Steve Madden heels

Received this pair of Steve Madden studded heels for women on a trade do not know if they were worn or how many times they’re worn if so because they look so new so I can’t tell if they’re worn or not see pictures to figure this out for yourself . But as far as my eyesight can see they don’t appear to have been worn possibly tried on? Also they appear to be a suede or a suede like fabric with metal hardware as the studs
