Beautiful black and white platform sandals

These are from Rachel Zoe and are just stunning. They feature a black tassel tie in the rear that allows for size and fit adjustment. They are marked a size 10/40; however, with the rear tie, they can fit up to a size 11/41 comfortably. The platform height is about 2 inches and the stiletto heel is about 6.25 inches.The upper is a black and white linen and suede combination. The bottoms are leather. Questions welcome. These would be a great addition to any wardrobe.
