I think that KevinR describes it best when he mentions cinching down the boot a bit above the instep (I count about three holes down from the top of the boot) I found that the true anchor point (for me) is the lower 1/3 of the ankle, rather than the top top lace holes/hooks on the boot. It takes a while for me to get the whole thing correct, because if you over-tighten the "anchor point", the foot starts to tingle from lack of circulation.
The whole boot-fit thing is a nightmare to me because I wear a AAA-AAAA, so most of the time I am wearing huge socks + two or three insoles!
