I've seen several questions and reviews saying it's smaller, bigger etc than expected. If you compare them to other NMDs then they are as expected. I'm a female who wears a 7.5W, the male equivalent according to adidas is a 6.5m. I got the 6M because I believed other reviews. They fit well but if I had 6.5 MI it would be better. If you are concerned about sizing, I recommend going to your local store, trying them on and just ordering whatever size I find comfortable at the store. If you have other NMDs, use their size. And yes they are real, we tested them on arrival, they shine under the sole, we got the expected results. :)
