mule
The mule is a sandal or shoe without a back. That means, when you wear mules, your heel is exposed.
Mules can be casual for lounging in. Comfortable mules could be worn like slippers around the home.
At the other extreme, the elaborately designed, beaded or sequined mules go very well with an evening gown. Glamourous enough for red carpet occasions.
