Air Right Insoles
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.

FIELD OF THE INVENTIONThis invention relates to safety footwear and in particular concerns the insoles of safety footwear, useful in a working environment where an individual would spend a considerable amount of time standing or walking without rest.
BACKGROUND OF THE INVENTIONSafety footwear is classified as personal protective equipment, produced in different types and forms (shoes, boots, etc.), according to the intended use thereof, and protects workers' feet from various types of risk such as shocks, collisions, impact, thermal and chemical burns, puncturing and crushing, cuts and abrasions, heat, flames and cold.
Safety footwear is provided with a protective toe-cap, to protect the feet in the event of material falling on the foot, and a puncture-resistant sole, consisting of a steel plate which protects the foot from sharp materials which could penetrate the sole such as nails, sharp-edged blades or other.
Safety footwear is furthermore provided with a non-slip rubber outsole, which also protects against the risk of electrocution, and a heat insulating insole.
All this provides the wearer considerable protection, but very little comfort or support.
Safety footwear, and in particular the soles and insoles thereof, do not have comfort as an integral part of their construction. This causes numerous aches, pains and injuries for individuals that are required to wear safety foot wear for eight hours or more a day as a condition of their employment.
This invention addresses that need for comfort and support in safety footwear, with a uniquely constructed insole pad to be inserted into the footwear.
This insole will consist of Cushioning Material, a flexible closed cell plastic film (bubbled rubber material) layered on top of and adhesively bonded to a rubber semi-rigid base formed with extra support 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 cushioned insole provides substantial enhanced comfort, side to side stability, and massages the foot as the wearer moves or walks.
SUMMARY OF THE INVENTIONTo remedy discomfort, pain, and/or injuries mentioned above, a new type of insertable support insole for safety footwear has been designed.
One object of the new insole is to make production of the insole independent of production of the other parts of the shoe.
A further object of the new insole is to be able to produce different types of shoes with the same insole.
A further object of the new insole is to allow the use thereof, also with shoes of different sizes.
A further object of the new insole is to permit the replacement thereof when damaged, worn or simply no longer hygienic with a new insole offering maximum safety and hygiene.
A further object of the new insole is to provide the foot side to side stability with the inclusion of a winged area on each side of the base of the insole.

Claims
1. A cushioned insole structure for use in a shoe or boot, the cushioned insole comprising:
- a) a foot-shaped base layer made of durable semi-rigid rubber, with arch support and side to side stability wing support.
- b) a foot-shaped top layer made of flexible closed cell plastic film/bubbled rubber material consisting of a composite of 5 or more sheets of polyurethane films or similar plastic that are 5/16″ high by ⅞″ wide. The film shall be fabricated in such a manner that the resulting material will be able to sustain regular wear for a period of at least 30 days without breakage or degradation.
- c) the foot-shaped base layer and foot-shape top layer shall attach and combine both said foot-shaped base layer and foot-shape top layer with the result that they are connected and lined, constituting one single body.
- d) said attaching includes an adhesive bonding means for adhesively attaching the upper surface of said foot-shaped base layer to the lower surface of said of said foot-shaped top layer
2. The insole according to claim 1, wherein said removable and replaceable insole is suitable for insertion in any shoe or boot.
3. The insole according to claim 1, wherein said body comprises one or more rubber materials.
4. The insole according to claim 1, wherein said cushioning elements have an inherent air cushioning characteristic where the air is the primary cushioning agent, and the materials used to form the insole are merely a means to contain the air in such a manner as to provide comfort, support, and massage, not the primary support or cushioning means.
5. The insole according to claim 1, further comprising one or more cut lines indicating where the insole can be cut to accommodate feet of different size.
6. The insole according to claim one wherein said one or more cut lines are on the heel and forefoot sections of the insole.
