I have practiced as a podiatric physician in Seattle for 26 years. Six years ago I was introduced to the Z-coil pain relief footwear. I was so impressed with the results I was getting with a small sample of patients, that I started recommending them especially for plantar fascitis. I personally own six pairs and have received a lot of relief from back pain. I was so taken with the shoes, I decided to become more deeply committed to the product. It has been very rewarding to see the amazing results at the office and the shop relieving foot, leg and back pain.
