FIG. 1 is a front perspective view of a portion of a shoe upper showing my new design;

FIG. 2 is a side view thereof; and,

FIG. 3 is a rear perspective view thereof.

The difference in shading indicates a contrast of appearance and does not depict any particular color, texture, or material. The broken lines immediately adjacent to the shaded area represent an unclaimed boundary of the design. The broken line showing of the remainder of the shoe is for illustrative purposes only and forms no part of the claimed design.
