YSL YVES SAINT LAURENT Vintage Sling back Heels

Vintage YSL studded sling back low heels. Comparable as have these dated to the late 70s disco era but I can’t confirm. Either way, these are a great classic addition to any closet! -Red leather -Made in Italy - Brass studded toe detail (all intact) In good vintage condition, there is some marks on the heel (see photos) and some wear at the bottom. The sling back part has an interior striping to hold them in place, it feels a bit dry to me but I’m not sure if it’s supposed to be that way or not. Please ask any additional questions, I’m happy to answer! Size 6 N Approx measurements: Heel 3.5” Length 10 1/4” Width 3”
