An insole structure for footwear comprised of upper and lower surfaces which form one or more internal cavities within the body of the structure, the cavities so formed containing a fluid such as water, air or a gel, providing thereby a durable and comfortable means for cushioning and supporting the feet inside footwear such as shoes, sandals, slippers and/or boots. The present invention may find embodiment in (i) a flexible contoured insole designed for insertion into conventional footwear or (...

An improved article of footwear comprising a heelboard and an upper wherein the outer edge of the upper is bent around the heelboard and adhesively bonded to the lower surface thereof, wherein the improvement comprises a sheet of resin which covers at least a portion of the lower surface of the heelboard, said resin being selected from the group consisting of: A. copolymers of at least one olefin with at least one nonhydrocarbon aliphatic monomer, and B. blends of A with at least one polyolefin,...

Footwear, such as a boot or shoe, having an insole comprising an extruded foamed resin sheet wherein the resin is an ethylene-vinyl acetate copolymer or a blend thereof with polyethylene and has a polymerized vinyl acetate content of 2-17 percent by weight. The insole has a substantially uniform thickness, a substantially closed cell structure, and a density of 17-40 pounds per cubic foot. Preferably, the insole is treated with an electric discharge prior to being bonded to the other components ...

A protective insert for a shoe, the insert being contoured to conform to the insole of the shoe and having a sculptured heel portion to cup the heel of the wearer in the space between the counter of the shoe and the insole. The insert is formed by an underlayer of foamed, closed-cell, flexible plastic material of high density, laminated to a face layer of a fabric which is longitudinally stretchable to facilitate sliding of the foot within the shoe.

A cushion type innersole for use with a shoe comprising a first relatively upwardly positioned innersole element conforming generally to the shape of a foot of a wearer, a second innersole element moveably interconnected to and at least partially disposed beneath said first innersole element, the second innersole element being of a generally U-shaped configuration and extending rearwardly from that part of said first innersole element normally underlying the metatarsal area of said foot. Dispose...

Insole of non-woven bonded fiber sheet material including a shank portion of greater stiffness and density than the forward portion in which a through layer of non-woven fiber sheet including a heat-softenable binder is associated with one or more layers of non-woven fiber sheet including binder in the heel and shank or waist portion of the insole and the layers in the heel and shank or waist portion are consolidated by heat and pressure to a unitary board-like state in the heel and shank region...

An insole includes a first layer made of a first slice foam material formed by a foamable polyurethane resin composition. A second layer is made of a second slice foam material formed by bonding together particles of comminuted previously formed foam material with a foamable polyurethane resin composition. The second layer is adhered to an upper surface of the first layer. The second layer has a thickness being greater than that of the first layer.

A latch, particularly for vehicle doors, includes a keeper for mounting on a door frame and provided with a recess. A catch for mounting on a door which is associated with a door frame includes a catch pin receivable in the recess and adapted for rotation about its axis. The catch pin includes an abutment face which cooperates with the keeper upon penetration of the catch pin into the recess to thereby prevent opening of the door.

An apparatus and method of making it is provided whereby a liquid-filled shoe insole is produced. The insole comprises discreet internal liquid-filled ampules which are strategically placed between upper and lower laminae and sealed in place to provide separate support for various parts of the foot.

The present invention teaches a novel, cushioned insole for footwear such as shoes, boots or the like. The insole comprises a multi-layered laminate that has a periphery which conforms generally to the shape of the inside surface of the sole of the footwear so that the insole may be readily placed in and removed from the footwear. The laminate preferably consists of a central, spongy core made of a foamed plastic material which is covered on its upper surface by a thin layer of generally fluid i...
