It doesn't work. Spend a lot of money to buy a plastic insole, it is better to step on the pebbles in the community yourself, and the effect is the same. A pyramid scheme has been exposed by CCTV, waiting for these deceptive birds to be captured alive. After my father bought a pair, he went crazy. He gets up every morning to take his blood pressure, and has changed two sphygmomanometers. Unless there is something wrong with the sphygmomanometer, he goes to the hospital to get it. He thinks that putting on insoles should cure high blood pressure immediately. Why not? It doesn't matter if you are cheated of some money. There are also rumors that it has the function of curing all diseases. The company's trademark is used in drinks and cosmetics. The patent number is just a prop for massaging the arch of the foot. Then the MLM organization fabricated all kinds of lies to trick its subordinates into joining the company.
