Abstract
Abstract A sole and heel construction such as used on overshoes, boots or shoes having a resilient planar body with a plurality of spaced thin fins that extend transversely across the body. The fins are evenly spaced and uniform in width throughout. All fins are identical and are inclined relative to a horizontal plane such that any weight applied to the sole compresses the fins to trap air between adjacent fins to minimize mud build-up.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
In a ground contacting element which covers substantially the entire bottom surface of a boot, overshoe, shoe or the like, a resilient body adapted to fixedly be secured to the base of an overshoe, said resilient body having a sole portion and a heel portion, said heel and sole portions having a plurality of transversely extending flexible fins, said heel portion being at the rear of said overshoe and said toe portion being at the forward of said overshoe, said fins on said heel portion comprising a first group extending downwardly and rearwardly from said resilient body, said fins on said sole portion comprising a second group extending downwardly and forwardly from said resilient body, the respective fins of said first group have respective front and rear surface portions that are parallel to each other and parallel to adjacent faces of adjacent fins in said first group, the respective fins of said second group have respective front and rear surface portions that are parallel, all of said fins being longitudinally extending, linearly straight and of uniform width for the entire length and height thereof, and said fins of each group being cooperative with adjacent fins in their said respective groups defining grooves therebetween.
Claim 2
Dependent Claim
203 words
In a ground contacting element which covers substantially the entire bottom surface of a boot, overshoe, shoe or the like, a resilient body adapted to fixedly be secured to the base of an overshoe, said resilient body having a sole portion and a heel portion, said heel and sole portions having a plurality of transversely extending flexible fins, said heel portion being at the rear of said overshoe and said toe portion being at the forward of said overshoe, said fins on said heel portion comprising a first group extending downwardly and rearwardly from said resilient body, said fins on said sole portion comprising a second group extending downwardly and forwardly from said resilient body, the respective fins of said first group have respective front and rear surface portions that are parallel to each other and parallel to adjacent faces of adjacent fins in said first group, the respective fins of said second group have respective front and rear surface portions that are parallel, all of said fins being longitudinally extending, linearly straight and of uniform width for the entire length and height thereof, and said fins of each group being cooperative with adjacent fins in their said respective groups defining grooves therebetween.
Claim 3
Dependent Claim
37 words
In a ground contacting element as set forth in claim 1 wherein each of said grooves are of uniform width for the entire length thereof, and each groove width is equal to the width of said fins.
Claim 4
Dependent Claim
34 words
In a ground contacting element as set forth in claim 2 wherein said width of all of said fins is in the range of 0.016 of an inch to a 0.25 of an inch.
Claim 5
Dependent Claim
177 words
A ground contacting element for covering substantially the entire bottom surface of a shoe or the like comprising a resilient body adapted to be secured to the base of a shoe, said resilient body having a forward portion and a rearwardly disposed portion, one of said portions having a plurality of straight transversely extending flexible thin fins, said fins of said one portion having front and rear surfaces that are parallel to each other and parallel to adjacent faces of adjacent fins, the other of said portions having a plurality of straight transversely extending flexible thin fins, said fins of said other portion having front and rear surfaces that are parallel to each other, and the extension of planes containing said faces of said fins of said one portion intersect the extension of the planes containing said faces of said fins of said other portion, all of said fins being of substantially uniform thickness throughout the length thereof, and said fins of each separate portion as a group define grooves of equal dimensions within their own group.
Claim 6
Dependent Claim
177 words
A ground contacting element for covering substantially the entire bottom surface of a shoe or the like comprising a resilient body adapted to be secured to the base of a shoe, said resilient body having a forward portion and a rearwardly disposed portion, one of said portions having a plurality of straight transversely extending flexible thin fins, said fins of said one portion having front and rear surfaces that are parallel to each other and parallel to adjacent faces of adjacent fins, the other of said portions having a plurality of straight transversely extending flexible thin fins, said fins of said other portion having front and rear surfaces that are parallel to each other, and the extension of planes containing said faces of said fins of said one portion intersect the extension of the planes containing said faces of said fins of said other portion, all of said fins being of substantially uniform thickness throughout the length thereof, and said fins of each separate portion as a group define grooves of equal dimensions within their own group.
Claim 7
Dependent Claim
25 words
A ground contacting element as set forth in claim 4 wherein said surfaces of said fins make an angle of 45° with a horizontal plane.
Claim 8
Dependent Claim
30 words
A ground contacting element as set forth in claim 5 wherein the ratio of the height of said fin to the thickness of said fin is approximately 4.5 to 1.
