I claim the ornamental design for a shoe sole, as shown and described.
FIG. 1 is a perspective view of a shoe sole according to an embodiment of the design.
FIG. 2 is a left side view of the shoe sole.
FIG. 3 is a right side view of the shoe sole.
FIG. 4 is a front view of the shoe sole.
FIG. 5 is a rear view of the shoe sole.
FIG. 6 is a bottom view of the shoe sole; and,
FIG. 7 is a top view of the shoe to which the shoe sole is attached.
The claimed ornamental design is shown in solid lines and, on the sole portion of the shoe, in broken lines to depict stitching. Dashed lines in the drawings on the upper portions of the shoe sole are for illustrative purposes only and form no part of the claimed design.
