SHOE SOLE CONSTRUCTION ABSTRACT A shoe sole having a tread defining a longitudinally orientated concavity with the lower extremities of the sole embodied in downwardly and outwardly disposed flex- ible lugs to cushion the foot against impact loads. An imaginary plane containing the lowermost points of inner and outer lugs, adjacent each side of the sole, inter- sects a projection of the sole edge at an acute angle. Accordingly, the lugs may readily flex relative to other sole components for cushioning purposes. Rows of lugs spaced inwardly from the sole edges are of a lesser vertical dimension than the outermost lugs and serve to supplement cushioning. A web extends between some of the outer lugs to reinforce same against load deflection. Further, the outer lugs may be of non-uniform lateral dimension at the heel portion of the sole.
