I'm a very very picky girl when it comes to my boots!  My only issue with these has to do with sizing.

THE FOOT BED:  I buy 8.5 for sandals and go with 9's for closed toed shoes.  I've been doing this forever.  I went with the 9 based on other reviews that these were pretty true to size and actually ran narrow (i have ski's for feet, so I was actually looking forward to the narrow width).  I ordered both black and brown.  The brown were huge!  At least an inch of space in the toe box when I tried them on...and that was after a 12 hour shift in the ER.  The width felt nice, but with all that space in front, I found my foot sliding forward, which caused the material at the ankle to pull and wrinkle.  Not cute.  Not to mention, the narrow toe box when paired with a larger size (like a 9) made my foot look very long! (Which it is, but I try to minimize that!).  The toe box also narrows quite a bit as it approaches the tip.  Not sure they'll win any long walk comfort awards, but the rubber grippy sole I'm sure will make them 100% more comfortable and a lot warmer than other thin, hard soled riding boots.  The black size 9's seem to fit pretty well.  I'm going to wear them around the house for a few days for a better assessment.  But the brown ones are definitely getting exchanged for 8.5's.

THE SHAFT:  Although I have skinny feet, I was not blessed with skinny ankles or calves.  Neither do I have a gigantic ankles/calves, but I do often have trouble finding boots that fit my lower leg comfortably.  The widest part of my calf is 15".  These boots were snug, but the buckle at the top cinches the shaft in, and it can be loosened.  So depending on what I wear these with, I will probably use this feature.  I might need to loosen them to get over jeans, but the snug fit is nice with a skirt.

OVERALL:  These boots are very well made.  The leather is super supple, and I foresee them being very warm and comfortable enough (nothing will be as comfortable as my Keen Bern boots...but those look goofy when I try to dress them up!).  So I'm a fan.  Will keep : ).
