I am so glad I found this boot.  I have a very narrow calf for my height of 5'10" (calf is 14") and a very narrow foot and this boot fit. In fact, it is one of the few boots that actually come in narrow that is stylish.  I normally wear a 10N.  The 10N was a little sloppy so I ordered a 9.5N and it was perfect. The foot was a bit tight at first, but with a couple of wearings, it is now very comfortable. The leather is super nice and it comes out of the box already waterproof.
Also, there is enough room for leggings or skinny jeans without it gapping too much.
So nice to finally find a boot in a true narrow that is also nice looking!
