I have this in the Charcoal Grey, though it's a much lighter silver-y grey actually. These are insanely comfy! Mush is right, very step is a cushioned delight! Love that the mush insole has some arch support.  My only gripe, wish it came in half sizes as both my large toes rub against the top of the shoe. Not too badly as the gartered heel does stretch to accommodate my foot when walking. So it lessens the rubbing, hope it stretches out a bit with more use. My feet didn't sweat that much too considering it's a sweltering summer here in Manila. The mesh does the trick here. Now I want the ballet style flats too.
