I've been on the hunt for a good, quality pair of flat brown boots for some time, and haven't found many without too much detailing or heel. Maybe I'm looking in all the wrong places? Most of the above are an investment, but they're the best I've found or tried by far!
I finally went with the madewell boot during a generous sale (I like their shape and fitted top, and plan to have these for quite awhile), but jcrew's were a close second and are majorly on sale through this weekend. Hope you have a good one!
