Abstract
Abstract An elastomeric shoesole designed specifically for athletic activities wherein the sole contains at the outer side of the heel and/or the inner side of the ball transversely-extending, longitudinally-spaced openings which extend to approximately the longitudinal center line and wherein the respective opposite sides are substantially solid, thereby allowing the sole to yield at the outer side of the heel end to a greater extent than at the inner side and at the inner side of the ball to a greater extent than at the outer side.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
An elastomeric shoe bottom comprising a unitary molded structure defining a forepart, shank and heel having an imperforate zone of less than half the thickness at the top side for attachment to an upper and an imperforate zone of less than half the thickness at the bottom side constituting a tread surface, said structure containing intermediate the imperforate top and bottom zones in the region of major impact at the outer side of the heel longitudinally-spaced, parallel openings extending from the outer side face transversely substantially at right angles to the longitudinal center line, but terminating short of the inner side face of the heel, said openings defining an area at the top side of the heel area at the outer side of the longitudinal center line of the heel which is less in area than the entire heel area which yields at a predetermined pressure to a greater degree than the area at the inner side of the longitudinal center line of the heel.
Claim 2
Dependent Claim
165 words
An elastomeric shoe bottom comprising a unitary molded structure defining a forepart, shank and heel having an imperforate zone of less than half the thickness at the top side for attachment to an upper and an imperforate zone of less than half the thickness at the bottom side constituting a tread surface, said structure containing intermediate the imperforate top and bottom zones in the region of major impact at the outer side of the heel longitudinally-spaced, parallel openings extending from the outer side face transversely substantially at right angles to the longitudinal center line, but terminating short of the inner side face of the heel, said openings defining an area at the top side of the heel area at the outer side of the longitudinal center line of the heel which is less in area than the entire heel area which yields at a predetermined pressure to a greater degree than the area at the inner side of the longitudinal center line of the heel.
Claim 3
Dependent Claim
159 words
An elastomeric shoe bottom comprising a unitary molded structure defining a forepart, shank and heel having an imperforate zone of less than half the thickness at the top side for attachment to an upper and an imperforate zone of less than half the thickness at the bottom side constituting a tread surface, such structure containing in the region of major impact at the ball at the inner side of the ball longitudinally-spaced, parallel openings extending from the inner side face transversely substantially at right angles to the longitudinal center line toward the outer side face, but terminating short thereof, said openings defining an area at the top side of the ball area at the inner side of the longitudinal center line of the ball which is less in area than the entire ball area which yields at a predetermined pressure to a greater degree than the area at the outer side of the longitudinal center line of the ball.
Claim 4
Dependent Claim
159 words
An elastomeric shoe bottom comprising a unitary molded structure defining a forepart, shank and heel having an imperforate zone of less than half the thickness at the top side for attachment to an upper and an imperforate zone of less than half the thickness at the bottom side constituting a tread surface, such structure containing in the region of major impact at the ball at the inner side of the ball longitudinally-spaced, parallel openings extending from the inner side face transversely substantially at right angles to the longitudinal center line toward the outer side face, but terminating short thereof, said openings defining an area at the top side of the ball area at the inner side of the longitudinal center line of the ball which is less in area than the entire ball area which yields at a predetermined pressure to a greater degree than the area at the outer side of the longitudinal center line of the ball.
Claim 5
Dependent Claim
27 words
An elastomeric shoe bottom according to claim 1 so structured that the yieldable area will yield at a pressure of from 11/2 to 31/2 times body weight.
Claim 6
Dependent Claim
15 words
An elastomeric shoe bottom according to claim 1 and 2 wherein the openings are continuous.
Claim 7
Dependent Claim
30 words
An elastomeric shoe bottom according to claim 4 wherein there are supporting walls between the openings and wherein the walls are of lesser thickness than the breadth of the openings.
Claim 8
Dependent Claim
31 words
An elastomeric .[.shoesole.]. .Iadd.shoe bottom .Iaddend.according to claim 1 .[.or 2.]. wherein the openings are arranged in upper and lower arrays with the openings in the upper and lower arrays alternating.
Claim 9
Dependent Claim
19 words
An elastomeric .[.shoesole.]. .Iadd.shoe bottom .Iaddend.according to claim 1 .[.or 2.]. wherein the openings are of triangular cross section.
Claim 10
Dependent Claim
22 words
An elastomeric .[.shoesole.]. .Iadd.shoe bottom .Iaddend.according to claim 1 .[.or 2.]. wherein an elastomeric tube is positioned in each of the openings.
Claim 11
Dependent Claim
26 words
An elastomeric .[.shoesole.]. .Iadd.shoe bottom .Iaddend.according to claim 6 wherein an elastomeric element is positioned in each of the openings of the upper array of openings.
Claim 12
Dependent Claim
26 words
An elastomeric .[.shoesole.]. .Iadd.shoe bottom .Iaddend.according to claim 6 wherein an elastomeric element is positioned in each of the openings of the lower array of openings.
