I bought a pair of Kenetrek extreme hunters, non-insulated, before last elk season. I loved them. Comfortable, great traction, feet never got cold althought they weren't insulated. During chukar season the bottoms of my feet got sore hunting in lava rock all day. I bought a pair of Miendl inserts and it cured that problem.
After probably 200-225 miles, the soles had worn significantly uneven. The outers were twice as worn as the inners. I sent them to Kenetrek for their $150.00 re-soling.
Since it takes 6 weeks to get them returned, I bought a pair of Cabelas boots by Miendl, not exactly sure what model but they are the light weights, maybe Lightweight hunters? Anyways, I got them with 400 grams insulate since I have the uninsulated Kenetreks. First time i wore them the bottoms of my feet got sore so I placed the severly used Miendl inserts from my Kenetreks in them. I hunted 4 1/2 hours Monday in semi rocky country, 5+ hours Tuesday in rocky country and another 6 hours today in extremely rocky country. I'm thinking I like these better then the Kenetreks but after only 20-25 miles on them, I still have to see how they last. In the past I've had to shut it down for a few days when the bottom of my feet get sore chukar hunting. after 3 hunts in the last four days I'm not sure I can get sore in these boots. I was walking across lava flows !/4 of the day today, and really rocky stuff the rest of the day. And I'm going again tomorrow.
Just my opinion but maybe helpful for the next guy.
