top of the toe area on only my left shoe always wears out incredibly fast while there is no wear on any other part sof my shoes. I also have a tight/locking eeling in my low back only on the left side...and IT/Quad probs on my right side. What the hell is going on?
bump
leg length discrepancy
Had similar problems and found out it was a leg length discrepancy, only it was "acquired" from always running on one side of the road. Experimented with stretching & strengthening to fix the problem, then changing sides every 5-10 minutes on a loop course (when practical), or changing sides half way through on an out and back. Problems and irregular shoe wear pattern have disappeared. E-mail me if you'd like more info.
Best of luck to you!
