A worthy three-season boot: La Sportiva Trango Tower GTX

Considering these boots were designed for three-season use, I was a bit apprehensive about taking them out in August, which is peak summer season in the Colorado Rockies. To my surprise the Gore-Tex membrane did an excellent job at breathing, allowing my feet to remain comfortable while I hiked out in the blistering heat of lower elevations. Likewise, the boot remained warm in the cold mornings at higher elevations, even when I wasn't actively moving around. One morning I spent a few hours photographing time-lapses in a biting September wind at 13,400 feet and experienced no discomfort! After thousands of feet of snow climbing in soft, soggy slush, numerous rainstorms and river crossings, I am confident in the waterproof membrane of these boots.
