These are brand new and authentic. They were given to me as a marriage gift. I have never worn them hoping that they'd be worth more one day. However, given the recent events surrounding Kanye West, I think it's safe to say that the value will more than likely not go above the market price. With this being said...These were over 500 hundred dollars if I remember correctly and although I no longer have the box (trashed while moving) I am asking no less than 180 for these.
