A sole pattern for shoe soles of elastic yielding material comprises projections whose cross-section decreases in a direction at right angles away from the sole. The projections are associated as projection couples in such a way that the tread surface of one projection is sloped inwardly toward the sole and the tread surface of the other projection is also sloped inwardly toward the sole, while the component of the inclination on a level of the sole is oppositely directed.
