Just answered that on another thread.
Anyway, I have 'Trecks and Meindl's. I like both. I like the Meindl uppers better than the 'trecks but the 'treck soles have a better grip when sidehilling.
I think the Meindl's provide better ankle support and both are equally warm with their 'thinsulate' linings.
I use 'treck footbeds exclusively. The Meindl footbeds aren't as good as the Kennetreck footbeds IMO. However, I change mine out every year.
One thing about the Meindl's that I found disconcerting is, they come in greenish tone new but as soon as you apply boot conditioner (I use the Kennetrek brand), they turn dark brown.... no biggie but odd.
It's a personal toss up actually. I got the Meindl's first because I like to try on a high end boot to make sure it fits right and I could do that with the Meindl's (at Cabelas). I had to mail order the trecks but they (luckily) came in the right size and width. Not a fan of shoes/boots by mail actually.
I think they are both good boots. My big issue with any boot is I don't want to 'break in' a boot at the expensive of my feet prior to a hunt. neither the trecks or the Meindl's need to be 'broken in'.
Don't know anything about the 'Crispi Critters'....lol
