Athletic shoe with independent supports
View Patent ↗An athletic shoe sole construction having a suspension system designed to resiliently support a foot and deflect downwardly upon foot imposed forces is provided. The athletic shoe includes a plurality of independent supports arrayed about the periphery of the suspension system. The supports, or pillars, may include a ground engaging section and a resilient section intermediate the ground engaging section and the suspension system. The suspension system may include a deflectable grid system, or it may include other resilient deflectable materials. The pillars may be constructed and arranged to deflect independently of an adjacent pillar.
1. An athletic shoe construction having a transversely extending suspension system designed to resiliently support a foot and deflect downwardly upon foot imposed forces, comprising:
a plurality of independent supports arrayed about the periphery of the suspension system and extending downwardly therefrom, said supports including a lower ground engaging section and an upper resilient section intermediate the ground engaging section and the suspension system, said supports collectively providing a flexible resilient support for the suspension system; and
wherein the ground engaging section is spaced apart from the suspension system and positioned below the upper resilient section and is formed of a more rigid material than the resilient section, and wherein each independent support is separate from an adjacent independent support substantially up to the suspension system.
2. The athletic shoe construction of claim 1 , wherein the suspension system is located in a heel portion of the shoe.
3. The athletic shoe construction of claim 1 , wherein the suspension system comprises a deflectable grid.
4. The athletic shoe construction of claim 1 , wherein the suspension system is located in a midsole portion of the shoe.
5. The athletic shoe construction of claim 3 , wherein the deflectable grid is formed into a midsole portion of the shoe.
6. The athletic shoe construction of claim 1 , wherein portions of the resilient section of the independent supports include at least one of, a groove and a protrusion, extending at least partially about the outer surface of the resilient section.
7. An athletic shoe sole construction comprising:
a transversely extending suspension system designed to resiliently support a foot and deflect downwardly upon foot imposed forces;
an independent support structure positioned underneath the suspension system, the support structure including a plurality of ground contacting sections extending about the periphery of a heel portion of the shoe sole, and a plurality of resilient sections positioned directly above the ground contacting sections, wherein the ground contacting sections are spaced apart from the suspension system and are formed of a more rigid material than the resilient sections, and wherein deflection of a first resilient section is independent from the deflection of an adjacent second resilient section, and wherein the height of the independent support structures is greater than the height of the suspension system.
8. The athletic shoe sole construction of claim 7 , further comprising at least one ground contacting section positioned on the lateral side of the sole, at least one ground contacting section positioned on the medial side of the sole, and at least one ground contacting section positioned on the rear part of the heel portion of the sole.
9. The athletic shoe sole construction of claim 7 , wherein the independent support structure is adjacent the suspension system.
10. The athletic shoe sole construction of claim 7 , wherein the suspension system comprises a deflectable grid.
11. The athletic shoe sole construction of claim 10 , wherein the deflectable grid is located in a midsole portion of the shoe.
12. An athletic shoe sole construction having a transversely extending suspension system designed to resiliently support a foot and deflect downwardly upon foot imposed forces, comprising:
a structure supporting the suspension system from below, the structure including a plurality of resiliently compressible pillars arranged around the periphery of a heel portion of the suspension system, and wherein a first pillar is constructed and arranged to deflect independently of an adjacent second pillar, wherein the height of the pillars is greater than the height of the suspension system and wherein the height of the pillars forms a majority of the overall height of the shoe sole; and
wherein the plurality of resiliently compressible pillars include a resilient section and a ground engaging section positioned below the resilient section, wherein the ground engaging section is spaced apart from the suspension system and is formed of a more rigid material than the resilient section.
13. The athletic shoe construction of claim 12 , further comprising at least one lateral side pillar, at least one medial side pillar, and at least one heel pillar.
14. The athletic shoe construction of claim 13 , wherein the heel pillar has a larger ground engaging surface than either of the medial or lateral side pillars.
15. The athletic shoe construction of claim 13 , wherein at least one of the lateral side pillar and the heel pillar includes a groove extending at least partially about the perimeter of the pillar.
16. The athletic shoe construction of claim 13 , wherein at least one medial side pillar includes a protrusion extending at least partially about the perimeter of the pillar.
17. The athletic shoe construction of claim 12 , wherein the suspension system comprises a deflectable grid.
