I waited several months to rate these boots because I wanted to subject them to the full range of conditions I work in.  The boots were comfortable right out of the box.  With a few months wear they have only improved.  I have worn them in mud, snow, desert heat, over rocks, through sand and water.  I have even worn them lifting weights and working out with kettlebells.  There are no signs of wear and the boots simply become more and more comfortable.

My Danner boots are worth every penny I paid for them!
