I received two pairs of the "grey leather" desert boots, one from my original order and one as a replacement.  Both pairs were actually dark brown and bore no resemblance to the images.  Weirdly, the alternative leather laces included with both pairs appeared to be grey and did not match the leather used on the boots themselves.  My bet is that the manufacturer mistakenly created a batch of "grey leather" boots using a dark brown leather.  Oops, I suppose, but don't order these.
