I bought these three years ago and used them once a week for three months. I recently washed them with detergent, and some black dye has transferred to the bottom of the heel area. I think it will probably come clean if I wash it again with detergent. Other than that, I think they are in relatively good condition. They can still be used, so if you want them, please do! I usually wear 23.5 cm, but these fit perfectly at 23 cm, perhaps because they run a bit large. Price is not negotiable.
