VTG 80’s round toe geometric b&w flats Size 8 1/2

Vintage 80’s era rounded toe slip on flats in white, black and silver geometric abstract pattern. Size 8.5 AA I wear a 7.5 and they feel narrow and like a whole size too big. I’m not sure what they’re made of- possibly vinyl or a simulated leather They’re in used vintage condition and the “leather” areas are starting to crack a bit so I’d say they’d be best for a photo shoot or a place where you’re not walking a bunch Any questions, feel free to ask!
