I purchased these from the Ifme official website and used them for about six months. There are scuffs and stains that won't come off even after washing. I think they are still usable. The insoles are originally different colors for left and right. I have written my name on them, so I have attached a tag-peta label. I have hand-washed them before listing, so you can use them right away. Please consider these if you don't mind them being used. Size: 17cm and up
