I'm selling these shoes because I bought them new in size 39 (24.5cm), but they were too tight and difficult to wear. I think they would fit someone who wears 24cm more comfortably. I only tried them on indoors, and haven't worn them outside. Please consider that these are used items. I have a cat. I take great care to remove any cat hair, but please refrain from purchasing if you have allergies or are concerned about this.
