I just wanted to write to tell you how pleased I am with my Happy Feet insoles. I immediately felt a relief of pressure in my lower back. More importantly, I have Type II diabetes and had suffered from leg and foot cramps for several months prior to purchasing your product. I am happy to report that I have not had a single cramp since using your insoles. After work, I no longer have red toes and my feet don’t feel as hot. I am completely sold on your wonderful product and I have told several other people with diabetes and otherfoot/leg circulation problems. Thanks so much
