To use these Vionic Caroll ballet flats, simply slip your feet in. They're perfect for daily wear, whether you're running errands or going out for a casual event. As for maintenance, use a soft, dry cloth to wipe off dirt regularly. If the footbed gets dirty, you can remove it and gently wash it with mild soap and water, then let it air - dry. Avoid exposing the shoes to extreme heat or direct sunlight for long periods, as this can damage the leather. Also, be careful not to scratch the outsole on rough surfaces to maintain its traction.
