I'm 8.5 on the brannock. I fall between 2E and 3E on my circumference according to JKs chart at size 7.5 (one size down per reccomend). 7.5 gives me a thumbs width between the tip of my toe and the front of the boot, also per reccomend. A 2E without any insole feels perfect. 2E with insole feels a little uncomfortable. So I ordered 3E with expectations to keep the insole in. For me, it seems that adding their insole gives the effect of decreasing the width by one size. They fit great around my heel, great around my ankles (after the first 60 hours), all the way to the ***** of my feet and then my toes have all the room in the world. You're feet cannot slip to the front in these boots if you have the laces tied.

I ordered a second pair in 2E, with expectations to use no insoles this time.
