Last Thursday, Emily called and asked me to come over and go running after work. I agreed because it was still warm out and I happened to have a pair of tennis shoes with me. Unfortunately, they were my most worn-out pair. We ended up running about 3 miles and the next day my heel started hurting. It is still hurting today with every step I take. I'm not sure what my injury is called, but it's pretty painful.
I even took the inserts out of another pair of tennies and put them in my new boots so they were more cushie for my footsies.
