I have been suffering from severe pain in my feet for several years, which has been chronic. Some days they're fine then other days I can't get away from the pain. I have tried pain meds, lyrica, and Anodyne Therapy, but none have helped. I had heard about how well the new Crocks work for foot pain and I decided to try them out. I bought a pair with skepticism and was walking out the door when I saw these strange shoes on the other side of the store. They intrigued me so I asked about them and was told that they are Z-coils designed for foot, knee, and back pain. I tried on a pair and fell immediatly in love with them! I have never had anything on my feet that felt so good! they are ugly as sin but I don't care. As long as they feel good is all that counts for me. So I exchanged the Crocks for the Z-coils and wore them out the door. They were EXTREMELY expensive, but I don't mind that either. They may pay off in the long run. This was done yesterday and no pain at all in my feet, knee, or back! The jury is still out on whether these are the answer for me, but I am more hopeful now than I've ever been on pain relief. Keep your fingers crossed for me.
