RARE Vintage Apropos Hand Made 60's round heeled slide size 5.5

I've held on to these for well over 40 years now. They are just so unique. Very soft, purple kid leather, hand made slide with a front lace up detail, and really unique, almost round heel. Hand numbered inside style information. There is a bit of scuffing on the back edge of the heel, but otherwise excellent leather condition. These are clearly special shoes for a very particular retro outfit.
