ABSTRACT:
A dynamic dual density heel bag for use in shoe construction and typically employed in athletic and walking type shoes. The dynamic dual density heel bag includes a construction including a lower flexible sealed enclosure containing a high density material where the lower enclosure has a V-shaped top surface. Also included is an upper flexible sealed enclosure containing a low density material. The upper enclosure has a V-shaped bottom surface for being vertically cradled by and affixed to the V-shaped top surface of the lower enclosure for forming a heel bag. The heel bag is then affixed within an outsole of a shoe typically with an adhesive. The high density material of the lower enclosure is isolated from the low density material of the upper enclosure. Thus, the low density material of the upper enclosure provides cushioning and shock absorption and the high density material of the lower enclosure provides support, security and stability to a foot. The lower enclosure and the upper enclosure of the dynamic dual density heel bag can contain high density silicon and low density silicon, respectively, and each can be comprised of plastic. Further, the upper enclosure can be affixed to the lower enclosure as by heat sealing or adhesives. In an alternative embodiment, the dynamic dual density heel bag can be modified to support the entire sole of the shoe in addition to the heel area.
