Madewell Frances Loafer Mule in Spotted Calf Fur. Size 7 Gently used and in great condition. A mule version of the best-selling loafer, these spotted calf hair slip-ons are such a no-brainer for work (but we'll be popping them on for the weekend too). Cushiness alert: extra layer of padding to make them even easier on the feet. 3/4" heel. Calf hair upper. Man-made sole.
