Both pairs of Kenetrek boots I have had were very comfortable. However, the leather rotted out quickly on both pairs. They lasted less than half as long as Vasque, White’s, Frank’s, Crispi, Schnee’s, and Lowa that I have used.
I always used the Outdoor Research ones until this fall. I tried the Kuiu Yukons this fall. I don’t think they’re as durable as the OR ones, but they are much quieter.
