Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIGS. 1 to 5 thereof, a new and improved shoe construction embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
More specifically, the shoe construction 10 of the instant invention essentially comprises an organization including a shoe upper 11 formed of a fabric polymeric mesh, such as nylon and the like. The shoe upper includes a shoe upper ankle portion 13 fixedly and coextensively mounted to the shoe upper 11 and formed of an elastomeric webbing defining an entrance opening 13. The upper terminal end of the shoe upper ankle portion 12 is defined as upper terminal end 12a. A respective right and left reinforcing strip 14 and 15 are arranged in parallel relationship extending from the upper terminal end 12a downwardly along the shoe upper 11 mounting a series of eyelet openings within each reinforcing strip for receiving lacing and the like. A toe or nose end of the shoe upper 11 includes a matrix of ventilation ajpertures 16 directed therethrough, and a rear vertical upper portion 19 extends at a rear terminal end of the shoe at a remote end from the toe portion extending upwardly from the sole 18 to the upper terminal end 12a and is of a generally semi-cylindrical configuration extending from the right terminal end 19a to the left terminal end 19b along a minor access of the entrance opening 13 formed of an elliptical configuration. Reinforcing cords 17 are directed from the sole 18 to the reinforcing strips 14 and 15 along the shoe upper 11 and to the shoe upper ankle portion 12.
The sole 18 is formed with an outer row of pneumatic tubes 20 defining a bottom surface of a sole 18, wherein the tubes 20 are arranged in a parallel contiguous relationship relative to one another extending orthogonally relative to a longitudinal axis of the shoe connstruction 10. A first resilient polymeric layer 21 defined by a first durometer hardness is positioned interiorly of the outer row of pneumatic tubes 20. An inner row of pneumatic tubes 22 is laminated to an interior surface of the first resilient polymeric layer 21, wherein the first and second rows of pneumatic tubes 20 and 22 are each defined by parallel rows of pneumatic tubes, wherein a central inner row chamber 23 is positioned medially of the sole 18 within the inner row of pneumatic tubes, wherein the inner and outer rows of pneumatic tubes also extend throughout the rear vertical upper portion 19. The sole 18 further includes a second plymeric layer 24 laminated to an interior surface of the inner row of pneumatic tubes 22 defined by a second durometer hardness less than the first durameter hardness and third polymeric layer 25 laminated to the second polymeric layer 24 defined by a third durameter of hardness less than the first durameter of hardness to provide increasing levels of cushioning to an individual's foot while maintaining stability to the foot within the shoe construction. Further, a fluid absorbent fabric liner 26 is mounted coextensively throughout an interior surface of the shoe for absorbing fluid, such as perspiration. FIG. 4 illustrates that the outer row of pneumatic tubes 20 further include forward and rear tubes 27 and 28 defined as a matrix of tubes orthogonally oriented relative to the outer row of pneumatic tubes 20 and completely contained within the outer row of pneumatic tubes 20 to define a traction enhancing pattern in use of the shoe. Further it should be noted that each of the inner and outer rows of pneumatic tubes are totally enclosed and utilize any gaseous medium therewithin to provide cushioning of and individual's foot during use.
It should be further noted that the organization may further utilized the third polymeric layer 25 to be impregnated with a charcoal material to provide odor and moisture absorbing characteristics for enhanced comfort in use of the shoe construction.
As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant ivention shall be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
