I've walked duck footed all my life, my left foot is really bad. it points at I would say an angle of 30-45 degrees, while my right one is about 15-30 degrees. I was wondering if this is bad for my feet, or any other part of my body. I will also occassionally walk on the balls of my feet instead of using my heel. this doesn't happen all the time, only occassionally. Again, is this unhealthy? Should I tell my doctor about any of this. Thank you for your help.
