These were gifted to me with no box. If inauthentic, I surely can't tell, and I have several pair of Yeezy 350's. However- full disclosure- I have no original box. No proof of authenticity, BUT if they are not, then they could fool me. I just don't wear them. Never had them on outside. Here's the deal: look at pics closely 10000000% worth what I'm asking. Save the unnecessary comments and chatter. Price speaks for itself! Buy cheap and enjoy.
