Claim 9
Dependent Claim
145 words
An insert support envelope which comprises: a pair of superposed plastic sheets, each having a generalized foot shape being marginally welded to each other and welded also along a line internally of said marginal welds to delineate a heel positioner portion and an arch support portion, said superposed plastic sheets together with said marginal welds and internal weld line forming a discrete heel positioner and support chamber and a discrete arch support chamber, said internal weld line spacedly separating said discrete heel positioner and support chamber from said discrete arch support chamber whereby pressure applied to one of said chambers is not transmitted to the other of said chambers; a first conduit means communicating only with said heel support chamber; and a second conduit means communicating only with said arch support chamber, said second conduit means serving as an overflow pocket for excess plastic fluid.
Claim 10
Dependent Claim
145 words
An insert support envelope which comprises: a pair of superposed plastic sheets, each having a generalized foot shape being marginally welded to each other and welded also along a line internally of said marginal welds to delineate a heel positioner portion and an arch support portion, said superposed plastic sheets together with said marginal welds and internal weld line forming a discrete heel positioner and support chamber and a discrete arch support chamber, said internal weld line spacedly separating said discrete heel positioner and support chamber from said discrete arch support chamber whereby pressure applied to one of said chambers is not transmitted to the other of said chambers; a first conduit means communicating only with said heel support chamber; and a second conduit means communicating only with said arch support chamber, said second conduit means serving as an overflow pocket for excess plastic fluid.
Claim 11
Dependent Claim
94 words
An insole support which comprises: a plastic sheet; a discrete heel positioner and support section formed of molded plastic and affixed to said plastic sheet; and a discrete arch support section formed of molded plastic and affixed to said plastic sheet, immediately adjacent to said heel support section, both said heel support section and said arch support section being spacedly separated by an area of said plastic sheet itself, which area is essentially free of molded plastic material whereby pressure applied to one said section is not transmitted to the other of said section.
Claim 12
Dependent Claim
94 words
An insole support which comprises: a plastic sheet; a discrete heel positioner and support section formed of molded plastic and affixed to said plastic sheet; and a discrete arch support section formed of molded plastic and affixed to said plastic sheet, immediately adjacent to said heel support section, both said heel support section and said arch support section being spacedly separated by an area of said plastic sheet itself, which area is essentially free of molded plastic material whereby pressure applied to one said section is not transmitted to the other of said section.
