Size is 24.5, but for those who wear 24cm. Unfortunately, they were too tight for me, so I'm selling them. They are black, but might be dark navy, please refer to the photos. I haven't worn them outside. Only tried them on. These are 3.5cm heel shoes with a cross-strap design, and I think they'll be comfortable to wear. - Color: Black - Design: Cross-strap - Sole shape: 3.5cm heel, height that won't make you tired easily. Thank you for looking.
