authentic and practically brand new. patent black leather (Perfect Black). size 12 in women's but if you know anything about miller sandals then you know they run small! i am a size 11 and wore these. paid $200 new from nordstrom and wore them once on vacation so they've been sitting on the shelf ever since. Ships same day for orders placed before 4pm CST! I do not have the original box but I have the dust bag I can throw in.
