  • Patent number: 6584705
    Abstract: A shoe having a simplified construction includes an upper layer having a top edge and a bottom edge for enclosing a foot. An inner lining layer is joined to the top edge of the upper layer for providing comfort. A counter component is positioned between the upper layer and the inner lining layer for supporting a heel of the shoe. An outsole wall having a slanted inner surface for forming a cavity therein is joined to the bottom edge of the upper layer. An insole for supporting the foot is shaped to include a slanted outer surface for fitting within the cavity formed within the outsole wall. An outsole is joined to a bottom of the outsole wall and the insole for contacting the ground. In an alternative embodiment, the outsole wall includes a vertical inner surface for forming a rectangular-shaped cavity which accommodates a rectangular midsole filler layer.

  • Patent number: 6115944
    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.

  • Patent number: 5950332
    Abstract: A fluid circulating cushioned insole for a shoe includes a base panel and a top panel. A series of three cavities are molded into the panels including a heel c, an arch cavity and a metatarsal c. Three channels connect the cavities for circulating flow from the heel cavity to the arch cavity to the metatarsal cavity and back to the heel c. Each channel is equipped with a one-way flow valve constraining the fluid within the cavities and channels to uni-directional circulating flow to massage the foot during each step. The foot is also ventilated during each step by providing an open-bottomed pump cavity in the bottom surface of the base panel, which cavity is connected by at least one open-bottomed channel extending forwardly into fluid communication with a series of vent holes through the base panel. A matrix of branched channels connect each of the vent holes to the longitudinal channels.
