To use these Mary Jane shoes, just slip your feet in and you're good to go. They're true to size, so pick your regular shoe size. When walking, the 6 - inch wedge platform will give you a bit of height, but be careful as it's a bit high. For maintenance, use a soft cloth to wipe the white faux leather clean. Keep them in a cool, dry place when not in use. Avoid getting them wet for long periods to prevent damage to the faux leather.
