I took an chance and purchased these online without having tried them on. I wear between a 11M-12M and decided to go with the 12M.  I couldn't be happier with my purchase! These boots fit like a dream! The toe box is roomy and rounded. The shaft is wide enough to fit regular jeans inside them, but not so wide that you can't cover the boot. I found the ankle a little baggy on me but my ankles are very slim for my size/height. I'm 5'10" and the shaft hits about three inches below my knee. The sole itself is nicely padded inside and very flexible. The Moss colour looks like a rich chocolate brown, and the quality of the leather and the workmanship is superb.  I would highly recommend these boots!
