ABSTRACT:
A midsole, partial midsole, or the like, for inclusion in an article of footwear having a flexible, air-permeable top sole, characterized by at least one plug in the heel region having a thickness (height) sufficient to permit significant compression deformation along its thickness dimension accompanied by simultaneous significant bulging deformation in its circumscribing surface perpendicular to the thickness dimension; the deformations occurring solely due to normal walking activity by any wearer of the footwear; and the deformations thereby providing simultaneously for shock-absorption and ventilation during said normal walking activity.
