Hello Rick,
I am a fellow weak ankle guy and consider my footwear by far to be the most important piece of my equipment when I travel to hunt. I am so paranoid about losing my boots when flying to Africa that I normally wear them.
The boots I have settled on at Russell Moccasons, in the Joe's PH style. I find them sufficiently ankle stabilizing and at the same time fairly lightweight. Of course this is for hunting dry warm climates. I have not tried their other styles of footwear.
