I love these boots. They can be worn with skinny jeans or with tights and dresses/skirts and can easily be dressed up or down. I've work them with nice work dresses, sweater dresses, casual t-shirt dresses, etc. - they work with a wide range of styles and are just adorable. On top of that, they're super comfortable. I don't even feel like I'm in heels.
Also, this might be silly to be concerned about, but if you have larger feet the style of these boots makes them look smaller, in my opinion.
