Two-ply athletic sock
First Claim
1. A sock comprising:
- (a) a first inner ply of knit construction inserted within a second, outer ply of knit construction, said inner ply having a first surface made of material that is sufficiently hydrophobic to comprise means for carrying moisture away from the skin of a wearer, which is capable of relatively high friction with the skin of the wearer and a second surface having relatively low frictional characteristics, said second ply having a first surface positioned adjacent the second surface of said first ply and having relatively low frictional characteristics and also having a second surface having relatively high friction characteristics and being formed of a material which is sufficiently hydrophilic to comprise means for holding normal amounts of perspiration from the skin of the wearer.

Abstract
A knit sock, especially for jogging or other athletic activity, has a foot portion consisting of a first inner layer or ply disposed inside a second outer layer or ply. The first ply of the foot portion has an inner surface adapted to contact the skin formed principally of yarns having high frictional characteristics, high thermal conductivity, and low moisture regain (hydrophobic). Its opposed surface is formed principally of yarns having relatively low frictional characteristics. The second ply has an inner surface which has low frictional characteristics and its outer surface is formed of yarns having relatively high frictional characteristics and high moisture regain (hydrophilic). The latter surface may also be formed with terry loops to enhance its shock-absorbing construction as well as to increase its moisture absorbing capacity.

8. A knit sock comprising a foot portion which includes:
-
(a) a first inner ply of knit construction which includes; (1) a first surface adapted to be positioned in contact with the skin of the wearer and formed principally of yarns having high thermal conductivity, low moisture regain in sufficiently hydrophobic material to comprise means for carrying moisture away from the skin of a wearer, and being frictionally cohesive with the skin, and (2) a second, opposed surface formed principally of yarns having frictional characteristics substantially lower than the frictional characteristics of said first surface, (b) a second outer ply of knit construction which includes; (1) a first surface positioned adjacent the second surface of the first ply and also having low frictional characteristics relative to said first surface of said first ply, and (2) a second opposed surface formed of yarns having relatively high frictional characteristics and having high moisture regain in sufficiently hydrophilic material to comprise means for holding normal amounts of perspiration from the skin of a wearer, said inner ply being slightly smaller than said outer ply to enable it to be inserted within said outer ply.
