Marsye-The Z Coils are so easy to walk in, they're not like walking in heels even though they do have a spring in the heel. I suffered for 5 years with heel pain so bad that I could barely walk, I don't have plantar fascitis(sp), heel spurs, bone spurs, etc., they didn't know what the problem was. I had the lovely cortizone shots, which helped somewhat for about a week. The thing is, you can only get a very limited amount of shots during your LIFE and I was at my limit. I had asked my doctor about the Z Coils and he said that my feet needed support and blah, blah, blah. They could do surgery though. Excuse me, you don't know what the problem is, so you're going to do surgery? Not on me, you won't. I got the shoes and within 3 days, my feet were feeling so much better and haven't bothered me since.
Hope you find your solution.
