Her boots are by Isabel Marant. Lohan is wearing them too in the Fashion section. It's what I notice on the streets all the time. Mostly (thank God) older teens and twenty-somethings are the one's sporting them. I see them with summer dresses and sometimes shorts.
I've seen my share of trends and the one's that make it to street wear usually aren't too bad. In the 90's we'd wear black booties with black opaque stockings and it made for a nice silhouette. These boots do nothing for the look of the leg and make me think the girl has dirty feet and smelly boots.
