Steve Madden shoes... 10+ years old!

Is that considered vintage? Anyway... these are my sister's old middle and high school shoes she hasn't worn in YEARS. She's 30 now. You get the picture. Now, as shown, you can see some of the dirt marks in the inside sole of the shoe, and some scuff marks. However, they are still in great condition. Says they're made out of man made materials, so I'm going to assume that they are vegan/vegetarian. No trades! Reasonable negotiations.
