I've worn these for one season, so I've washed them a few times and they show signs of wear, but there are no noticeable stains. I don't think the soles are very worn down. The straps, etc., may have lost their shape a bit due to washing, but I think they can still be worn. There is a name written on the back of the heel, so I will make it faint before sending. I will also clean the soles a bit more before shipping.
