Embodiment Construction

[0047]The natural motion of running, whether male or female, can be divided into two distinct segments; the heel step followed by the toe step. The heel step is more time concentrated and therefore provides a significant instantaneous impact. The subsequent toe step is a time-gradual, weight shift rolling motion, which is devoid of any significant impact forces. The present invention comprises a shoe and / or a shoe system that counters the initial and harmful heel step impact.

[0048]As shown in FIGS. 1, 2 and 3, in particular shoe embodiments, a compressible air bladder 12, comprises a rear containment portion 10, preferably extending from the rear heel of the shoe, and a forward containment section 13 extending into the toe portion of the shoe, which acts to significantly dissipate the energy of the heel step impact. The maximum impact point on the bladder 12 is shown as impact point 11. Another embodiment of the bladder is shown in FIG. 15. In preferred embodiments, bladder 12 exten...

Abstract

An improved running shoe is disclosed that dissipates the impact forces of the heel step by utilizing a pressurized inner bladder designed for bi-directional collapse. The shoe comprises a rear portion for accommodating a heel, a forward portion for accommodating toes, a shoe sole; and a compressible bladder. The compressible bladder is preferably contained within said shoe sole and partially inflated. The inner bladder has a heel portion extending proximate to an outside end of the rear portion of the shoe but tapered inward at the impact point and a toe portion extending proximate to an outside end of the forward portion of the shoe. The inner bladder collapses at the heel upon the initial heel step, significantly reducing the heel step impact forces. The heel step section of the inner sole is then re-pressurized utilizing the natural forward motion of the toe step. Preferred embodiments of the shoe include accordion pleats around the heel and a rounded heel to further dissipate impact forces.
