Out of Retirement

I brought the old shoes out of their short retirement since I finally figured out what was causing the knee problems. In Chicago I started using my new pair of shoes, which of course have a nice tread, as opposed to the worn sole of my old pair. This has happened before, although not to this extent. I realized that the new shoes were causing a change in my gait, which transfers up the leg to my knee, causing the irritation. So today I went for a 3-mile run just to get my legs back in their previous frame of mind, as it were. From here until the marathon I'll be using the old shoes. After that I will break in the new ones appropriately.
