I am considering the schnees extreme PAC boots. Don't know much about them if someone could lend me some of their knowledge about them that would be great. They are probably what I'm gonna go with. I see that the kenetreks pacs are very similar to the schnees and wondering if they are connected in any way, as in does schnees make them for kenetrek or not? I am wondering if the kenetrek northerns are the same as the schnees extreme?
