A shock-absorbing sole for footwear comprising an assembly of shock-absorbing modules placed side-by-side and arranged in the longitudinal direction. Each module includes a wire-shaped element made of a selected material of relatively high strength and rigidity folded in such a way as to form a succession of upwardly-pointing loops lying in a plane that passes through the longitudinal axis of the module and at right angles to the outsole. The loops are inclined in the same general direction so that whenever the sole contacts the ground, each loop bends with a compliance that depends on its relative length and, thereafter, tends to regain its original condition by means of a relatively quick return with what is substantially a damped aperiodic harmonic motion. The greater or lesser compliance of the assembly depends also on the greater or lesser transverse density with which the modules are arranged.
