles, I thought it was just because it was cold out, after I got done running and walked around a bit, I sat down for not even 5 min. when I stood back up, my ankles were hurting so bad I was limping everywhere. I bought new shoes the next day, took a day or two off from running, but I ran again lastnight, in the new shoes, and my ankles are killing me again! Is this going to go away and is it bad?
