Danners are among the best I have found. ESP the ones made in USA. Expect to pay from 240-300 bucks. They are very comfortable. Check out Cabelas
Also The Meindl from Cableas
And HH brown are also exceptional. They make the Browning boots like the lightweight ones made out of Kangaroo. These are the ones I wnated to buy for my Elk hunt last year but Cabela's did not have my size.
