A few years ago I started getting terrible pain in my feet, mostly in my heels. My dr. told me I had heel spurs. She told me to wear insoles, which I do but they still hurt really bad. During the summer, I wear only flip flops and my feet don't hurt at all. Today was the first day I wore tennis shoes (with insoles) and my heels still hurt. It doesn't seem to matter what kind of shoes I wear. I've tried Nike and New Balance thinking they would be the best but it doesn't help. Anyone have any advice?
