I received these as a gift about 5 years ago, but I've only worn them about 3 times. There's some soiling on the opening from rubbing against socks, but overall, I don't think they show much wear. Please refrain from purchasing if you are concerned, as they are not brand new. I have stored them in a shoe box the whole time. My foot size is 23.5cm, but they fit perfectly when I wear socks.
