The heels definitely help. Heels take pressure off that heel spur. I do ok with walking shoes, but I notice the difference when I where heels to work. I'm not going to wear heels at home that's for sure!
Sue, how is the ballet class going? I'm working out still and am having very little problems with my heel. Of course, I'm only doing 10 minutes of stretches followed by my bike for about 15-20 minutes.
