Abstract
Abstract An inner liner is provided for a shoe that makes the shoe waterproof and at the same time allows the foot to breathe. To accomplish this purpose, such a liner is constructed of a material that is impervious to water but is pervious to perspiration vapors. The liner comprises a sock-like configuration shaped to fit within a shoe upper and attached to the top and bottom portions of the upper, such liner having fold portions similar to fold portions at the front of the shoe to allow expansion and contraction thereof when the shoe is placed on the foot and removed. The liner may also employ a novel seam in joined portions thereof, and its particular structure allows it to be combined with all conventional types of shoe constructions.

A shoe construction comprising: (a) a sole; (b) an integral upper having a bottom portion secured to said sole, panel portions extending upwardly from said bottom portion, a tongue and gussets connecting said tongue to said panel portions, said upper including a top opening arranged to receive a foot and defined by the edges remote from said sole of said panel portions, tongue and gussets; and (c) a sock-like liner disposed in said upper, said liner being formed of material which is impervious of water, but pervious to perspiration vapor and being secured to said upper only proximate the top opening thereof.
Claim 2
Dependent Claim
102 words
A shoe construction comprising: (a) a sole; (b) an integral upper having a bottom portion secured to said sole, panel portions extending upwardly from said bottom portion, a tongue and gussets connecting said tongue to said panel portions, said upper including a top opening arranged to receive a foot and defined by the edges remote from said sole of said panel portions, tongue and gussets; and (c) a sock-like liner disposed in said upper, said liner being formed of material which is impervious of water, but pervious to perspiration vapor and being secured to said upper only proximate the top opening thereof.
Claim 3
Dependent Claim
36 words
The shoe construction of claim 1 wherein said liner includes toe, heel, side tongue, gussett and bottom portions and is open at the top, the bottom portion of said liner being adhesively fixed to said sole.
Claim 4
Dependent Claim
24 words
The shoe construction of claim 2 wherein said bottom portion has a longitudinal opening and is adhesively fixed to adjacent sides of said sole.
