Abstract
Abstract A sole construction such as used on overshoes, boots or shoes having a resilient planar body with a plurality of spaced flexible fins that extend transversely across the body. The fins are evenly spaced and are relatively thin and of the same dimension as the grooves therebetween. All fins are identical and are inclined relative to a horizontal plane. The fin structure is applied to the sides of the boot structure to reduce mud pick-up through the ability of the fins to trap air between adjacent fins.

Claim 1
Independent Claim
136 words
In a shoe construction having a shoe upper, said upper having side portions, said shoe having a bottom surface, said upper portion being integrally formed with said bottom surface, said bottom surface having a sole portion and a heel portion, each of said sole and heel portions having a plurality of transversely extending flexible fins, all of said fins on said heel and sole portions extending downwardly and at an acute angle therefrom, said side portions having a plurality of fins extending along the peripheral portions adjacent to said sole and heel portions, all of said fins on said side portions making an acute angle with respect to its juncture with said side portion, and all of said fins on said respective heel, sole and side portions cooperative with adjacent fins to define a groove therebetween.
Claim 2
Dependent Claim
136 words
In a shoe construction having a shoe upper, said upper having side portions, said shoe having a bottom surface, said upper portion being integrally formed with said bottom surface, said bottom surface having a sole portion and a heel portion, each of said sole and heel portions having a plurality of transversely extending flexible fins, all of said fins on said heel and sole portions extending downwardly and at an acute angle therefrom, said side portions having a plurality of fins extending along the peripheral portions adjacent to said sole and heel portions, all of said fins on said side portions making an acute angle with respect to its juncture with said side portion, and all of said fins on said respective heel, sole and side portions cooperative with adjacent fins to define a groove therebetween.
Claim 3
Dependent Claim
97 words
An overhoe construction having an upper portion and a sole attached thereto, said upper including a toe portion and a heel portion, said upper including a pair of side portions merging into said heel and said toe portions, said sole having a plurality of linear transversely extending flexible fins, said fins inclined downwardly at an acute angle along the entire length thereof, said side portions having a plurality of horizontally extending flexible fins that lie in parallel rows with grooves between rows thereof, and said fins on said side portions slanting downwardly and away from said overshoe.
Claim 4
Dependent Claim
97 words
An overhoe construction having an upper portion and a sole attached thereto, said upper including a toe portion and a heel portion, said upper including a pair of side portions merging into said heel and said toe portions, said sole having a plurality of linear transversely extending flexible fins, said fins inclined downwardly at an acute angle along the entire length thereof, said side portions having a plurality of horizontally extending flexible fins that lie in parallel rows with grooves between rows thereof, and said fins on said side portions slanting downwardly and away from said overshoe.
Claim 5
Dependent Claim

An overshoe as set forth in claim 2 wherein each of said fins of said side portions have a pair of parallel surfaces.
Claim 6
Dependent Claim
41 words
An overshoe as set forth in claim 3 wherein said fins of said side portions define grooves between adjacent rows, and said grooves have a width and depth that is equal to the thickness and height of said adjacent fins, respectively.
Claim 7
Dependent Claim
41 words
An overshoe construction as set forth in claim 2 wherein each of said fins of said side portions have a lobe at the forwardmost portion thereof and a thin narrow portion at the juncture of said fin to said side portion.
Claim 8
Dependent Claim
145 words
An overshoe construction having an upper portion and a sole attached thereto, said upper including a toe portion and a heel portion, said upper including a pair of side portions merging into said heel portion and said toe portion, said sole having a plurality of linear transversely extending thin flexible fins, said fins on said sole portion inclined downwardly at an acute angle along the entire length thereof, each of said fins having a front and a rear surface, said surfaces being parallel to each other and parallel to adjacent surfaces of adjacent fins, each of said fins being of uniform width for the entire height thereof, and each fin cooperating with adjacent fins defining a groove therebetween, and said side portions having a plurality of rows of flexible fins, said rows of said fins of said side portions lying in a generally vertical plane.
Claim 9
Dependent Claim
145 words
An overshoe construction having an upper portion and a sole attached thereto, said upper including a toe portion and a heel portion, said upper including a pair of side portions merging into said heel portion and said toe portion, said sole having a plurality of linear transversely extending thin flexible fins, said fins on said sole portion inclined downwardly at an acute angle along the entire length thereof, each of said fins having a front and a rear surface, said surfaces being parallel to each other and parallel to adjacent surfaces of adjacent fins, each of said fins being of uniform width for the entire height thereof, and each fin cooperating with adjacent fins defining a groove therebetween, and said side portions having a plurality of rows of flexible fins, said rows of said fins of said side portions lying in a generally vertical plane.
