Off-white & black geometric design- comfy leather flats from Madrid, Spain

Elegant and modern design. Leather is like a second skin, once you experience wearing it, it is hard to return to man-made media. Flats are good for the health of the back and legs and the lines of those shoes does not break the elegance of what you wear, on the contrary, they enhance it. So elegance and beauty without pain!!! Purchased in 1990 at El Corte Ingles in Madrid. Worn them once back home to realize they were too small 🥲. Kept them as memento but now would like someone who loves beautiful things and wears a size 8 M to enjoy them. 😁All fine leather except the soles, which are made of man made material. The heel coverage will probably need to be changed as they dry over the years. Upon closer observation: very superficial rub on a couple of areas: probably due to when I tossed them to reach other pairs of shoes. See pictures for further info on condition which is very good vintage. Colour of eggshell but from a distance it looks white ( plus the black) Note that pictures were taken at sunset near a window to get the natural light so the red you see is from the colours of the sun!
