FIG. 1 is a front left perspective view of a shoe showing my new design;
FIG. 2 is a top view of the design shown in FIG. 1; and,
FIG. 3 is a front right perspective view of the design shown in FIG. 1.
The bottom of the shoe forms no part of the claimed design. The areas within the solid lines and inside the dash-dot-dash lines form the claimed design. The dash-dot-dash lines illustrate boundary and form no part of the claimed design. The broken lines shown in the figures are included for the purpose of illustrating portions of the shoe that form no part of the claimed design.
