Going into brush or suspect country why don't more people wear at least leggings. They cost little and then there is the Mil surplus hard plastic leggings.
I shopped last fall for snakeboots and they have some nice and light 16 to 18 inch high models in stylish camo, at Cabelas, Bass Pro and Sportsman Warehouse.
I have seen some stylish high boots for women and men of the type before they developed cowboy boots with a lining, forgotten the name, that will stop any snake if it get through the leather. One pai I saw, at some time, in Cowboys and Indians mag were 450 to as high as you wont to go on style and leather.
