Abstract: An inflatable bladder for use in an article of footwear including a first sheet of a flexible fluid-impervious material and a second sheet of flexible fluid-impervious material. The first sheet and the second sheet are sealed along air-tight weld lines forming at least one narrow channel. The inflatable bladder includes an air passage device for maintaining air flow within the narrow channel. In one embodiment, the first sheet has an embossed interior surface to limit the contact between the first sheet and second sheet. Another embodiment includes the use of a mechanical device to separate the first sheet and the second sheet within a narrow channel. A method of manufacturing an inflatable bladder, a method of increasing localized air flow though a narrow channel of an inflatable bladder for use in an article of footwear and an article of footwear incorporating the inflatable bladder are also described.

Abstract: A shoe sole is described that provides both cushioning and stability. The sole has a plurality of layers, including a transition layer which allows relative motion between the layers adjacent to the transition layer. The relative motion between the layers of the sole reduces the impact of horizontal shear stresses on the wearer's feet and ankles. One such transition layer includes pliable material and deformable holes within the pliable material. Another transition layer includes at least two rigid plates held together by less rigid grommets or sidewalls. The transition layer may be disposed beneath the entire shoe or only portions of the shoe, with either a more conventional sole structure or rigid support members completing the sole.

The article of footwear also includes a inflation mechanism located under the foot of the wearer to be activated by the normal action of the wearer to inflate the one or more bladders. The inflation mechanism may be monolithic with the bladder or may be a satellite inflation mechanism coupled to the bladder. The article of footwear may also include a deflation mechanism. The deflation mechanism may include a release valve capable of remaining in a open position and/or an adjustable check valve. The deflation mechanism may also be a combination check valve and release valve accessing a single opening in the bladder.

Abstract: A closure system comprises a hook and pile material having hooks on one side and pile on the other side. With regard to footwear, the present invention is a shoe comprising this material allowing a wearer to adjust the point of attachment of closure straps on the exterior of the outer member of the shoe, thereby allowing every shoe wearer to wear the strap across the throat of the shoe at a different location. With regard to apparel, the present invention is a closure system comprising a single-ply hook and pile material in which the overlapped piece, or the exterior piece attaches to the underlapped piece, or the interior piece that provides the wearer with the ability to customize the fitting of the apparel, including the tightness of the apparel around an individual.
