Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
A shoe construction comprising: a shoe sole having upper and lower surfaces, the upper surface over the length and width of the upper surface following the anatomical contour of the undersurface of the human foot and the sole defining a forwardmost toe region, an intermediate ball region, an intermediate shank region and a rearmost heel region; and air pocket members distributed over the length of said sole such that an air-pocket member is incorporated into each of said regions, each of said air pocket members being a unitary structure independent of the other air-pocket members and formed from top and bottom layers welded about their peripheries, each of the air-pocket members in each region being spaced from the air pocket members in the adjacent regions and from the peripheral edge of said upper anatomical surface, said spacing between the air-pocket members and between the air-pocket members and the peripheral edge of the anatomical upper surface forming a skeleton of the anatomical surface, whereby said shoe sole provides cushioning and orthopedic support to the user's foot.
Claim 2
Dependent Claim
175 words
A shoe construction comprising: a shoe sole having upper and lower surfaces, the upper surface over the length and width of the upper surface following the anatomical contour of the undersurface of the human foot and the sole defining a forwardmost toe region, an intermediate ball region, an intermediate shank region and a rearmost heel region; and air pocket members distributed over the length of said sole such that an air-pocket member is incorporated into each of said regions, each of said air pocket members being a unitary structure independent of the other air-pocket members and formed from top and bottom layers welded about their peripheries, each of the air-pocket members in each region being spaced from the air pocket members in the adjacent regions and from the peripheral edge of said upper anatomical surface, said spacing between the air-pocket members and between the air-pocket members and the peripheral edge of the anatomical upper surface forming a skeleton of the anatomical surface, whereby said shoe sole provides cushioning and orthopedic support to the user's foot.
Claim 3
Dependent Claim
33 words
A shoe construction in accordance with claim 1 wherein: said upper surface includes at each location at which there is an air-pocket member a cavity in which said air-pocket pocket member is disposed.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
65 words
A shoe construction in accordance with claim 2 wherein: said air-pocket members each have a longitudinal extension and a lateral extension, said air-pocket members in said said heel and shank regions having their longitudinal extensions along the length of said shoe sole and said pocket members in said ball and toe regions having their longitudinal extensions angled relative to the length of said shoe sole.
Claim 6
Dependent Claim
45 words
A shoe construction in accordance with claim 4 wherein: the lower surface of said shoe sole comprises first, second, third and fourth crest regions connected by valley regions, said first, second, third and fourth crest regions underlying said toe, ball, shank and heel regions, respectively.
Claim 7
Dependent Claim
26 words
A shoe sole in accordance with claim 5 wherein: said air-pocket members are of substantially the same configuration and hold substantially the same amount of air.
Claim 8
Dependent Claim
