The ornamental design for a sock, as shown and described.
FIG. 1 is a left side elevational view of a sock showing my new design, the
right side being a mirror image thereof;
FIG. 2 is an enlarged fragmentary left side elevational view;
FIG. 3 is a view like FIG. 1 of another embodiment of a sock showing my new
design, wherein the cuff markings are taller than those of FIGS. 1 and 2,
the side stripe is doubled and the outline of the pattern between the rear
of the sock and the stripe is "heavier" than that of FIGS. 1 and 2, the
right side being a mirror image of this side; and
FIG. 4 is an enlarged fragmentary right side elevational view of the FIG. 3
sock.
The pattern of the sock is achieved with a yarn of a color different from
that of the rest of the sock.
