Soft calf leather is a supple and delicate material and will generally show scuffing when in contact with abrasive materials. For best results, avoid long-term exposure to water. Shoes can be refurbished as needed with store-bought polish, or by a professional, for more thorough care. This shoe is made with a 100% crepe sole, which after some time or with exposure to extreme heat, can become sticky and pick up debris. The crepe sole can also commonly flatten and become a bit more molded to the shape of your foot. This is considered a natural byproduct of this material.
