Black synthetic leather platform lace-up shoes. The inside is purple, and they have a zipper design. - Color: Black - Material: Synthetic leather - Size: M (23-23.5cm) - Sole Height: Platform approximately 9cm - Back Style: Zipper Used for one day at a live concert in May. They are still in beautiful condition. I usually wear a larger size (24cm) because I have high arches, wide feet, and bunions, but these are wide, so the M size was fine. Thank you for looking.
