Abstract
Abstract The invention provides a device for covering on a tennis shoe the worn area resulting from dragging the rear foot when hitting the ball and moving into the play, the device comprising a side wall having a curve generally conforming to the side and front of the shoe adjacent the big toe of the wearer and an integral bottom member that extends under the worn part of the sole, the device being fabricated from a tough material more flexible than the shoe whereby in conjunction with the shape of the device it will conform more easily to various different sizes of shoes having the worn area in various locations mainly beneath and forward of the big toe.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
210 words
A device for covering a worn area on a shoe comprising an opened topped member of flexible material having a side wall and a bottom member lying in a plane generally at right angles to said side wall, said side wall having an upper edge and extending from a first region of the shoe intended to lie under the ball of the foot of the foot of the wearer and terminating at a second region adjacent the longitudinal center of the front of the shoe, said side wall having a generally straight section along the side of the shoe and a section of increasing curvature adjacent the intended location of the big toe of the wearer whereby the curvature of said side wall conforms to the side of the shoe between said first and second regions, said bottom member having an outer edge extending between said ends of said side wall, and said device having a region of maximum thickness in the region of said device intended to lie both under the big toe and forward of the big toe of the wearer of the shoe, said device tapering from said maximum thickness to a lesser thickness at said upper edge, said first and second regions and said outer edge.
Claim 2
Independent Claim
210 words
A device for covering a worn area on a shoe comprising an opened topped member of flexible material having a side wall and a bottom member lying in a plane generally at right angles to said side wall, said side wall having an upper edge and extending from a first region of the shoe intended to lie under the ball of the foot of the foot of the wearer and terminating at a second region adjacent the longitudinal center of the front of the shoe, said side wall having a generally straight section along the side of the shoe and a section of increasing curvature adjacent the intended location of the big toe of the wearer whereby the curvature of said side wall conforms to the side of the shoe between said first and second regions, said bottom member having an outer edge extending between said ends of said side wall, and said device having a region of maximum thickness in the region of said device intended to lie both under the big toe and forward of the big toe of the wearer of the shoe, said device tapering from said maximum thickness to a lesser thickness at said upper edge, said first and second regions and said outer edge.
Claim 3
Dependent Claim
73 words
A device for covering a worn area on a shoe according to claim 1 wherein a part of said region of maximum thickness lies in line between the intended location of the big toe of the wearer of the shoe and the surface supporting the shoe, said bottom wall tapering from said region of maximum thickness to a region of minimum thickness along said outer edge of said bottom member of said device.
Claim 4
Dependent Claim
41 words
