The ornamental design for a shoe, as shown and described.
FIG. 1 is a front perspective view of a shoe showing my new design;
FIG. 2 is a side view thereof; and,
FIG. 3 is a rear view thereof.
The solid line that is not immediately adjacent to the shaded area is claimed. The even-length broken line that is within the shaded area forms no part of the claimed design. The uneven-length broken lines immediately adjacent to the shaded area define the bounds of the claimed design and form no part thereof. The eight unshaded regions within the shaded area that are demarcated by solid lines form no part of the claimed design. The uneven-length broken lines depicting the remainder of the shoe show features that form no part of the claimed design.
