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.
