  • Reinforcing cage embodiments as described herein may provide structural support to the midsole and other cushioning components, thereby prolonging the life of a shoe.
  • a reinforcing cage embodiment may improve durability and reduce material breakdown from excessive compression of the shoe sole materials (i.e., midsole, additional cushioning components).
  • the rib apertures of the reinforcing cage embodiments may be cut away form a structural "wall" (e.g., shapes resembling that of an "S", "Z” or a triangle) to encase the sole materials and provide a reinforced structure to support the rearfoot region of the runner.
  • These structural walls may aid restraining and counteracting the outward swelling of shoe sole components (e.g. , midsole, other cushioning components) and allow the sole to remain compact in its optimum form, thereby extending the life of the shoe.
  • Apertures of the reinforcing cage embodiments (e.g., in the third portion) may provide for weight reduction and greater flexibility for the footwear item. Additionally, the reinforcing cage embodiments may provide supplemental mechanical cushioning to the midsole and support during mild pronations.
  • Another advantage provided by the reinforcement heel cage embodiments described in the present invention may be that since the reinforcing cage structure extends into the midfoot arch area, it may act as a support shank enhancing foot stability.
  • An additional advantage provided by the reinforcement cage may be that it
  • the wall (including the aforementioned ribs) of the reinforcing cage itself has a structural integrity that may counteract the weight of the wearer, and may serve to return energy as well.
  • the shapes, structure, and component materials of the wall may be chosen to optimize impact attenuation and energy return.
