Abstract
Abstract Footwear is provided for added comfort to the wearer by facilitating the removal and dissipation of perspiration from the foot of the wearer. The footwear has a knitted sock and a shoe in combination. The knitted sock has a toe portion formed of hydrophilic knit fabric and an instep portion adjacent the toe portion formed of hydrophobic knit fabric. Perspiration from the toe portion of the foot of the wearer is absorbed by the knit hydrophilic toe portion of the knitted sock and wicked therefrom by the hydrophobic knit instep portion of the knitted sock. The shoe has a tongue portion overlying and contacting the hydrophobic knit instamp portion of the knitted sock. The tongue portion of the shoe has overlying inner and outer fabric layers formed of hydrophilic fabric and an intermediate fabric layer positioned between the overlying inner and outer hydrophilic fabric layers. The intermediate fabric layer has a medial portion formed of a hydrophobic fabric layer and opposite side portions formed of hydrophilic fabric layers. The inner hydrophilic fabric layer overlies and, is in contacting engagement with the hydrophobic knit instep portion of the knitted sock. The perspiration from the hydrophobic knit instep portion of the knitted sock is absorbed by the overlying and contacting inner hydrophilic fabric layer and the hydrophilic fabric opposite side portions of the intermediate fabric layer and wicked therefrom by the contacting hydrophobic fabric layer medial portion of the intermediate fabric layer. The perspiration is then transferred from the hydrophobic fabric layer medial portion to the overlying outer hydrophilic fabric layer of the tongue portion of the shoe for evaporation therefrom to atmosphere.
