I should imagine that the best combat boots ever made were made for the US army. I can't imagine how much wear and tear that army boots go through, even on a training exercise. Perhaps you could buy them at an army surplus stores, I'm not too sure.

The best combat boots as far as I am concerned have to be made from all weather leather. They can get soaking wet and shrug off all the water and mud, and they would have to clean up pretty easily too. They wouldn't have laces either if I was buying them, I hate laces as I am always breaking them. I guess Velcro closures don't look that macho though do they?

The best combat boots I ever wore were by Doctor Martens, I really liked the soles on those, they were non-slip and you could stand in anything wearing them - it wouldn't matter, the boots came out looking great and easy to clean too.

There seems to be a bit of a blurred line these days between combat and hiking boots, they look similar but are constructed differently. I wouldn't hike up a mountain in combat boots, so I just hope nobody's going to war in a pair of hiking boots, they'll be looking for a new pair of boots real fast.
