Abstract
Abstract A shoe sole including an outsole (5) and an insole (1). The latter includes a plurality of ribs (2) which run along the entire width of the sole, are directed transversely relative to the longitudinal direction of the sole, and are covered at the side facing the foot (10) with a perforated base layer and possibly a covering (6) of leather or fabric. The ribs (2) include a base part which has approximately the shape of a trapezoid, whose shorter base is at the bottom, so that grooves (3) occur between the ribs (2). The insole (1) is located on the upper side of an outsole (5), which upper side faces the foot. The special shape of the ribs (2) results in a reinforced reciprocal rolling effect and consequently in an improved massaging and foot aeration.
