Wow! Fantastic response Max! I agree that it could be a sign of something off in your gait or the way you distribute weight. That wouldn't be a problem with rubber souls, but with a real leather shoe, it becomes a problem. In addition, if it is something persistent in your gait that is a problem, it could eventually lead to similar wear on your hip or ankle joints, which is a bad deal. (My sister, who has one leg shorter than the other, had to have a hip replacement at the relatively young age of 50 despite having a lift in her shoe for most of the past 30 years. She is in much less pain now, but will probably have to have the replacement redone in 15 to 20 years. Expensive, not to mention that any surgery is always a risk! No fun!)
