aka..open shoes. i am a fun of these over pumps , sneakers or boots (aka closed shoes ). They are great for showing off you ankles and well manicured nails. They also let your breathe !! . Plus they match with everything. A few have been fads e.g gladiators but have eventually been refined and are here to stay. Whether flat or high heeled , i think it’s safe to say that every girl should have at least two pairs of these babies.
