I'm looking to buy a new pair of hunting boots for my first upcoming Colorado elk hunt. I've researched Kenetrek, Crispi and a few others, but would like some guidance from hunters who have experience. Kenetrek looks like a great option and alot of great reviews, but I've seen some reviews that say leaking is a problem and some difficulty with returning the boots to Kenetrek. Any suggestions? Also, since this hunt is my first elk hunt in the backcountry, should the boots be non-insulated or insulated with 400 grams? Thanks from Nashville
