Abstract

An athletic shoe generally has a plurality of strips of an inextensible material, such as graphite, which extend from the lace area rearwardly over the shoe exterior and into a non-ground contacting area of a laminated sole. The weight of the wearer also bears upon the strip sole ends and aids in retarding movement thereof. The shoe has good forward as well as lateral stability.

Claims

1. An athletic shoe, comprising:

a laminated sole and an upper, said laminated sole comprising at least a midsole and an outersole,

a lace area, said lace area residing on said upper,

one or more flexible inextensible strips, said strip having a lace end and a sole end, said strip residing on said upper, said lace end of said strip attached to said lace area and said sole end of said strip extending into said laminated sole at least 45 percent of the distance from the outer edge of said laminated sole to the center axis of said sole laminate and attached thereto so that lateral and forward stability is imparted to the shoe.

2. An athletic shoe according to claim 1, wherein said inextensible strip lace ends are attached to said upper.

3. An athletic shoe according to claim 1, wherein said lace area has eyelets therein and wherein said inextensible strip engages said eyelet.

4. An athletic shoe according to claim 3, including a plurality of said inextensible strips, said inextensible strips extend rearwardly and downwardly from said lace area to said sole.

5. An athletic shoe according to claim 4, wherein said inextensible strips extend rearwardly at a angle of from about 55 degrees to about 75 degrees.

6. An athletic shoe according to claim 5, wherein said inextensible material is fiberglass, graphite, or polyester, or polyaramide.

7. An athletic shoe according to claim 6, wherein said inextensible strips are attached to the midsole of said shoe.

8. An athletic shoe according to claim 7, wherein said strips are encapsulated to the underside of said midsole, and wherein said encapsulated strips extend entirely across said sole.

9. An athletic shoe according to claim 8, wherein said inextensible strips are made from encapsulated graphite fibers.

10. An athletic shoe according to claim 2, wherein the length of said sole extends along the entire length of said shoe.

11. An athletic shoe according to claim 7, wherein the length of said sole extends along the entire length of said shoe.

12. An athletic shoe according to claim 1, wherein said inextensible strips extend rearwardly and downwardly from said lace area to said sole, and wherein said rearward angle is from about 55 degrees to about 75 degrees.

13. An athletic shoe according to claim 12, wherein said inextensible strips extend entirely across said sole interior.

14. An athletic shoe according to claim 13, wherein said lace area has eyelets or speed laces and wherein said inextensible strips engage said eyelets or said speed laces.

15. An athletic shoe according to claim 14, wherein said inextensible strips are attached to the midsole of said sole, wherein said rearward angle is from about 60 degrees to about 72 degrees, and wherein said inextensible strips extend at least 70% into said sole interior.

16. An athletic shoe according to claim 15, wherein said inextensible strips are laminated to the underside of said midsole.

17. An athletic shoe according to claim 16, wherein said inextensible material is encapsulated graphite.

18. An athletic shoe according to claim 13, wherein said inextensible strips are capable of providing a taut abutment of said upper to a foot and providing a close engagement of said sole with the bottom of said foot, and wherein upon the application of pressure by said foot to said sole, said inextensible strips substantially eliminate movement between said shoe and said foot.

19. An athletic shoe according to claim 16, wherein said inextensible strips are capable of providing a taut abutment of said upper to a foot and providing a close engagement of said sole with the bottom of said foot, and wherein upon the application of pressure by said foot to said sole, said inextensible strips substantially eliminate movement between said show and said foot.

20. An athletic shoe, comprising:

a laminated sole and an upper, said laminated sole having a plurality of layers, one or more flexible inextensible strips, said inextensible strip being incapable of elongation,

a laced area, said lace area residing on said upper, said inextensible strip residing on said upper and extending from said lace area into said laminated sole area an amount of at least 45 percent of the distance from the sole outer edge to the central axis of said sole.

21. An athletic shoe according to claim 20, including a plurality of said inextensible strips, wherein said inextensible strips contain graphite fibers.

22. An athletic shoe according to claim 21, wherein said inextensible strips extend rearwardly and downwardly from said lace area to said sole, and wherein said rearward angle is from about 60 degrees to about 72 degrees.
