BEST FOR: Ice climbing

The Trango Tower Extreme GTX is the latest offering in La Sportiva’s popular Trango line of alpine boots. With a bit more insulation than the Trango Ice Cube boot, it’s slightly beefier and slightly warmer. At 26 ounces per boot, it’s also heavier than the Ice Cube by an ounce or two, but also kept my toes warmer on cold days.

The Trango Tower Extreme GTX lacks the Trango Ice Cube’s built-in gaiter, but I didn’t miss it. The boot top has a stretchy elastic around the perimeter which protects against snow entering; it works OK for moderate approaches and technical climbing, but if post holing through deep snow I would don a gaiter.

The boot is similar in width to the Ice Cube, i.e. medium to narrow, but the interior is higher volume overall. I have a relatively low volume foot for a size 13 street shoe (I wore a Euro size 46 in these test versions), and I found my heels rising more than in the Ice Cube, even with an extra insole added. That said, people with higher volume feet will relish the extra room for a thick sock on cold days.

The boot sole is stiff, welcome during long ice pitches; yet I also hiked miles in these boots right out of the box with no blisters or heel rubbing. The uppers are flexible for side stepping and hiking. You sacrifice some support for front-pointing, but overall the boot strikes a nice all-around balance.

With its extra warmth and durable synthetic construction, the Trango Tower Extreme GTX is a strong contender for steep ice routes and multi-day mountaineering trips in warmer conditions.

Rock and Ice vigorously tests all gear it reviews for either 50 days or 50 pitches. This is a time-consuming process and limits the amount of new equipment we can present to our readers. Every year hundreds of new products hit store shelves, and most of these aren’t reviewed due to our stringent selection and review process. To better keep you more up to date on what is new, we present First Look. Gear in First Look has not always been field tested, but is gear we think you’d like to know about as soon as it is available. Some of the gear will be reviewed using our 50 days/50 pitches criteria, in future print and online editions of Rock and Ice. We have opted to use affiliate links in our gear reviews. Every time you buy something after clicking on links in our gear articles you’re helping support our magazine.
