Simple black over-the-knee sock boots Size 23cm - Color: Black - Size: 36 (23cm) - Heel height: Approximately 4.5cm - Total length (laid flat): 50cm (These are sock boots, so they stretch quite a bit ✨) I am 150cm tall and usually wear 22.5cm, but the size was perfect. I wore them over tights, so they haven't touched my skin directly. I'm selling them because the low heel made them difficult to walk in. Thank you for looking.
