Heel approximately 10cm, total length 43cm from the floor. Opening circumference 17cm. Used once, as shown in the photos, there are some scuffs on the heel. Size 24cm. I usually wear 24.5cm, but these fit. Inner zipper. I bought these to match a bag, but I no longer use them, so I'm also selling the boots. As I prefer to remain anonymous, returns due to size differences or different from the image are not accepted. Thank you for your understanding.
