Aha, got it. You're right, those boots are too long. I would definitely try the 8.5D then. That should put the ball of your foot at the widest part of the boot. The snugness that you feel in the sides with the 9D may be in part because the ball of your foot is not at the widest part of the boot. If 8.5D is in fact too narrow, then try 8.5E. Bear in mind that the first issue does not have to do with length, but rather indicates that the volume/height of your instep is a bit small/low for this boot in 9D. Sizing down should help with both length and instep sizing issues.
Yeah something just didn't feel right...and i couldn't put my finger quite on it until i came across this website. Thanks for the help. I see you recommended an 8.5D over an 8.5E - since i have a narrow foot to begin with do you think an 8.5E would be too wide? I like the snugness in the boots as it is hard to find a boot that fits my foot well but obviously I do not want to cut off circulation either.
