The perfectly wearable everyday wedge, Sereno's soft materials and footbed contoured for balance and stability make way for modern comfort. Uppers: Nubuck. Footbed: Removable Microfiber Covered EVA. Outsole: Rubber. Heel Height: 2.5". Platform Height: 0.875". Biomechanically designed to hug your arches, Vionic Technology helps support natural alignment from the ground up. For the greatest comfort, we recommend wearing your new Vionic footwear for just a few hours for the first few days to allow your feet to adjust to the new level of orthotic comfort and support. Within one to two weeks you should find the product completely comfortable and supportive. To preserve the appearance of your Vionic' s, we recommend that you clean, if needed, using a dry, cotton cloth to wipe away dirt or dust. If they become wet, please allow them to dry naturally. We recommend that you test any cleaning product by applying a small amount to a discreet area and allowing it to dry. Do not use cleaners which contain acid or detergents, as they may damage and prematurely age the leather. Please Note: ***I wear a size 8.5M in all my shoes and these ran big on me. They run more like a size 9M and the width feels good. Listed as a size 9 due to running big.*** No flaws New without box
