These are short boots from Nano Universe. They are size 37, which is 23.5cm. The heel is 4cm high and the color is brown. I wore them with care for one season. There is some peeling on the toes, but there are no other noticeable scratches or stains, and the heels are only slightly worn down, so I think they can still be worn. The thick heel provides stability, and the 4cm height makes them comfortable to wear, which I liked. They have a zipper on the inside, making them easy to take on and off.
