Very comfortable, and the walnut brown color should be versatile (can pass for black in a pinch).  These shoes aren't the easiest to get on your foot (this has been the case with my other pair of Rocket Dog ankle boots), but they feel great once they are on.  Comfortable to walk in, and high enough that they keep my foot warm but not stuffy in this in between winter-Spring weather.  A little higher than I really wanted (as pictured, just not what I wanted), so if you were hoping to show some ankle bone, you might opt for a different pair.
