I purchased this a year ago and have used it two or three times. The elastic isn't stretched, and I don't think there's much sign of wear. I usually wear size 24cm shoes, and these fit perfectly, so I think they would fit someone who wears a size 23.5-24cm. I am a non-smoker and I don't have any pets. Thank you for your consideration.
