Walking

F ield of the invention

The present invention relates to a footwear. More particularly, the present invention relates to a sole of a footwear for reducing accidental crushing of insects when a user is walking.

Background of the invention:

Large number of small insects move on the ground. These small insects are important part of a Food-chain. These small insects also play very important role in decomposition of natural wastes, dead animals and garbage. These insects aerate and mix the soil and are conducive to mineralization of nutrients and their uptake by vegetation.

While human beings are walking on the ground surface wearing a footwear, accidentally these small insects and other organisms are killed by contact of a sole of the footwear and the ground.

T hese i nsects and organi sm are reduced drasti cal ly i n number. T he i ncrease of death rate of insects is due to many reasons primarily use of heavy instruments and equi pments I i ke tractors and harvesters i n farmi ng, i ncreased touri sm by vehi cl es i n villages and biodiversity hotspots, human activities in natural habitats. Accidental killi ng of insects by contact of footwear with the ground when a user walks is also contri buti ng for i ncrease of death rate of i nsects. If the ki 11 i ng of i nsects by footwear is reduced, there will be decrease in the death rate of insects. A lso, this accidental killi ng of insects by the user is considered as grievous amongst some communities of the world.

T herefore, there is a need of a sole for reduci ng the accidental ki 11 i ng of the i nsects by crushing between the sole of the footwear and the ground while human beings are wal ki ng by weari ng the footwear.

An embodiment of this invention, illustrating its features, will now be described in detail. The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive I isti ng of such item or items, or meant to be I i mited to only the I isted item or items.

T he terms ^" f i rst, _ ^' second, _ and the I i ke, herei n do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and the terms ^' a_ and ^' an_ herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item.

The present invention is to provide a sole of a footwear with reduced contact area with ground, thereby reducing accidental crushing of insects and other organisms when a user walking by wearing the footwear. Further the sole of the footwear is easy to manufacture.

Reffering now to Figure 1 , the figure 1 shows a sectional view of a sole 300 of an ordinarily existing footwear (not shown). The sole 300 includes a contacting surface 310 for contacting with the ground 50. The contacting surface 310 is in compl ete contact with the ground 50. If a user wal ki ng on the ground 50 by weari ng the ordinarily existing footwear steps on insects accidentally or unknowingly; the insects get killed by crushing contact between the contacting surface 310 and the ground 50. The surface area of the contacting surface 310 is more. So, the chances of crushing insects are also more. The probability of escape of insects from crushing is very less or almost impossible.

Referring now to figure 2 , the figure 2 shows a sectional view of a sole 100 of a footwear 1000 .The sole 100 is the lower portion of the footwear 1000 for contacting with the ground 50. The sole 100 can be made up of rubber, leather or any other material which is obvious to person skilled in the art which is used as a material for manufacturing of the sole 100 of the footwear 1000. A plurality of cavities 60 is engraved in the sole 100 to configure a contacting surface 80 with a border 10 (reffer figure 3) .. The border 10 is provided for providing stability to the user. It may be obvious to provide a sole 100 without the border 10. The contacting surface 80 and the border 10 are in contact with the ground 50.The contacti ng surface 80 and the border 10 forms an outer surface of the sol e 100. E ach of the plurality of cavities 60 includes an inner surface 40. The depth of each of the plurality of cavities 60 is adequate enough to prevent the contact between the ground 50 and the inner surface 40.The depth of each the plurarity of cavities is in the range of 4 to 8 mi I i meter. The surface area of inner surface 40 and the total surface area of the contacting surface 80 along with the border 10 are in the range of ratios between 6:4 and 8:2. If the user walking on the ground 50 by wearing the footwear 1000 steps on insects accidentally or unknowingly; the insects get killed only if the insects falls in the contacting area of the contacting surface 80 along with border 10 and the ground 50 by crushing. The surface contact area of the contacting surface 80 and the border 10 is 60-80 percent less than the contact area of the ordinary footwear; therefore, probability of saving of insects is by 60-80 percent more as compared to the ordinary footwears. The chances of crushing insects is less with the footwear 1000 as compared to the ordinary footwear as the probability of escape of insects from crushing is also more.

Referring now to figure 3 which shows a bottom view of a pair 2000 of the footwear 1000 havi ng the sol e 100. T he footwear 1000 i ncl udes the sol e 100. T he contacting surface 80 is in surface contact with the ground 50 and the border 10 provides structural stability to the footwear 1000. Each of the plurality of cavities 60 is in rectangular in shape or any other shape. Figure 4 shows isometric view of the sol e 100 of the footwear 1000.

Figure 5 shows another alternative embodiment of the footwear 1000 with the sole 100. The plurality of cavities 60 is triangular, rectangular and irregular in shape. The shapes and pattern of the plurality of cavities 60 of the sole 100 is not limited to the illustrated embodiments. The shapes and pattern can be with various permutations and combinations to reduce contact area with ground, which is obvious to person skilled in art. The construction of the sole should satisfy the condition that the range of ratios of surface area of the inner surface and contact area of the contact! ng surface al ong with the border shoul d be between 8:2 and 6:4. The disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms.

In an alternative embodiment (not shown), the sole of the footwear includes a border. T he border is configured along a peri phery of the sole. T he border is a I i ni ng extending from a periphery of the sole towards ground surface. The plurality of caviti es is engraved i n the sol e i nsi de the border. T he pi urality of caviti es is i n shape of circle, rectangle, triangle or any other irregular shape. The height of the border is adequate in order to avoid contact between an inner surface of the plurality of cavities and the ground.

The sole 100 of the footwear 1000 has an advantage reducing contact area with the ground by 60 to 80 percent, thereby reducing accidental crushing of insects when a user wal ki ng by weari ng the footwear i s reduced by 60 to 80 percent. F urther, the sole 100 of the footwear 1000 is easy to manufacture. Furthermore, the sole 100 of footwear 1000 is economical to afford. T herefore, the sole 100 of the footwear 1000 decreases the death rate of the insects by reducing accidental killing of the insects, thereby indirectly contributing for stability of the food chain. The sole 100 of the footwear 1000 provi des a sati sfactory sol uti on to the some communi ti es of the worl d who is considering accidental killing of the insects while walking as grievous.
