If you are looking for a cute pair of flat booties (I am at the moment, which is how I ran into these cuties in the first place), Isabel Marant has a really nice pair out right now, at Net-a-Porter, for instance.
These boots are green-gray as you can see and have nice perforated details, which make them interesting yet very versatile at the same time. I really like these, but grey is not a color that works very well with my wardrobe, I'm afraid. Otherwise I would definitely get these!
