These pumps are great for both business and evening events. To wear them, simply slip your feet in and adjust the fit. Since they're true to size, you shouldn't have any fitting issues. When walking, take small steps at first to get used to the 4 - inch heel. As for maintenance, use a soft cloth to wipe off any dirt or dust. Avoid getting them wet as the faux leather might be damaged. Remember, this is a final sale item. If you have any concerns about the size or style, contact us before you buy. You can only exchange it for store credit, not get a refund.
