Abstract
The present invention provides an unique improvement in foot cushioning constructs and shock absorbing systems for a constructed article of footwear to be worn by a person. The invention employs a deformable and re-formable elastic stretchsole joined as a planar sheet to the perimeter edge of the shoe upper and forms an elastic end closure for the shoe upper; and includes not less than one pre-positioned median cavity able to receive at least a part of the deformed elastic stretchsole layer and cushion the compression forces generated thereon by a person's foot. The foot cushioning construct and system provides a trampoline effect that will lessen the impact on the foot and create greater comfort for the wearer of the shoe.

In a constructed article of footwear to be worn by a human person which includes at least a shoe upper having a perimeter edge for housing the human foot and an outsole joined to the shoe upper which serves as an exterior bottom for the article of footwear, the improvement in foot cushioning comprising:
- a continuous, uniform, planar elastic stretchsole which is lasted entirely about the perimeter edge of and forms an elastic end closure for the shoe upper, said lasted elastic stretchsole being able to deform and rebound repeatedly on-demand in response to the compression forces generated thereon by a person's foot, and
- at least one median cavity housed within the outsole of the footwear article and positioned adjacent to said lasted elastic stretchsole of the shoe upper, said median cavity being capable of receiving at least a part of said deformed elastic stretchsole.
In a constructed article of footwear to be worn by a person which includes at least a shoe upper having a perimeter edge for housing the human foot and an outsole portion joined to the shoe upper which serves as an exterior bottom for the article of footwear, the improvement in foot cushioning comprising:
- a continuous, uniform, planar elastic stretchsole which is lasted entirely about the perimeter edge of and forms an elastic end closure for the upper shoe, said lasted elastic stretchsole being able to deform and rebound repeatedly in response to the compression forces generated thereon by a person's foot;
- and
- at least one preformed cavity chamber of determinable dimensions and configuration housed within the outsole of the footwear article, said performed cavity chamber being positioned adjacent to said lasted elastic stretchsole of the shoe upper and presenting not less than one median cavity able to receive at least a part of a deformed elastic stretchsole.
A foot cushioning system for use in a constructed article of footwear which includes a shoe upper having a perimeter edge for housing the human foot and an outsole which is joined to the shoe upper and serves as an exterior bottom for the article of footwear, said foot cushioning system comprising:
- a continuous elastic stretchsole configured as at least one planar sheet and lasted entirely about the perimeter edge of the shoe upper as an end closure, said lasted elastic stretchsole end closure deforming and then rebounding into planar layer form in response to the compression forces generated thereon by a person's foot;
- and
- at least one median cavity existing within a performed cavity chamber which is housed within the outsole of the footwear article, wherein said median cavity and performed cavity chamber lie adjacent to said lasted stretchsole end closure of the shoe upper, and whereby said median cavity is able to receive a deformed stretchsole end closure and to enable said stretchsole to cushion a person's foot from the effects of compression forces.
A foot cushioning system for use in constructed article of footwear which includes a shoe upper having a perimeter edge for housing the human foot and an outsole which is joined to the shoe upper and serves as an exterior bottom for the article of footwear, said foot cushioning system comprising:
- a continuous, uniform elastic stretchsole configured as at least one planar sheet and lasted entirely about the perimeter edge of the shoe upper as and end closure, said lasted elastic stretchsole end closure deforming and then rebounding into planar layer form in response the compression forces generated thereon by a person's foot by;
- and
- a cushioning midsole disposed under said shoe upper and said elastic stretchsole and at least partially within said outsole, said midsole being capable of deforming and rebounding in sympathy with said elastic stretchsole such that said compression forces are at least partially absorbed by said midsole.
