Alright boys here is my experience with my Mountian Extreme Non-Insulated keneys...
I got a pair last summer (2010). I DID put one coat of the Kenetrek boot protectant to help repel water, and I did take very good care of them. I used them on 6 hikes, 6 shed hunting trips, 7 days of fieldwork, and 3-4 days of hunting muleys on the extended Wasatch (snow and cold). In my opionion, they were extremely comfortable and I loved the stiff soles for the rocky terrain.
During this time, there were several days when I was hiking in snow all day, as well as wading in creeks (ankle deep)soaking the boots and my feet never felt a drop of moisture...until I did it for consecutive days. I started to notice a small amount of moister and it only got worse from there. (I would let them dry out between use)it finally got to the point that my feet would be soaked within an hour of even walking in tall dew covered grass.
I was so pissed that they were leaking after that kind of an investment I called the customer support line and they had me send them back for testing. I received an email letting me know that they had done a leak test on them and sure enough... they were leaking.
One week later, I received a brand new 2011 pair of with no cost to me. I can say that they have great customer service and stand behind their products. But, i do think they need more testing on the membrane material, or they need to work with the Gortex brand material. If they could get this issue worked out, i would say they are the best possible boots.
