I am purchasing a pair of boots this weekend. I am looking at non insulated and leaning on leather because I will be using them from August thru November in Colorado. That being said two of the pairs I am looking at are a mixture of leather and cordura. I am 6'1" and 185 lbs. My feet are narrow to medium width with a higher arch. I am looking at the Cabela's Denali by Meindl, Hanwag Mountain Light GTX, Lowa Ranger High GTX, and the Crispi Idaho. All are about the same cost between 280.00 and 320.00 because of coupons and shipping. I would like to know which is the best for my type of feet as well as elevations between 9,000 and 12,000 feet. Thanks in advance. This is my first expensive pair of boots. I have always bought Danner's and want to upgrade.
