I bought a pair of magnetic insoles and they make a difference in how I feel during the day. It's strange because there are days when I begin to question whether it's working or not, but the pain that disappeared almost immediately confirms that magnets are great. I bought a pair of the nikken magnetic insoles. I did not buy the one with far infrared, just the one with nodules. If you don't like the feeling of nodules underneath your feet get the ones with far infrared in it. Hope that helps.
