Abstract
Abstract An improved sole for an athletic shoe comprises artificial turf material such as is commercially available and having a flexible backing from which the artificial turf projects in a common direction. Preferably, the turf is cut into the shape of the sole of a shoe in three sections and is adhered to an inner sole of the shoe by an adhesive so as to form a sole of substantially continuous artificial turf material. The sole is of suitable configuration for use with desired types of athletic shoes and may include baseball, soccer, football, tennis, and the like type of athletic shoes. The shoe is of substantially reduced weight relative to conventional such shoes yet affords greatly improved gripping, whether on natural or artificial turf, with avoidance of ankle and spiking injuries typically encountered with athletic shoes employing spikes and the like.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
In an athletic shoe having uppers and an inner sole to which said uppers are joined, an improved traction sole for use on playing fields selectively of natural turf and artificial turf, each said turf defining a surface of said playing field comprising upwardly protruding, randomly oriented, fiber-like elements, comprising: synthetic turf material of a configuration corresponding to a desired traction sole configuration and having a flexible backing layer and plural resilient fiber-like elements extending substantially individually from one surface of said backing layer in random orientations and of a sufficient length to project individually into and interengage with the randomly oriented fiber-like elements of said turf of said playing field surface for providing improved traction therewith in all directions of movement of the sole on the said playing field turf surface, and a layer of adhesive material intermediate said synthetic turf traction sole and said inner sole for securing the traction sole to said inner sole.
Claim 2
Dependent Claim
157 words
In an athletic shoe having uppers and an inner sole to which said uppers are joined, an improved traction sole for use on playing fields selectively of natural turf and artificial turf, each said turf defining a surface of said playing field comprising upwardly protruding, randomly oriented, fiber-like elements, comprising: synthetic turf material of a configuration corresponding to a desired traction sole configuration and having a flexible backing layer and plural resilient fiber-like elements extending substantially individually from one surface of said backing layer in random orientations and of a sufficient length to project individually into and interengage with the randomly oriented fiber-like elements of said turf of said playing field surface for providing improved traction therewith in all directions of movement of the sole on the said playing field turf surface, and a layer of adhesive material intermediate said synthetic turf traction sole and said inner sole for securing the traction sole to said inner sole.
Claim 3
Dependent Claim
41 words
The improved traction sole as recited in claim 1 wherein said synthetic turf material comprising said traction sole is provided in a plurality of individual pieces and secured to said inner sole, thereby to afford improved flexibility of the traction sole.
Claim 4
Dependent Claim
46 words
An improved traction sole as recited in claim 1 wherein said synthetic turf material is formed in plural sections including at least one section corresponding to the heel of the shoe and a further section extending from about the ball to the toe of the shoe.
Claim 5
Dependent Claim
36 words
An improved traction sole as recited in claim 3 wherein said heel section and said further section are formed of a more dense turf material than the turf material forming the remainder of the traction sole.
Claim 6
Dependent Claim
32 words
An improved traction sole as recited in claim 1 further including stitching extending at least about the periphery of the traction and inner soles to secure said traction and inner soles together.
Claim 7
Dependent Claim
33 words
An improved sole as recited in claim 1 wherein there is further provided a strip of edging material overlying the juncture of the inner and traction soles and extending about the periphery thereof.
Claim 8
Dependent Claim
33 words
An improved traction sole as recited in claim 1 wherein said synthetic turf material is trimmed at an angle from the perpendicular to the inner sole about the periphery of the traction sole.
