These Heels have an ankle boot or bootie look to them with a wide crossover strap and buttons (buttons for style only not functional). They are secure on your feet so they're easy to wear all day. They have elastic at the top to give a little flex. They look great with dress casual business attire. The material is an easy to clean mild textured matte black with PU material accents to add a shiny contrast near the edges, platform, and heel. Any white you see in the photos was my lighting picking up the fuz from my blanket used for the background. They are nearly new, only worn a few times for indoor desk work and meetings in a carpeted area. No damage. A workable 4 inch heel with a 1/2 inch platform toe. Good for longer wear.
