I've had 3x Kennetreks, 2xSalomons, 4xCrispi, 2xLowa, Zamberlan, Danner, Keen etc.
I live in the southwest, so cold is not an issue. After trying them all I prefer the Crispis for my needs. They are very comfortable to me and great all around boots. I've always preferred the Nevada's.
The pairs of Kennetreks I have owned have also been great boots, just a bit rigid for me. If I were going up into big mountains, as in Idaho or Alaska or whatever, I would probably enjoy them much more than I do down here in our lower Rocky Mtns and one the desert hills. My kids used to call the Kennetreks my storm trooper boots cause they were so stiff. They hold water pretty well too, if you have to cross a River the hard way
I do buy the Kennetrek seal/wax and keep all of my boots lubed up with it at least once or twice a year.
Lowa renegades are great on the feet, but I've had two pairs where the side stitching separated on the edges where they articulate. Frustrating, but not hard to fix.
Good boots are a blessing when you're hunting or hiking. Keep your feet in good shape and you'll hunt longer and harder.
I catch heck for it, but I have been known to get a pedicure or two during the fall and it sure helps my feet out a lot. There's even a picture floating around of me asleep in the pedicure chair with a Coors Light in my hand and a steamed towel wrapped around my face while my feet were soaking in some juice concauction that looked like a pineapple margarita. Sometimes they even do a ziplock bag full of hot parafin fun wax on each foot and they squeeze it In between my toes, then when it sets up they peel it off. That's what I get for going to a salon owned by my wife's friends, I show up with a 6 pack and a couple bottles of wine in the late afternoon and become the entertainment for the day. Haha its a little awkward but so worth it.
