Abstract: An insole for a shoe, which massages the reflex zones of the sole of the foot, has a flat basic sole (1) which matches the contour of the shoe and cushion-shaped elevations (5) associated with the reflex zones to be massaged. The elevations (5) are integrally formed on the basic sole (1) and consist, like the basic sole (1), of elastic foamed material having a Shore A hardness of 30.degree. to 45.degree.. The height of the summit region (7) of an elevation (5) above the upper surface of the basic sole (1) is one to two times the mean thickness of the region of the basic sole (1) adjacent to that elevation (5). This insole is easy to manufacture and has optimal massage properties.
