I received these boots on time and immediately took them to the shoe cobbler due to all of the reviews.  I guess I have a little fatter calves then some and with the adjustable strap at the top they were fine.  I had the cobbler stretch the instep and shaft of the boot.  Even after the stretch, the instep is seriously tight and I don't have abnormaly high insteps.  I am hoping with all the wearing of them that I am doing will eventually help ease this a bit. All in all a great boot but only a 4 due to the ridiculously tight instep.
