Just received the dark gray/mango which looks as pictured (more of a blue gray) in fact I didn't even realize the product is described as dark gray until I logged into to complete this review. With that being said this sneaker fits true to size and is maybe a bit narrow as is typical with most Nikes. I have narrow feet, removed the thin insole, added my orthotic and the sneaker fits great. I have not worn this sneaker other than around the house so I can't speak to that but the comfort feels as expected. I wouldn't purchase these for running but for wearing around town, trips to the park with the kids, etc it should be perfect.
I ordered these shoes in grey/green and from the picture, it looks like the shoe is grey and the bottom is a teal green. When I received the shoe, they actually look more of an army green so I'm not sure why they are described as grey.
Being that my son is a Sneakerhead, he has convinced me that Nike is the athletic footwear for the best comfort. And my son was absolutely right! These are very sturdy and comfortable sneakers.
