Running shoe woes

I thoroughly enjoy my evening runs, and tonight I had my first night run in over 2 weeks. I was feeling great! My heels were a little sore, but I thought nothing of it. When I returned, I bounded up my stairs into my apartment. Upon streching I looked at my heels for the first time and discovered that they were not doing as well as the rest of me. I'll ducktape them up, and they'll be fine tomorrow. My shoes, however, have a new touch of red... nice.
