I have a pair of Danner pronhorn's that have served me well. I also has two pair of White's boots. The White's boot are far superior to the Danner Pronghorn, but so is there price tag.
White's will make a boot that is custom fit to your foot. White's will also rebuild your boots. The first pair of white's I bought back around 1990. I have sent these boots in twice for a rebuild job and I still own them to this day. These boots are the Smoke jumper model and they are heavy, but they are a great boot.
