Kenetrek has has been my go-to boot for everything from front- and backcountry patrol to wildfire investigation. They have held up and held strong.
Even when I am on feet all day long, Kenetrek boots maintain comfort and ruggedness that I need. I have four pairs of this brand: Mountain Extreme 400s, Wildland Fire, Guide, and 13-inch pac boots.
The Wildland Fire boots are comfortable heading up and down the mountainside.
In this environment, the world can be unforgiving on your feet. The Mountain Extreme 400s are the best boots I have found for this wild country.
