ABSTRACT:
The sock has at least a foot portion consisting of a first inner layer or ply disposed within and attached to a second outer layer or ply. The first or inner ply has (a) an inner (next-to-the-foot) surface comprising a plurality of moisture-absorbing fibers such as cotton fibers around which a yarn such as a nylon yarn is spirally wound and also has (b) an outer surface comprising yarns of nylon, for example, having relatively low friction characteristics compared with said inner surface. The second or outer ply, has (a) an inner surface comprising yarns of nylon, for example, which also have relatively low friction characteristics and (b) an outer surface plaited on the yarns of the inner surface comprising a plurality of moisture-absorbing fibers such as cotton around which a yarn such as nylon is spirally wound. The interface between the surfaces, having relatively low friction characteristics, permits the inner ply (in use) to slide relative to the outer ply for greater foot comfort and avoidance of blisters.
