Firstly, on surface facing foot, the insole made up parallel, mobile blocks, supported by springs (preferably spiral springs) varying stiffness in ratio 9-4-5 corresponding respectively heel, plantar arch metatarsus), housed inside cavities in rigid or semi-rigid sole. Secondly, ground, situated an outsole (integrated by glueing molding), elastomer having three protrusions connected transversely, first be­ neath joints, second under metatarsus third heel. group containing cavities, blocks is kept reciprocal position, but upwards, an annular welt, molding attached to means polyamide screws may be removed at will.
