Abstract

Abstract There is disclosed a heel construction capable of providing an optimal response for an individual wearing a shoe to which it is attached. The construction is adaptable to being permanently or detachably fixed to a shoe having an upper section and sole section which extend in a generally horizontal direction and form a toe area at one end and a heel area at the opposite end. The heel construction comprises a generally Z-shaped resilient plate the upper arm of the plate extending towards the toe area and the lower arm of the plate extending towards the periphery of the heel area of a shoe to which the construction is fixed. There may be at least one supporting shaft disposed in a transverse direction between the upper arm and the middle arm of the Z-shaped plate and at least one like shaft disposed in the same direction between the lower arm and the middle arm thereof, the shafts being located at the junctures of each of the upper and lower arms with the middle arm of the Z-shaped plate and, as well, vertically disposed springs disposed transversely betewen the arms at a distance from the junctures of the upper and lower arms with the middle arm.
