ABSTRACT:
A conventional shoe which comprises a shoe upper of continuous and uninterrupted material attached to an outer sole has its shoe upper lined with an air-cooled, breathable shoe liner comprising an outer knit layer of hydrophilic material, an inner knit layer of hydrophobic material, and monofilament yarns of hydrophobic material extending between and interknitted with the outer and inner layers for maintaining an air chamber therebetween, such that moisture from the foot of the wearer is transmitted by the inner layer and the monofilament yarns through the air chamber and is absorbed by the outer layer and passes into the shoe upper to be dried by the outer air.
