Besides saying that Frye boots and shoes are of the highest quality - these boots specifcally are a great height, supple, and break-in quick. I read mixed reviews on the sizing - and purchased both a 9 and 9 1/2 (I have average width feet, not skinny, and not wide).  I'm normally a straight up 9 in almost all shoes, no matter the style.  It's the case with these boots as well - so I recommend going with your normal shoe size.  These will stretch out a bit overtime - so definitely do not size up.
