The belts add an accent and give a slimming effect to the feet.

They've been sitting in a shoe box, and as a result, there are some cracks as shown in the pictures. The cracks are in areas that aren't visible, and the inside is clean. The size is L, and I have wide feet. I usually wear 24.5 cm, and I wear thick socks with boots. By the way, my usual boot size is 25 cm! Thank you for looking.
