Lachy,
be careful buying "hunting boots" from cabelas. There boots are made for short term wearing (the length of the season only) most of their hunting boots are softer than a custard sandwich (like the donut eaters that wear them).
I spent a couple of hours in a shop in the states and walked out with a pair of cableas "mountain hikers" I have found them good and they are goretex lined which is great in the wet.
If you have to get steel caps I'd suggest Taipans if not fork out and buy scarpa's, sounds like you are hard on boots so get the best.
cheers
Hassie
