Definitely recommend following the advice of other reviewers and order 1/2 size up.  I purchased my normal size that I wear for 90% of my shoe needs, and it was simply too tight in the toe box.  Returned for the next size up, and it was comfortable right out of the box as others have mentioned.  Another big plus on day one was that the shoe laces stayed tied all day long with no granny knot, so apparently it is possible to make shoe laces from material that stays tied.  So far, I like the boot very much, but I only have one day on them so far.  I rated the boot a four instead of a five, because the right boot squeaks constantly when walking, which doesn't affect the wear, but I find it annoying!
