Abstract: A custom conformable device that supports and cushions a user's anatomical part, such the foot. The device is self-inflating, conforms to the shape of the user's foot, utilizes an inflatable bladder with a valve, and contains an expandable material such as an open cell foam. When the valve is open the expandable material expands, causing the bladder to inflate and to conform to the shape of the user's anatomical part. Once the desired shape is achieved, the valve is closed, sealing the bladder. Once the bladder is sealed, the expandable material retains the shape of the user's anatomical part. The user may open the valve to adjust the level of support provided by the device by allowing more fluid to enter the bladder, or by forcing fluid to exit the bladder.

Abstract: The present invention comprises a multilayered heel construction for footwear. A fluid-filled bladder is incorporated into the heel of footwear. The bladder defines an internal cavity which is adapted to enclose a fluid at atmospheric pressure. The internal cavity defines a peripheral channel adjacent the periphery of the bladder and a plurality of intersecting channels orientated transversely to the longitudinal axis of the footwear. The intersecting channels are in communication with the peripheral channel of the interior cavity. The bladder is positioned at the heel of the footwear and is positioned intermediate an upper footbed support. The lower surface of the multilayered heel assembly defines a concave, cantilever surface. The combination of the bladder, the upper footbed support and the lower cantilever surface improve shock absorption and the stability of the footwear.

Abstract: The present invention relates to a sole for an article of footwear and the method of manufacture. The sole includes a mesh layer at least partially embedded in a sole layer. The method for manufacturing the sole includes the steps of providing a mold, inserting a mesh into the mold, and forming a sole layer in the mold, the sole layer having a mesh layer at least partially embedded in the sole layer. The invention also relates to an article of footwear that includes this sole, and the method of manufacture thereof.

Abstract: An orthotic insert having an angled lateral surface that engages the insole so as to pivot the insert in a lateral direction and invert the rearfoot at heel strike, and a medial bottom surface that freely interfits within the heel counter and insole of the shoe so as to avoid limiting pivoting motion in the medial direction as the weight on the foot shifts forwardly and medially. Pivoting motion in the medial direction is arrested by engagement between a distal medial portion of the rigid plate member and the insole along the transverse plane of the shoe. The distal medial portion of the plate member is located generally proximal and beneath the first metatarsal head of the foot. The upwardly angled medial surface of the post permits the post to fit optimally within the heel area of the shoe and also avoids interference between the heel counter/insole and the post that would impair proper operation of the insert.

Abstract: A rail cover may be snapped on or off the side of Picatinny rail mounted to a weapon, such as a rifle. The rail cover protects the user from the teeth of the rail and from heat generated during repeated firing. The rail cover is readily installed or removed from the side, rather than being slipped over the end of the rail, by pressing it onto the rail or by prying it off the rail. The slightly flexible rail cover is preferably made of a polymer to which a rubberizing agent has been added and by forming grooves in its top surface. In addition to improving flexibility, the grooves also improve the user's grip on the rail cover. Locking tabs on the underside of the rail cover, dimensioned to fit in the grooves between adjacent teeth of the Picatinny rail, prevent axial movement of the rail cover when it is installed.
