Since we have a subject on a hiking shoe, lets start one on a battle boot.
I use different boots for different tasks, e.g. hunting, combat, everyday, etc and have several pair in each category. Some of which are cross over boots which helps to keep costs down.
With that written, my favorite pair of boots for hunting that cross over well to training are my Filson boots. Yes they are expensive BUT they are 100% guaranteed over the life of the owner.
My second favorite are my Converse Patriot series with steel toe. These are starting to fall apart and I have probably one more season till they end up in the trash.
The Patriot series are not available anymore so I need a new boot to try out. What are your favorite battle/training boot?
