I'm on the hunt for a pair of quality boots in MN too. So far I've been to
Scheels in Eden Prairie (had a few Crispis and Kenetreks, options were very limited due to their stock in size 12). I've heard great things about their customer service.
Cabela's in Rogers had Zamberlan's and I think...
I've been eyeing these up too. It would be great if a store near me had them in stock but it seems like even most online retailers are out of stock. Did they just make a small 1st run to see how they would sell?
My wife and I are from MN. We flew out there last year and it was an amazingly fun time. Unfortunately we aren't going to make any TAC events this year.
