Abstract
Abstract A profiled outer sole for shoes, especially sport shoes, made in a mold and consisting of rubber or other material having rubber-elastic properties, which is provided with profiled projections laterally delimiting the tread surface of the outer sole; the profiled projections, in turn, are provided with groove-shaped slots extending obliquely to the respective tangential plane tangential to the outer boundary surfaces of the individual profiled projections within the bisecting plane thereof.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
174 words
A shoe with an inner sole and an outer sole constructed from a material having rubber-elastic properties, the outer sole including profiled projection means arranged along lateral sole edges, characterized in that the profiled projection means laterally delimit a tread surface of the outer sole, each of the profiled projection means are provided with at least two V-shaped slots extending obliquely to a tangential plane at outer boundary surfaces of the individual profiled projection means substantially in a bisecting plane thereof, said at least two V-shaped slots are nested one within the other, in that the outer sole is provided with inner profiled projections having hollow spaces open in the direction toward the inner sole within an area of a front sole, which hollow spaces are surrounded by the profiled projection means, in that the inner profiled projections project in an unloaded condition of the outer sole with respect to the tread surface formed by the edge profiling, and in that an inner sole covering the hollow spaces of the profiled projections is air-permeable.
Claim 2
Dependent Claim
174 words
A shoe with an inner sole and an outer sole constructed from a material having rubber-elastic properties, the outer sole including profiled projection means arranged along lateral sole edges, characterized in that the profiled projection means laterally delimit a tread surface of the outer sole, each of the profiled projection means are provided with at least two V-shaped slots extending obliquely to a tangential plane at outer boundary surfaces of the individual profiled projection means substantially in a bisecting plane thereof, said at least two V-shaped slots are nested one within the other, in that the outer sole is provided with inner profiled projections having hollow spaces open in the direction toward the inner sole within an area of a front sole, which hollow spaces are surrounded by the profiled projection means, in that the inner profiled projections project in an unloaded condition of the outer sole with respect to the tread surface formed by the edge profiling, and in that an inner sole covering the hollow spaces of the profiled projections is air-permeable.
Claim 3
Dependent Claim
16 words

Claim 5
Dependent Claim
17 words
A shoe according to claim 1, characterized in that the inner projections are constructed as strip profiles.
Claim 6
Dependent Claim
25 words
A shoe according to claim 1, characterized in that the inner profiled projections are provided with side walls movable in the manner of a bellows.
Claim 7
Dependent Claim
33 words
A shoe according to claim 5, characterized in that only outer surfaces of the side walls of the inner profiled projections are provided with a bellows profile whereas inner surfaces thereof are smooth.
Claim 8
Dependent Claim
17 words
A shoe according to claim 1, characterized in that the inner profiled projections have different geometric shapes.
Claim 9
Dependent Claim
16 words
A shoe according to claim 7, characterized in that the inner profiled projections have different dimensions.
Claim 10
Dependent Claim
39 words
A shoe according to claim 1, characterized in that the inner profiled projections project by approximately the dimension of the wall thickness thereof disposed in the tread surface with respect to the tread surface formed by the edge profiling.
Claim 11
Dependent Claim
34 words
A shoe according to claim 1, characterized in that the inner sole consists of several layers and in that a layer located nearest the outer sole consists of a porous material compressible in volume.
Claim 12
Dependent Claim
33 words
A shoe according to claim 10, characterized in that the inner sole includes a compensating sole, an insole and a cover sole and in that the compensating sole consists of said porous material.
Claim 13
Dependent Claim
37 words
A shoe according to claim 11, characterized in that the insole follows the compensating sole in a direction toward an interior of the shoe, and in that the insole and the cover sole are provided with apertures.
Claim 14
Dependent Claim
37 words
A shoe according to claim 11, characterized in that the insole follows the compensating sole in a direction toward an inside of the shoe, and in that the compensating sole and the cover sole are constructed air-permeable.
Claim 15
Dependent Claim
32 words
A shoe according to claim 12, characterized in that the apertures of the insole and of the cover sole have a considerably smaller cross section than hollow spaces of the profiled projections.
Claim 16
Dependent Claim
27 words
A shoe according to claim 1, characterized in that the at least two V-shaped slots open in a direction toward a longitudinal axis of the outer sole.
Claim 17
Dependent Claim
30 words
