I have this shoe in all colors and they seem to be made of thin leather. not sure if the antiquing process did something to the leather but after wearing the gray pair once the shoe showed shadows of  a lightened leather on the exterior of both feet and across the bridge of the foot  making the shoe have the appearance of looking like they were worn for a year straight on a wide foot. So bad actually I won't wear them again ,they look terrible. A shame for a brand new shoe! First time I have encountered a quality issue of this magnitude with Born. I did write to them as I buy this brand frequently and got no response, and indication of how they value their customers? I hope not.
