I bought nike free flyknit 4.0 black/grey colour, which I thought was unisex, turned out it has womens on the box haha. They look the same as the men s nike free 4.0 flyknit on my eye, but I would like to ask you if there are any difference between the men s and womens versions apart from some of the colours and the sizing which may be a bit different. If they are exactly the same in terms of appearance and dont look like womens shoes, I will not return them back as it is a bit of a hassle. They fit me perfect by the way.
This looks exactly like the on I got, but this is a mens version(I think):
