I decided to try these magnetic insoles in my slip on shoes since they have almost no support and I need more to help with my back issues and fibromyalgia. But they didn't work for me. The magnets fell out when I took them out of the packaging, but they popped back in to place easily. But they hurt my feet. The acupressure bumps and nodules on the insoles were quite painful for me, and the magnets felt like I was walking on rocks in my shoes. I made it from the house to my car in the garage and then felt I could barely walk and had to take them out. They hurt horribly. I have never had sensitive feet, but this was simply too much for me to handle. Try it for yourself if you have hard feet, but for me, no thanks.
