The ornamental design for a no show sock, as shown and described.
FIG. 1 is a perspective view.
FIG. 2 is a front view.
FIG. 3 is a rear view.
FIG. 4 is a slightly elevated right view.
FIG. 5 is a slightly elevated left view.
FIG. 6 is a top view.
FIG. 7 is a bottom view; and,
FIG. 8 is a perspective drawing showing environment of a left foot.
The sock on a right foot or last approximating the shape of a right foot would appear substantially as a mirror image of the views as shown in the drawing figures.
The broken line depicting a human foot in FIG. 8 is for the purpose of showing environment and forms no part of the claim.
