I claim the ornamental design for footwear, as shown and described.
FIG. 1 is a front perspective view of footwear, showing my new design;
FIG. 2 is a right side view thereof; and,
FIG. 3 is a rear perspective view thereof.
The short broken lines outside of the claimed region are included for illustrating environmental structure and form no part of the claimed design. The broken “dash-dot-dash” patterned lines are break lines which form no part of the claimed design. The bold, short broken lines contained within the claimed region represent stitching, and are part of the claimed design.
