I was torn between getting these, the DM Case Engineer Boots and the Frye Engineers.  I'm SOO glad I chose these.  They fit perfect, and are so comfortable!  I am on my feet for work all day long, and my feet which usually ache at the end of the day, feel great!  These boots are easy to pull on and look sexier than most other moto styled boots.  These also have a little bit more height than the others, which is always welcome for us shorter gals.  I typically wear an 8.5 US, and sized down to an 8 - glad I did.  Another plus is the rubber soles, which add great traction.
