Benefits of technology

The present invention relates to an athletic shoe designed to prevent injury to an athlete's lower extremity joints during training or games. The shoe is constructed to induce a mitigating deformation at a predetermined force threshold, which is unique to each athlete based on factors such as mass, speed, and strength. The shoe's sole is made of multiple layers of engineered composite materials that provide rigidity and strength only up to the predetermined force threshold. When the force threshold is reached, the sole deforms to absorb the stress and protect the athlete's joints from injury. The shoe's sole is made of low-density, high-strength materials that instantly return to its original shape after the athlete has progressed through the force-generating movement. The invention allows for a custom-tailored shoe for each athlete, ensuring the best protection against injury.

Problems solved by technology

At some point, the human body is naturally unable to compensate for this force.
Yet few attempts at preventing non-contact ACL injuries have involved a viable athletic-shoe solution.
Results have yielded shoe designs with unstable vertical profiles that compromise athletic performance and increase injury risk.
In spite of these, the incidence of non-contact ACL injuries continues to rise—painful proof that a practical solution has yet to be realized.

first embodiment

[0056]The athletic shoe 10 according to the invention is shown in FIGS. 1-8. The athletic shoe soles shown in FIGS. 1-8 are designed to protect an athlete's lower extremities against both injurious torsional [i.e., torque] forces and injurious longitudinal forces.

[0057]The shoe sole shown in FIGS. 1-8 comprises an upper body 12 and a multi-layer composite sole 14. Multi-layer composite sole 14 is shown in FIGS. 2-8 as comprising 5 thin layers of materials, although the exact number of layers could be more or less than 5 depending upon the specific situation the shoe is designed for. As shown in FIG. 3, sole 14 comprises layers 20, 21, 22, 23 and 24. Layers 20, and 24 are designed to provide rigid translational [i.e., straight ahead] stability during competition, like a traditional athletic shoe, only up to a pre-determined, athlete-specific, target pre-injury force threshold. These layers will also contribute limited rigidity during lateral as well as rotational [i.e., twisting] for...

second embodiment

[0066]FIGS. 12-14 show a force-mitigating athletic shoe sole constructed according to the invention. The three figures will be described together with it being understood that elements shown in one figure may or may not be shown in the other figures.

[0067]Sole 70 is a multi-layer composite force-mitigating sole similar in construction to the first embodiment soles shown and described above. Multi-layer composite sole 70 is shown as comprising composite layers 73, 74, and 75, although the exact number of layers could be more or less, as desired. Sole 70 comprises materials similar to those of the first embodiment. Multi-layer sole 70 has a cut-out or channel 72 incised into the outer surface of layer 73. Channel 72 is shown in the figures as being incised into the forward portion of sole 70. It should be understood that the exact placement of channel 72 can and will vary depending upon the desired force-resisting characteristics of sole 70 just as the width, depth and exact pathway o...

third embodiment

[0076]FIG. 24 is a plan view of yet another alternate version of a force-mitigating sole constructed utilizing portions of all three embodiments of the invention. It is noted that FIG. 25 is a view taken along the plane I-I of the sole shown in FIG. 24. FIGS. 24 and 25 will be described together. In the invention, the force-mitigating sole is strategically weakened to provide the desired temporary deformation by providing inserts in the sole rather than by providing a channel incised into the sole. However, there is no reason why a force-mitigating sole cannot be constructed using multiple embodiments of the invention in the same force-mitigating sole. Indeed, a force-mitigating sole may be constructed using all of the embodiments of the invention. This is illustrated in FIGS. 24 and 25. Force-mitigating sole 92 comprises three layers 97, 98 and 99. Sole 92 has cut-outs 93, 93′, 94 and 94′ incised into inner layer 98, although the cut-outs could be in layer 99 or layer 97, if desire...

Abstract

An athlete in any athletic event generates forces on and subjects their lower extremities to forces which are unique to that athlete's mass, speed and strength. These forces are also affected by the composition of the playing field surface, shoe design and construction and other factors. It is possible to determine, according to these factors, the level of force above which injury to the athlete's lower extremities is inevitable—the pre-injury force threshold. This pre-injury force threshold is then used to design and build an athletic shoe which will provide a force-mitigating deformation induced by forces equal to the particular athlete's pre-injury force threshold. This deformation of the athletic shoe prevents injury to the athlete's lower extremities. This deformation may be induced by designing the sole of an athletic shoe with specifically engineered incised cut-outs or channels in the athletic shoe sole.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 15 / 145,774 filed on 3 May 2016, [now U.S. Pat. No. 10,383,395]. This application claims the benefit of U.S. 62 / 156,276 filed on 3 May 2015. This application incorporates by reference U.S. patent application Ser. No. 15 / 145,774 filed on 3 May 2016, [now U.S. Pat. No. 10,383,395] and 62 / 156,276 filed on 3 May 2015.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableSEQUENCE LISTING[0003]Not ApplicableBACKGROUND OF THE INVENTION[0004]Each year in North America there are approximately 250,000 ACL injuries—about 70% of which are non-contact incidents.1 A near universally accepted and scientifically supported explanation for this non-contact statistic is the rotational and translational forces created when a player makes a sudden change in direction or stops. Exacerbating this natural force generation is athletic-shoe / playing-surface in...
