The boots are very comfortable around the feet and calves.  In fact they are the most comfortable shoe/boots I think I have ever placed my feet in.
One problem, they killed my ankles.  The fabric is supper tough and not flexible around the ankles.  I've worn them hunting for over 12 miles now and they have not broken in around the ankles.  I actually had a fall because the fabric would not let my ankles bend enough going down hill.  I will wear them some more and and see if they break in.  On flat ground they are great.  In mountain/rocky areas the are tough on the ankles and can cause safety concerns.
Traction is great!
By the way, they are very waterproof!!!!  It was in a rain forest, and boy did they hold up.  Rained the entire time.  Everything was wet but my feet!  The next day I could not wear them due to how sore my ankles were and I ended up having to wear a pair of high end hunting rain boots.  Since my feet couldn't breath they were drenched from sweat at the end of the day.  So for water proof these boots are great.
Once they break in, I might change my review, but I cant see giving them a real high rating due to how hard they are on the ankles...
