Super cute, but you could break your ankle
Size: 8.5, Color: Chestnut Suede
I gave these a five star because they are very comfortable and very stylish. However, beware you could potentially roll or break your ankle in these. There is not a lot of support and they feel mushy and you may just be walking through your house and your ankle will be on the ground.
