Abstract

An athletic shoe suitable for use on artificial turf is described including an improved upper of a porous multiple layer construction and an improved sole having integral polygon shaped studs. The upper is preferably made of nylon tricot fabric outer layer, a polyurethane foam middle layer, and a porous synthetic fabric inner layer. This greatly reduces the weight of a football shoe made in accordance with the invention so that it is approximately one-half the weight of a conventional leather football shoe as well as providing great comfort and enabling use in wet weather without damage. The sole has short multi-sided polygon shaped studs of square, rectangular or triangle cross section, having a plurality of flat sides which provide gripping edges that give greatly improved traction.

Claims

2. A shoe in accordance with claim 1 in which the studs are square shaped in cross section.

3. A shoe in accordance with claim 2 in which the studs provided in staggered rows and adjacent studs in each row are spaced apart by a distance at least as great as the width of the studs.

4. A shoe in accordance with claim 1 in which the studs are all of the same size and shape, and are uniformly distributed over the entire bottom of the shoe.

5. A shoe in accordance with claim 1 in which a shoe upper portion of multiple layer construction including an outer layer of porous synthetic fabric, an intermediate layer of foamed plastic, and an inner layer of porous synthetic fabric.

6. A shoe made in accordance with claim 5 in which the outer layer is made of nylon tricot fabric.

7. An athletic shoe in which the improvement comprises:

a shoe upper portion of multiple layer construction including an outer layer of porous nylon fabric, an intermediate layer of porous resilient foam material through which air can pass, and an inner layer of porous synthetic fabric; and

a sole attached to said shoe upper and including a plurality of polygon shaped studs projecting downward from the bottom surface of said sole.

8. A shoe in accordance with claim 7 in which the intermediate layer is made of polyurethane foam and the inner layer is made of nylon fabric.

9. A shoe in accordance with claim 7 in which the sole includes an outer sole layer of resilient material having a plurality of square shaped studs formed integral with and projecting downward from the remainder of said outer sole layer.

10. A shoe in accordance with claim 9 in which the sole includes an intermediate sole layer of resilient material different from that of said outer sole layer and of a greater thickness than said outer sole layer, said intermediate sole layer being provided between the shoe upper and the outer sole layer, and said outer sole layer being of greater hardness than said intermediate sole layer.

11. A football shoe in which the improvement comprises:

a shoe upper;

a sole including an outer sole layer of resilient material having a plurality of studs formed integral with the bottom surface of said outer sole layer and projecting downward from a support portion, said studs being of a multi-sided polygon shape, and an intermediate sole layer of resilient material of lower hardness than said outer sole layer provided between said shoe upper and said outer sole layer, and said studs being adapted to grip artificial turf with high traction.

12. A football shoe in accordance with claim 11 in which the studs are square shaped in cross section and are uniformly distributed over the bottom of the shoe.

13. An athletic shoe in which the improvement comprises:

a shoe upper;

a sole attached to said shoe upper, including an outer sole layer of resilient material having a plurality of multi-sided polygon-shaped studs formed integral with and projecting downward from the remainder of said outer sole layer; and

an intermediate sole layer of resilient material different from that of said outer sole layer provided between said shoe upper and said outer sole layer, said outer sole layer being of greater hardness than said intermediate sole layer and being of less thickness than said intermediate sole layer at least for those portions of the outer sole layer between said studs.

14. An athletic shoe in which the improvement comprises:

a shoe upper portion of multiple layer construction including an outer layer of porous synthetic fabric, an inner layer of porous synthetic fabric and an intermediate layer of porouse resilient foam material through which air can pass between said inner and outer layers; and

a sole attached to said shoe upper including an outer sole layer of resilient material having a plurality of studs formed integral with and projecting downward from the remainder of said outer sole layer, and an intermediate sole layer of resilient material different from that of said outer sole layer provided between said shoe upper and said outer sole layer, said outer sole layer being of a greater hardness than said intermediate sole layer.
