Abstract
Abstract Moisture control characteristics are imparted to the sock of the present invention by body yarn knit in successive courses throughout the leg and foot. A hydrophobic yarn is knit in plated relationship with the body yarn in partial courses extending throughout the sole, and hydrophilic yarn is knit in plated relationship with the body yarn in partial courses extending throughout the instep whereby moisture generated by the foot of the wearer is wicked and transported from the sole and into the instep to be evaporated therefrom. Cut free ends extend from the endmost stitch loops in wales along the juncture of the sole and the instep while cut free ends of the hydrophilic yarn extend from endmost stitch loops in wales along the juncture of the sole and instep so that the endmost stitch loops at opposite ends of the partial courses of the hydrophobic and hydrophilic yarns are formed in adjacent wales and are not knit in plated relationship with each other in the same courses.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
143 words
A sock including integrally knit leg and foot portions, said foot portion including a heel at one end, a toe at the other end, a sole extending between said heel and toe and extending around the lower half of said foot, and an instep joined along a pair of opposite sides to a corresponding pair of opposite sides of said sole and extending around the upper half of said foot, said sock comprising (a) body yarn knit in successive courses throughout said leg and foot, (b) hydrophobic yarn knit in plated relationship with said body yarn in partial courses extending throughout said sole, and (c) hydrophilic yarn knit in plated relationship with said body yarn in partial courses extending throughout said instep whereby moisture generated by the foot of the wearer is transported from said sole to said instep to be evaporated therefrom.
Claim 2
Dependent Claim
143 words
A sock including integrally knit leg and foot portions, said foot portion including a heel at one end, a toe at the other end, a sole extending between said heel and toe and extending around the lower half of said foot, and an instep joined along a pair of opposite sides to a corresponding pair of opposite sides of said sole and extending around the upper half of said foot, said sock comprising (a) body yarn knit in successive courses throughout said leg and foot, (b) hydrophobic yarn knit in plated relationship with said body yarn in partial courses extending throughout said sole, and (c) hydrophilic yarn knit in plated relationship with said body yarn in partial courses extending throughout said instep whereby moisture generated by the foot of the wearer is transported from said sole to said instep to be evaporated therefrom.
