Abstract

A double-layered sock according to the invention includes an inner sock made of a moisture-permeable material such as polypropylene and an outer sock that absorbs such moisture. The inner sock is interposed between the skin of the foot and the absorbed moisture, providing enhanced warmth and comfort. The inner and outer layers are secured together, such as by sewing at the toe portion of each to form the double sock.

Claims

1. A method for making a sock including a main portion and a vent panel of lighter weight than said main portion, the vent panel being located on the top of the sock, comprising the steps of:

circularly knitting a tubular blank using a doubled yarn comprising a first yarn and a second yarn, the blank having a pair of open ends;

selectively omitting the second yarn during knitting of the blank to form a vent panel proximate one end of the blank; and

sewing said one end of the blank closed to form said sock, wherein a bottom of the sock and portions of the sock adjoining the vent panel on a top and sides of the sock, near its toe end, are part of the main portion of the sock and are of heavier weight than the vent panel.

2. The method of claim 1, wherein the second yarn comprises polypropylene.

3. The method of claim 1, wherein the first yarn comprises stretch nylon.

4. The method of claim 1, wherein the knitting step further comprises plaiting said second yarn on top of said first yarn.

5. The method of claim 1, wherein the omitting step further comprises carrying the second yarn behind the first yarn to form the vent panel.

6. The method of claim 1, wherein said omitting step further comprises sizing the vent panel to overlie a wearer'"'"'s toes.
