Abstract

An athletic shoe is described with an outer sole having a laterally elongated matetarsal cleat of resilient material molded integral with such outer sole. The metatarsal cleat extends laterally across the entire width of the toe portion of the sole in a position immediately behind the heads of the metatarsal bones of the wearer'"'"'s foot. In one embodiment the metatarsal cleat is in the form of a curved chevron including two wing shaped side portions each having curved front and rear surfaces to provide good longitudinal traction and self-cleaning action under wet condition. In additon, the chevron cleat is provided with two end portions and an intermediate porton having straight edges extending longitudinally to provide greater lateral traction. A plurality of other cleats of different shape and smaller ground engaging surface area than the metatarsal cleat are also molded integral with the outer sole. These other cleats are of a straight sided polygon shape, such as a hexagon or square, and are of the same height as the metatarsal cleat. The athletic shoe is for use in sports such as soccer, football or baseball, requiring quick lateral movement as well as longitudinal movement, on natural grass turf or synthetic plastic turf.

Claims

1. An athletic shoe in which the improvement comprises:

an outer sole having a plurality of spaced cleats of resilient material molded integral with said outer sole under the toe and heel portions of the shoe;

said cleats including an elongated lateral cleat extending laterally across substantially the entire width of the toe portion of said sole;

said cleats each having a substantially flat ground engaging bottom surface and including a plurality of other toe cleats of smaller ground engaging surface area than said lateral cleat, said other toe cleats being positioned in front of said lateral cleat, substantially the same height as said lateral cleat, and spaced from each other laterally across the width of said sole.

2. A shoe in accordance with claim 1 in which the lateral cleat is a metatarsal cleat which extends laterally behind the heads of the metatarsal bones of the wearer'"'"'s foot and includes a curved intermediate portion between the opposite ends of said lateral cleat.

3. A shoe in accordance with claim 2 in which the lateral cleat is of a curved chevron shape including two side portions on opposite sides of the longitudinal axis of the sole, said side portions have rearwardly curved front and rear surfaces.

4. A shoe in accordance with claim 3 in which the chevron cleat also includes end portions at the ends of said side portions, said end portions having straight edges at least some of which extend longitudinally of the sole.

5. A shoe in accordance with claim 4 in which the chevron cleat includes an intermediate portion at the junction between the two side portions, which includes additional straight longitudinal edges.

6. A shoe in accordance with claim 2 in which the lateral cleat is of a generally crescent shape with a concave curved front surface and a convex curved rear surface.

7. A shoe in accordance with claim 6 in which one end of the lateral cleat adjacent the inside edge of the outer sole is positioned ahead of the opposite end of the lateral cleat adjacent the outside edge of said outer sole.

8. A shoe in accordance with claim 6 in which the other toe cleats include triangular toe cleats and V-shaped toe cleats positioned ahead of the lateral cleat and each being of smaller ground engaging surface area than said lateral cleat.

9. A shoe in accordance with claim 1 in which the other toe cleats are of different shape than said lateral cleat but are of substantially the same height and all of said cleats having a substantially rectangular cross section taken perpendicular to the bottom surface of said outer sole.

10. A shoe in accordance with claim 9 in which said other cleats have bottom surfaces which are straight sided polygons.

11. A shoe in accordance with claim 9 in which said other cleats have hexagonal bottom surfaces.

12. A shoe in accordance with claim 1 in which an intermediate sole layer of greater thickness, less hardness and lower density than said outer sole is provided between the shoe upper and said outer sole.

13. A shoe in accordance with claim 1 in which the heel portion of the outer sole is provided with heel cleats of different shape than said lateral cleat but of substantially the same height.

14. A shoe in accordance with claim 13 in which the heel cleats are straight sided polygons.

15. A shoe in accordance with claim 14 in which the heel cleats include an elongated heel cleat extending laterally across the heel portion adjacent the rear of the sole and a plurality of smaller heel cleats of less cross sectional area than said elongated heel cleat positioned in front of it.

16. A shoe in accordance with claim 2 in which the lateral cleat has a convex curved front surface and a concave curved rear surface.

17. A shoe in accordance with claim 16 in which one end of the lateral cleat adjacent the inside edge of the outer sole extends substantially straight laterally and is positioned ahead of the opposite end of said lateral cleat adjacent the outside edge of said outer sole.
