Abstract (en)
A sole for the realization of therapeutic, sport and free time shoes, comprising an air tube provided between an upper layer (2) and a lower layer (3) for the presence of distancing elements of elastic kind, like small full or hollow pistons (1), of equal or different diameters and, eventually, out of materials having a different resistance so as to allow, in the space movement of the load from the heel to the heads of the metatarsi, a gradual adaptation to the resting according to the needs immediately expressed by the foot, maintaining the harmony between the agonist and the anthagonist muscles. In a variant, said small pistons (1) may be replaced by elastic bands (6) out of rubber, para rubber, plastic materials and similar.
