Abstract: There is provided a sock formed on a circular knitting machine. The sock has a tubular body including a cuff defining an opening to receive the foot of the wearer and includes a toe portion, a foot portion, a heel and a relatively narrow looped tab loop comprising a knit strip integrally knit onto the opening at the top of the tubular body and including opposed ends. The knit strip is folded intermediate the ends to provide a loop having inner and outer layers with open opposed sides, and the ends of the inner and outer layers of the looped tab and connecting the same to the cuff whereby the looped tab extends downwardly therefrom and is adapted to be disposed on the outside of the shoe. The sock knit strip comprises a plurality of knit courses of equal length having opposed selvage ends and the length of the knit courses forming the looped tab are preferably less than one-fourth the length around the opening.
