Abstract
Abstract A shock-absorbing athletic shoe having a foot-cushioning inner sole member to one face in which, and to at least a portion of the rim in which, is bonded an open-mesh web. The web includes elongated, interwoven stretch-resistant strands which are disposed at oblique angles relative to the shoe's long axis. These strands act as force-transmitters with respect to the sole member, and cause a localized foot-produced deformation in the member to be "distributed" to other regions in the member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
In an article of footwear including means defining a deformable foot-cushioning inner sole expanse portion bounded by a rim portion which is disposed at an angle relative to said expanse portion, plural elongated stretch-resistant strands distributed over at least a part of said expanse portion and folded over at least a part of said rim portion, and bonding means distributed over said expanse and rim portions producing force-transmission bonds between said portions and said strands along the lengths of the strands, whereby, with a wearer's foot tending to produce a localized deformation in said expanse portion, said strands distribute such deformation to other regions in said expanse portion and to regions in said rim portion through force transmission and distribution via said bonds.
Claim 2
Dependent Claim
123 words
In an article of footwear including means defining a deformable foot-cushioning inner sole expanse portion bounded by a rim portion which is disposed at an angle relative to said expanse portion, plural elongated stretch-resistant strands distributed over at least a part of said expanse portion and folded over at least a part of said rim portion, and bonding means distributed over said expanse and rim portions producing force-transmission bonds between said portions and said strands along the lengths of the strands, whereby, with a wearer's foot tending to produce a localized deformation in said expanse portion, said strands distribute such deformation to other regions in said expanse portion and to regions in said rim portion through force transmission and distribution via said bonds.
Claim 3
Dependent Claim
71 words
In an athletic shoe, a pair of deformable foot-cushioning inner sole members disposed in confronting face-to-face relationship, stretch-resistant elongated strand means distributed between the confronting faces in said members, and folded over the rim of one of said members, and means bonding said strand means to said faces and to said rim, whereby a deformation occurring at one location within said members tends to produce related deformations at other locations therein.
Claim 4
Dependent Claim
71 words
In an athletic shoe, a pair of deformable foot-cushioning inner sole members disposed in confronting face-to-face relationship, stretch-resistant elongated strand means distributed between the confronting faces in said members, and folded over the rim of one of said members, and means bonding said strand means to said faces and to said rim, whereby a deformation occurring at one location within said members tends to produce related deformations at other locations therein.
Claim 5
Dependent Claim
86 words
In an article of footwear including a deformable foot-cushioning inner sole member having an expanse portion responsive to foot-imparted pressure, and a perimetral rim portion joining said expanse portion at an angle thereto, shock-distributing mechanism comprising strand means including plural, elongated, spaced, substantially linear, stretch-resistant strands distributed at different angles relative to one another over at least a part of said expanse portion, and folded over at least a part of said rim portion and means bonding said strands along their respective lengths to said portions.
Claim 6
Dependent Claim
86 words
In an article of footwear including a deformable foot-cushioning inner sole member having an expanse portion responsive to foot-imparted pressure, and a perimetral rim portion joining said expanse portion at an angle thereto, shock-distributing mechanism comprising strand means including plural, elongated, spaced, substantially linear, stretch-resistant strands distributed at different angles relative to one another over at least a part of said expanse portion, and folded over at least a part of said rim portion and means bonding said strands along their respective lengths to said portions.
