Benefits of technology

[0021]This method will also accommodate changes in the athlete's physical situation, which often occur during an athletic event. For example, an injury to the athlete's leg or foot may mandate a different target force threshold; in that instance, a new shoe can be constructed to immediately accommodate this changed physical situation. Muscle fatigue, for example, could warrant constructing another shoe for the second half of the athletic event. Orchard and Powell concluded by analyzing 5,910 NFL games that not only field composition affected injury rates, but also cold weather vs. hot weather, wet vs. dry conditions, and even early season vs. later season conditi

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 unsta

Example

[0056]The athletic shoe 10 according to a first embodiment of 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 rotationa...

Example

[0070]FIG. 15 shows a variation of the second embodiment of the invention with a channel 71 incised into the outer surface of sole 100. Channel 71 is somewhat shallower than channel 72 shown in FIGS. 12-14 and extends for a much greater length with more undulations than channel 72. As in the soles show above, the exact width, depth, geometry and pathway of channel 71 can be varied to provide the exact response desired to provide a mitigating deformation induced by a particular athlete's pre-determined, pre-injury force threshold.

[0071]FIG. 16 shows a plan view of an alternate construction of a force-mitigating sole constructed according to the second embodiment of the invention. It is noted that FIG. 17 is a view taken along the plane E-E of the sole shown in FIG. 16. FIGS. 16 and 17 will be described together. Sole 70′ has 4 separate channels 72″ incised into an outer layer 73 of the sole 70′. It is noted that the channels of the sole of the second embodiment do not have to be cont...

Example

[0077]FIGS. 26-33 show a third embodiment of the invention. In this embodiment the sole is strategically weakened to provide the desired temporary deformation via inserts in the sole rather than by incising a channel in the sole. FIGS. 26 and 27 will be described together with it being understood that elements shown in one figure may or may not be shown in the other figure. It is noted that the inserts are all shown in the forward [toe] portion of the sole. Obviously, one or more inserts could be positioned in the mid portion of the sole, or even in the heel portion of the sole, if desired.

[0078]Sole 110 is a multi-layer composite sole similar in construction to the first and second embodiment soles shown and described above. The forward portion of sole 110 contains 4 inserts, 112, 112′, 114 and 114′. These inserts are made of a composite filler material similar to the sole materials described above; however, the filler material may or may not include bound fibers. The filler materi...

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...
