Could also be caused by tight hamstrings...the only way I am able to get my hamstrings stretched to my satisfaction is to have someone stretch them actively with me. I had it done today by my therapist and I feel like a million bucks. Tight hamstrings would pull your ankle up as well because it can't get the length it needs to let your ankle touch the ground.

I jammed my ankle last Oct and am still trying to get it to work right. It's finally getting there. One of the things I have to do is invert/evert the ankle on the balance board as well as calf strengthening exercises. Here all this time I thought mine were strong enough from riding. I guess I thought wrong. The assessment exercises they did were ridiculous. I was ashamed and said quietly, "you do believe me when I tell you I ride 37 miles round trip to work?" The therapist goes..."we had a guy in here that rides centuries at least twice a month and you did better than he did" Made me feel a little better
