I don't know what to do. The thing has gotten to the point that I can't run anymore w/o crying. I have decided to stop running for 1 month to give it time to heal a bit. I was planning to take a break in october after my last tri, but it seems it won't wait that long. I have been without a run for almost 2 weeks and i'm going mad. Has anyone heard about these z-coil shoes? They are supposed to absorb shock to the heal. Thought they might help. Has anyone ever ran in them?
