It claims to remove body toxins from the body.There may or maynot be any truth or scientific evidence to prove this as a fact however, oriental medicine has been around for hundreds of years and cannot be overlooked. To answer your question "will they save your sole?" It would be great if you mention what you believe the problem with your sole was to begin with..?

An NPR experiment on Kinoki foot pads tested to see if they'd drawn anything out of a reporter's body. Reporter Sarah Varney and her husband bought some “detoxifying” Kinoki foot pads and wore them to bed. In the morning, they both awoke find the pads covered in the brown mess that the advertisement had promised. But when they took the foot pads to a lab and had them analyzed and compared with unused pads, the used pads were almost identical to the blank. Further experimentation showed that the “gunk” in the pads shows up if you hold the pad over a pot of boiling water. Who knew steam had "metabolic waste"? Sources: · The Consumerist August 19, 2008 · ABC News April 11, 2008 · MSNBC June 19, 2008 The Kinoki foot pads -- as well as other brands -- promise to draw out everything from heavy metals to metabolic wastes, toxins, parasites, cellulite and more, to restore your vitality and health. Toxicology Lab Found No Toxins in Used Foot Pads Like reporter Sarah Varney, 20/20’s correspondent John Stossel also took used pads in for toxicology testing. And, like hers, Stossel’s results came back negative. 20/20 asked NMS Labs, a national laboratory in Willow Grove , Pa. , to analyze used Kinoki and Avon pads from eight volunteers. They tested for heavy metals, including arsenic and mercury, and 23 solvents such as benzene, tolulene and styrene. None of these common toxins were found in the used pads. So what’s that brown, foul-smelling gunk? It’s just a natural reaction between the ingredients and the moisture from the bottom of your foot. Exposing the pads to moisture, either by placing them over a steaming pot of water, or putting a few drops of water on them will make the ingredients turn a darker color and emit an unpleasant odor. Dr. Devra Davis, director of the Center for Environmental Oncology at the University of Pittsburgh and an expert on toxins, also conducted a similar experiment on her own, leaving the pads out overnight without their protective packaging. In an article for MSNBC she stated the pads contain “little more than green tea and vinegar,” and that the color and odor are likely the result of these ingredients “interacting with oxygen, heat or moisture.” 20/20 asked Avon and Kinoki for scientific test results showing the pads do what they claim to do, but neither company fulfilled the request.
