Black long boots made of a fabric-like material, with a stylish zipper. - Color: Black - Heel Height: Approximately 12 cm - Design: With zipper - Style: Long boots (knee-high) Thank you for viewing. The material is soft. The heels are quite high, but they don't feel uncomfortable when worn. I used them once, but they were too big for me (I am 23 cm), so they might be suitable for women with feet around 24 cm.
