The present invention relates to the engineering of insole; more specifically insole with two dominant properties of offloading pressure in one particular area, and providing automatically adjustable arch support. The present invention is configured to provide sufficient support and overall pressure distribution for foot regardless of whether the wearer ^' s foot is over-pronated, under-pronated, or neutral. Background Of The Invention

Foot is an essential part of the body that allows us to complete essential activities in our lives such as walking, running, travell ing, etc. Considering its significance, selecting the right insole for one's foot to ensure comfort, absence of physical affliction, and proper support and reinforcement of the arches and other regions of the foot is compulsory.

There are currently a number of footwear insoles being offered in the market; thus far, majority of these inventions or products critically fail to provide adequate support for the foot especially to the arches of foot. Because each person's arches are of particular height, shape, and form, almost all insoles available are either of incorrect or non-adjustable height, shape, and/or form, resulting in the following problems:

1 . When arch support is formed too high for the arch of the wearer's foot, it tends to prod excessively into the arch of the foot of the wearer for each and every step walked, causing pain and discomfort when walking or running.

2. When arch support is formed too low for the arch of the wearer's foot, it is not capable of properly providing sufficient support for the arch of the foot, the wearer then would walk on a rather fiat insole, suffering from foot strains.

In addition to automatically adj ustable arch support, the present invention allows pressure to distribute evenly across all areas of foot through different layers or well-engineered structure of pressure distributing materials. Thus, the insole is configured to support each and every part of the foot.

Hence, the present invention is formulated to address these issues. The present invention comprises flexible, resilient, and spongy materials in arch region and various other force absorption and distribution materials composing in different areas of said insole. Upon being compressed by the weight of the wearer, the force exerted upon the foot will be distributed across the foot, lessening any pain occurring after a long walk; while the flexible, resilient, and spongy materials acting as an arch support will adjust itself according to the shape of each individual ^' s foot. As a result, the arch of the wearer is properly and sufficiently supported without any pains or discomfort.

Summary Of The Invention

Under this section, the concept of the present invention is introduced, aiming to highlight the main features of the present invention and its assembly method. Further detail will be elaborated under detailed description of the invention section. This is for the purpose of raising an example to give a better understanding of the invention, and not intending to define or limit the scope of the invention.

The insole comprises various layers of force absorption and distribution materials as well as arch support material.

Arch support comprises flexible, resilient, and spongy materials in between layers of force absorption and distribution materials to ensure proper support of the arch of the foot and overall comfort while wearing. Arch support will be located in the arch area of the wearer's foot in between different layers of force absorption and distribution materials.

While, shock absorption and distribution materials are of different thickness, shapes, and sizes. They are placed at different areas of the foot based on its main functions and purposes.

Detailed description of the drawing is w ill be described under this section for a comprehensive understanding of the invention and the drawings. Numerations in correspondence with the drawings are referred to in the detailed description of the invention to clearly indicate certain parts and depicting a clearer concept only, and not for confining or limiting the scope of the invention in any way.

Figure. 1 shows components of pressure offloading insole with automatically adjustable arch support. The present invention comprises force distribution material at heel region ( 1 ), flexible, resilient, and spongy material in the mid-foot region (2), wedge (3), flexible, resilient, and spongy arch support (4), force absorption material at heel region (5), force absorption material at forefoot to mid-foot region (6), force distribution material (7), and sock lining (8).

Force distribution material at heel region ( 1 ) and flexible, resilient, and spongy material in the mid-foot region (2) are located at the base layer of the insole (9). A wedge (3) is placed on top of the base layer of the insole using glue or any device capable of attaching them together. Flexible, resilient, and spongy arch support (4) is placed on top of the wedge (3) using glue or any device capable of attaching them together. Force absorption material at heel region (5) and force absorption material at forefoot to mid-foot region (6) are located in the mid-layer of the insole (10). Force distribution material (7) is located under the top layer of the insole ( 1 1 ). Lastly, sock lining (8) is placed on the top of the insole ( 12).

Force distribution material at heel region ( 1 ) assists with supporting and distributing any pressure exerted on the heel region while walking lessening pain occurring from walking.

Flexible, resilient, and spongy material in the mid-foot region (2) assists with filling, shaping and supporting mid-foot area of the wearer. The material makes it possible to adjust to feet of different shapes and forms.

A wedge (3) function is also made of shock distributing material. Its main function is to distribute the weight exerted on the heel region towards mid-foot region to alleviate pressure from one particular spot.

Flexible, resilient, and spongy arch support (4) is generally made of high-density foam. It works as a mold for each wearer's feet. It is located on the arch area of the insole, adjusting itself to different foot shapes and forms. With the help of flexible, resilient, and spongy material in the mid-foot region (2) in the base layer (9), they work together to push up, fill, and ensure maximum support at the arch and the mid-foot area of the wearer.

Force absorption material at heel region (5) works to absorb any shock exerted on the heel region before the force gets distributed in other areas of the foot. Force absorption material at forefoot to mid-foot region (6) works to absorb any shock exerted on the forefoot to mid-foot region. The material used is of different hardness than force absorption material at heel region (5). Generally it tends to be of lesser hardness, making it softer. The forepart of the insole will then provide a softer sensation when walking and sufficient support as the ball of foot is highly susceptible to pain affliction from shock exertion.

Force distribution material (7) is located under the top layer of the insole ( 1 1 ). It works to absorb any immediate shock exerted on the foot before distributing it over to other force offloading materials configured within the insole. Because of the nature of the material, it will also provide footprint effect where each individual's wearer will have their tailored insole after wearing it for some time as this material memorizes the under- foot shape of the wearer.

Finally sock lining (8) is placed on the top of the insole ( 12). It comprises leather, PU, fabric or other material capable of making the finished look of the insole decent and presentable.

All of these components are attached together using glue. lamination or any means capable of attaching them together in the said arrangement.

Side view of pressure offloading insole with automatically adjustable arch support comprises force distribution material at heel region ( 1 ), flexible, resilient, and spongy material in the midfoot region (2), wedge (3), flexible, resilient, and spongy arch support (4), force absorption material at heel region (5), force absorption material at forefoot to mid-foot region (6), force distribution material (7), and sock lining (8).

Commencing from the top, sock lining (8) is attached on top of force distribution material (7) by any means capable of attaching them together. Force distribution material (7) is located on top of two force absorption materials: force absorption material at heel region (5), force absorption material at forefoot to mid-foot region (6). Force distribution material (7), force absorption material at heel region (5). force absorption material at forefoot to mid-foot region (6) are attached to one another by means of glue, lamination, or other devices capable of attaching them together. Force absorption material at heel region (5). force absorption material at forefoot to mid-foot region (6) are also connected via glue, lamination or any means capable of attaching them together. Flexible, resilient, and spongy arch support (4) is attached under force absorption material at forefoot to mid-foot region (6) in the mid-foot region where the arch of the foot is. The wedge (3) is then placed underneath force absorption material at heel region (5) and its other edge will overlap under flexible, resilient, and spongy arch support (4). Force distribution material at heel region ( 1 ) is attached under the wedge in the heel region. Flexible, resilient, and spongy material in the mid-foot region (2) is attached under some part of the wedge (3), next to force distribution material at heel region ( 1 ) and part of it under flexible, resilient, and spongy arch support (4).

All of the attachment required to assembly these component together can be done by using glue, lamination, or any means capable of holding and assembling these components together.
