Is it me or is the Rhythmic Step causing havoc on some people's feet/ankles. I have come down off the step twice now and have pulled tendons and ligaments. I actually thought I broke my foot the first time. I have been stepping for over 10 years and have not had trouble with any other video(Now, I know you must think I am a clutz! :-wow )So I went out and bought specialty sneakers now for better support at 120.00/pair. Lets see if that helps. Am I the only one with this problem??? Any suggestions???
