La Sportiva Trango Tower Extreme GTX boots: Ideal for ice/mixed climbing and single-day mountaineering

I've had the opportunity to test out the Tower Extremes for several weeks in Alaska and I have been thoroughly impressed. One of the first things I noticed was the enhanced rocker. Compared to other boots I've used lately, the Towers walked like a dream. On vertical ice, they performed exceptionally well and felt light and nimble. In temps ranging from 5F to 32F, I've had toasty feet. I was recently climbing Bridal Veil Falls in Valdez, Alaska, and I kicked through a sheet of ice on a particular belay ledge. About thirty seconds later, I realized I was standing ankle deep in a pool of frigid water. Amazingly, not a drip of water had soaked in. A leather boot would have been frozen solid, but I finished the day with warm, dry feet.
