ABSTRACT:
A shoe construction having an energy return system together with features providing cushioning and stability. The energy return system includes a rigid frame having a torsional rigidity bar in the midfoot area integrally connecting annular walls in the forefoot and heel areas of the midsole. A net of monofilaments or fibers is secured under tension in the areas defined by the annular walls with the net positioned over an open area in the midsole. A cantilevered system of support pads is positioned in the arch area to support the medial side of the midfoot.
The energy return system also includes a rigid frame having annular walls in the heel area. A net of fibers is secured under tension in the area defined by the heel annular walls. The open areas can have inserted within them a variety of inserts to view the components of the energy return system from outside the shoe.
