Abstract: An insole (10) is of the type equipped with a face (20) having projections (11-25), suitable for massaging the foot sole, and in particular certain sensitive points thereof, during motion such as walking and jogging. The projections (11-25) made on the insole (10) correspond to points of the foot connected to important parts of the human body in accordance with the general principles of foot sole reflexology. The insole (10) has at least one layer (30) of cushioned elastically yielding material and a thickness (S) set between 5 and 13 mm. The upper layer of the insole (10), or insole shaped, has a first face printed (20) with projections (11-25) towards the above and the second face printed with recesses corresponding to said projections (20?) and is associated to a second layer located underneath (30), preformed with projections (11?-25?) according to a same chart of the first face of the upper layer (20) and made preferentially of latex.
