Madewell The Harper Mule in Metallic Gold/Bronze Size: 7.5 Made of buttery soft metallic leather, this is a dressed-up take on our signature slip-on mules (with, yep, the same foot-hugging fit and oh-so-walkable stacked heel). Cushiness alert: We've added an extra layer of padding to make them even comfier. 2 1/2" heel. Leather upper and lining. Man-made sole. See photos for condition
