John Deere has introduced the MagneForce line of work boots with magnetic insoles in the boot’s actual construction. Users can take advantage of the benefits of magnets without worrying about the hassles of application. The magnet power emanating from the insoles penetrates the wearer’s foot to a depth of two inches, increasing blood flow, bringing natural pain relief, and stimulating the wearer’s energy level.
