Abstract
A walking sole for sports shoes, particularly golf shoes, having, on at least one of its lateral edges, a series of substantially transverse grooves, filled with a material having a degree of elasticity superior to that of the material making up the sole. The grooves are provided in the front portion of at least one of the lateral edges (1a,1b) which extends the length of the frontal area of the sole (1) which provides support for the front part of the foot of the wearer of the shoe, and they mark the boundaries of at least one flexible tongue (7) transversally around an axis of flexion (X) joining the internal ends of the grooves (3). (FIG. 1).
