Saint Laurent Bianca studded platform sandals in black leather with silver hardware and studs, they come in their own box, the official name is Bianca T-Bar 115.
The heels and platforms have some scuffing, I had it resealed by my cobbler, on the left shoe on the inside 2 studs are missing, but because it is on the inside it is not visible and can easily be replaced.
Heel height is 12.5 cm, platform 3 cm, insole length 26 cm
EU size 39 which is a generous UK 6
