Yves Saint Laurent YSL Rive Gauche vintage knee high boots Black

Vintage Yves Saint Laurent Rive Gauche knee high black leather boots with platform and stiletto heel, Super soft leather, lined in taupe leather, zippers on the inside, the zippers are branded YSL.
I had the shoes with our cobbler who descuffed them, I requested that he uses the matte treatment as then if the buyer prefers them more shiny, they can simply use a shinnier shoe polish. Our cobbler is a traditional one, who has done a fabulous job (please see the pictures, however I would like to mention it for clarity)
The shoes are labeled 36 but come like a generous UK 4 with an insole length of 25 cm, HEELS 12 cm, platform 3.5 cm, bootleg 36 cm
