I purchased these but ended up never wearing them, so they've been in storage. Since the details are unknown, I'm offering them at a low price. Color: Black Size: 37.5 (Italian size), approximately 23.5 cm Material: Probably synthetic leather The sides at the back are made of elastic, providing stretch. You can easily wear them without a zipper. They have a low heel, a flat heel, so they seem comfortable and less tiring. Price valid until December 23rd.
