Abstract: A layered construction for a footwear insole connect an intermediate layer between a bottom layer and a top layer. A sealed passage for airflow is created between a plurality of three-dimensional pockets (connected on the top layer), a plurality of apertures (traversing through the intermediate layer), and a reservoir (positioned interior to the bottom layer). The three-dimensional pockets are deformable beneath the weight of a person's foot, which causes air to flow through conduits of the top layer, the apertures of the intermediate layer, and into the reservoir. When a person lifts their foot the three-dimensional pockets return to their normal shape, with air circulating back into the three-dimensional pockets from the reservoirs. The bottom layer can also be contoured to provide better support for a person's foot, matching a concave portion with the foot's longitudinal arches and a pair of wings with the transverse arch.

Abstract: An insole structure is disclosed. The insole is comprised of a cushioned flexible closed cell plastic film (bubbled rubber material) layered on top of and adhesively bonded to a rubber semi-rigid base formed with wings along the side for extra support and stability along the sides of the foot and in the arch area. The combination distributes the pressure created by the foot evenly between the bubbles, so each component absorbs a portion of the pressure, and the combination remains soft and comfortable under the wearer's foot even when the footwear is worn for extended periods of time. This new type of cushion insole provides substantial enhanced comfort, side to side stability, and massages the foot as the wearer moves or walks.
