The mark consists of a three-dimensional configuration of a non-slip design comprising a semicircular-shaped non-slip portion on the toe area of the sock along with an opposing semicircular-shaped non-slip portion on the heel area of the sock as applied to the bottom of a sock, said sock either being an open toe sock or a closed toe sock. The broken lines depicting the outline of an exemplary sock indicate the placement of the mark on the goods, and are not a part of the mark.
