7 months after purchase
Size: 8.5 Wide, Color: Black
7 months after purchase. Still look good. Very comfortable right out of box. Outside edges of heels chipped away almost right away. Never seen that before. Brittle/ bad choice of rubber or design? Leather upper still looks pretty good with a little polish. Rubber soles wearing very well.
