The ornamental design for a shoe upper, as shown and described.
FIG. 1 is a side view of a shoe showing my design;
FIG. 2 is a front perspective view thereof; and,
FIG. 3 is a rear perspective view thereof.
The long-and-short broken lines form an unclaimed boundary around at least a portion of the claimed subject matter, and form no part of the claim. The even-length broken lines, which show the remainder of the article, are directed to environment, represent unclaimed subject matter, and form no part of the claimed design.
The contrast in shading within the claimed boundary represents a contrast in appearance only.
