I have worn J.Crew slippers as long as I can remember, and Piper has officially destroyed my most recent pair (as in they're in the trash). I don't enjoy this new style nearly as much as the last 3 years, but they look super comfy and warm.
I don't have any black riding-esque boots, and fell in love with these at BR this weekend. I love that they're black and brown, and for boots they're extremely reasonably priced. The one issue is that they're technically rain boots and aren't leather (although they look a lot like it). I'm not quite sure how I feel about the rain boot factor, but I might stop to try these on sometime soon.
