Abstract
Abstract A safety sole for a football shoe is described which substantially reduces injuries to a player''s ankle or knee without detracting from the shoe''s ability to provide the player with firm footing. Rather than the ground engaging cleats of the shoe being rigidly secured to the remainder of the shoe, they are secured thereto through a flat, zig-zag spring having a resistance to deformation chosen to prevent movement of the shoe with respect to the cleats under normal playing conditions, but enable limited, resisted movement of such shoe with respect to the cleats upon the shoe being subjected to lateral forces exceeding a predetermined value.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
92 words
A safety sole for a sport shoe comprising non-slip ground engaging means for anchoring the foot of a player against lateral movement with respect to a playing surface, and a resilient coupling securing said ground engaging means to the remainder of said shoe for limited movement of said shoe with respect to said ground engaging means upon said shoe being subjected to a lateral force exceeding a predetermined value, said resilient coupling limiting said movement to translational movement of said ground engaging means transversely with respect to the remainder of said shoe.
Claim 2
Dependent Claim
92 words
A safety sole for a sport shoe comprising non-slip ground engaging means for anchoring the foot of a player against lateral movement with respect to a playing surface, and a resilient coupling securing said ground engaging means to the remainder of said shoe for limited movement of said shoe with respect to said ground engaging means upon said shoe being subjected to a lateral force exceeding a predetermined value, said resilient coupling limiting said movement to translational movement of said ground engaging means transversely with respect to the remainder of said shoe.
Claim 3
Dependent Claim
110 words
A safety sole for a sport shoe comprising non-slip ground engaging means for anchoring the foot of a player against lateral movement with respect to a playing surface, and a resilient coupling securing said ground engaging means to the remainder of said shoe for limited movement of said shoe with respect to said ground engaging means upon said shoe being subjected to a lateral force exceeding a predetermined value, said resilient coupling being resistive to said limited movement and imparting a position restoring force to said shoe which increases directly with said limited movement to thereby provide gradual absorption of said force by the ankle and knee of the player.
Claim 4
Dependent Claim
110 words
A safety sole for a sport shoe comprising non-slip ground engaging means for anchoring the foot of a player against lateral movement with respect to a playing surface, and a resilient coupling securing said ground engaging means to the remainder of said shoe for limited movement of said shoe with respect to said ground engaging means upon said shoe being subjected to a lateral force exceeding a predetermined value, said resilient coupling being resistive to said limited movement and imparting a position restoring force to said shoe which increases directly with said limited movement to thereby provide gradual absorption of said force by the ankle and knee of the player.
Claim 5
Dependent Claim
30 words
The safety sole of claim 2 for a sport shoe wherein said resilient coupling includes a spring which is compressed by said limited movement to provide said position restoring force.
Claim 6
Dependent Claim
84 words
The safety sole of claim 3 for a sport shoe wherein said spring is a generally flat spring providing resistance to deformation transversely of said shoe, which spring is secured to said ground engaging means at spaced apart locations on opposite sides of the longitudinal axis of said shoe and to said shoe generally on said longitudinal axis, whereby said spring provides said increasing restoring force to said shoe in response to lateral forces on said shoe in either lateral direction with respect thereto.
Claim 7
Dependent Claim
39 words
The safety sole of claim 4 for a sport shoe wherein said spring is in the form of a metal rod which is bent from one side to the other and extends generally transverse with respect to said shoe.
Claim 8
Dependent Claim
61 words
The safety sole of claim 5 for a sport shoe wherein said non-slip ground engaging means includes a plate secured to said spring at said spaced locations on opposite sides of said longitudinal axis of said shoe, and a pair of cleats which extend outwardly from said plate at spaced transverse locations with respect to said shoe for said ground engagement.
Claim 9
Dependent Claim
79 words
The safety sole of claim 6 for a sport shoe wherein said non-slip ground engaging means includes spaced along the length of said shoe a plurality of said plates from which a pair of cleats extends and said resilient coupling includes for each of said plates one of said flat springs secured thereto at spaced locations on opposite sides of said longitudinal axis of said shoe, which springs are each secured to said shoe generally on said longitudinal axis.
