I claim 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 left side view thereof;
FIG. 3 is a rear perspective view thereof; and,
FIG. 4 is a front view thereof.
The dot-dot-dash broken line adjacent to the shaded area represents a boundary of the claimed design and forms no part thereof. The broken lines depicting the remainder of the shoe show features that form no part of the claimed design.
