Incredisoles are a one-of-a-kind liquid-filled orthodic. The liquid core-fluid automatically flows to the area of the foot that needs the most support. The memory control system forms to the unique shape and contours of the foot, unlike other insoles that force the foot to conform to the shape of the insole. Bio mechanically placed pressure points make for extra comfort and help to energize tired feet, reducing foot, knee, hip and back pain by reducing stress on joints. Incredisoles can be placed in the freezer, then into your shoe for a cold therapy treatment. Incredisoles are hand washable only.
