The ornamental design for footwear, as shown and described.
1. Footwear
1.1 : Perspective
1.2 : Left
1.3 : Right
1.4 : Front
1.5 : Back
1.6 : Enlarged view of the callout 1.6 of view 1.1.
The model regards a footwear having a sole with a perimetric wall, which has a rough surface defined by irregular protuberances and relief streaks; the broken lines define the boundary of the footwear upper, which is attached to the sole, but it is shown for illustrative purposes only and forms no part of the claimed design. The dash-dot-dash lines of view 1.1 are a callout delineating a region of the footwear from which the enlarged view 1.6 is taken.
