These square-toe Prada loafers were purchased over 20 years ago and have been sitting in a shoe cabinet ever since. I'm not sure of the size as the marking is unclear, but I believe they are 27cm. I'm unsure of the exact purchase date, but I think it was around 2002. They have a substantial weight to them. Both heels show wear. There is no Prada stamp inside, for some reason, but the Prada stamp is on the sole. My memory is hazy, but I probably bought these authentic shoes at a select shop in Paris or London. If you are concerned, please use a verification service. These are old, used shoes, so please refrain from purchasing if you are overly concerned about their condition.
