PRADA Vintage Booties - Size 7.5-8.5 Excellent condition - Slipper-like Comfort

Prada leather slip-on shoe. Bought them decades ago when I was size 7.5-8, wore them a year ago when I was size 8.5. Can find no size markings. Check photos closely for signs of wear (slight wear on heels). No cuts, dings or slashes in the leather. Never worn in the rain/snow, never worn while driving. Worn mostly indoors like slippers. I took great care of these beauties!
