Trango Cube GTX Mountaineering Boot

Winner of the Gear Institute's Best New Gear award at the Outdoor Retailers Summer show,  the all-new, incredibly light La Sportiva Men's Trango Cube GTX Mountaineering Boot makes your extreme high-altitude pursuits heavenly. The GORE-TEX insert ensures that water won't slip into the boot and tank your toes midway towards the apex of Gannett Peak, and part of the tongue comes out when you need more room for your foot. Direct-inject lacing system and an exclusive Vibram sole lightens your load so you can pack an extra chocolate bar (or 6) to celebrate the summit.

Put together without seams, the uppers blend waterproof QB3 and FlexTec 2 fabrics to keep external water away from your toes. A rugged Vibram rubber rand protects your toes, wards off water, and rounds out this stable shoe when the trail takes a new twist on technical. The direct-inject Thermo-Tech TPU lacing system keeps seams at bay for extended durability while shaving off nearly 1/3 of the weight of traditional riveted lacing systems. GORE-TEX Performance Comfort lining guarantees a waterproof, breathable climate-controlled environment for your foot whether you're learning to self-arrest on ice or starting out well below the snow line.

A low-profile 4mm graded nylon insole puts a skinny pillow under your heel and has a barely-there feel by the time it reaches your toes. A combination of materials create a stable platform for hiking without taking away underfoot cushioning. Opposing lugs of the Impact Brake System offer traction for the trek up and trip down. ONE, an exclusive sole made by Vibram for La Sportiva, keeps the weight off and the silhouette on the down-low. The TPU heel insert allows the Trango take a hybrid crampon for quick changes to accommodate the hyper-variable environment.

  • Ultralight mountaineering boot for summertime alpinism
  • GORE-TEX Performance Comfort is waterproof and incredibly breathable
  • Upper composed of Flex Tec fabric and Vibram rubber rands
  • Removable tongue helps the boot dry faster
  • Nylon footbed offers a stiff platform for stable support
  • TPU heel insert allows hybrid crampon compatibility
  • Vibram One sole designed exclusively for La Sportiva

Good all around boots

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 43.5

I bought these for high snowy passes on long trips this summer, but just got my first day hike in with them. I was concerned they wouldn't be comfortable for hiking, but they were great right out of the box. The soles are as stiff as I like hiking boots, which is very stiff for hiking, but the uppers are supple. The fit is snug but not too snug - my feet are narrow and slender. I bought a 43.5 and I nearly always fit a size 10 in any brand. I was on not steep snow for some time but the day was warm and my feet stayed very warm. I'll say more when I've actually put them to work.

Update - a few months later and I have taken them on long hikes with a backpack, and steep summer snow off trail in the Tetons with crampons. They've been great the whole way. However they're not as comfortable for hiking as my trail shoes and I wouldn't use them for that if I didn't expect snow.

Great boots

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: 44

I have put many miles on my boots in rough country while hunting and packing heavy loads and mountain climbing the highest peaks in Washington state. I've used them in a full range of weather from 70-10 degrees and rain to snow. I have not had a single blister or even a hot spot. They work great with my crampons and provide good support for glacier travel and traversing scree slopes. Of note, they were a full size small and I had to exchange up for a good fit. These are great boots!

Hi, I just bought a pair and am wondering what crampons you used? Thanks!

Great boots

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: 65

Purchased these boots in highlander (camo), for my chukar hunting obsession. Quality is incredibly high in the materials used. The comfort and fit was spot on for my long narrow foot. The laces really lock your foot into the boot. Sidehilling doesn't cause foot torque. And there has been zero hotspots after 12+ miles in some really steep rocky stuff.

took my time to review

  • Size Bought: 43

I have had these boots for over two years now. I have put many a mile on these in just about any condition you can imagine. They have held up extremely well. The rubber on the toe is starting to show some wear and peeling but for the miles i have put on them I am not at all surprised. I would buy them again in a heartbeat.

Poor Quality

  • Size Bought: 41.5

I bought the boots in August 2018 and used them just once. They were kept on the shell in my garage. By Nov one of the boot's heal started splitting. I contacted Backcountry because the boots were still under warrantee. I was advised to provide evidence which I did. I mailed the pair back and received a new pair. I appreciated Backcountry's service. I strongly believe the new pair will have similar problem. I probably will not file for warrantee again if it happens again. La Sportiva make good 4 season full leather boots. I bought my La Sportiva Napal Cube prior to this pair, used them a lot, and they show no sign of splitting. BTW, my wife's La Sportiva Trango Tower GTX are also showing sign of heal slitting after one moderate use (very much brand new). If you have other choices, please don't waste your money until La Sportiva correct the problem!

Best Moutaineering Boot!

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size

This was the best mountaineering boot option for my brother-in-law who is travelling to Switzerland this summer and climbing the Matterhorn. After researching all options in the category, this is going to give you (and your feet) the best mountaineering experience, especially in that area of the world in the summer months. Look no further, you have arrived.

From Tahoe to the Altiplano - Phenomenal

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 42

I have a narrower fit, and the 42's fit splendidly with the right amount of room in the toe box. They arrived practically broken in, and after owning them for a year, they have been my go-to for any activity needing a hiking boot. While they are not insulated or full-shank, they were perfect for getting to high camp at Huayna Potosi at around 17,000 feet, and for all the activities on the Bolivian altiplano. Basically, other than ice climbing and more than

moderate glacier travel, you are good to go. They weigh less than most traditional boots with more functionality. Highly recommend!

From Tahoe to the Altiplano - Phenomenal

Very Decent

  • Familiarity: I've used it several times
  • Fit: True to size

I ordered a ½ size larger to possibly accommodate a lager sock for colder weather. When the boot arrived, I was worried since the shoe fit tight and I thought I did not order the right size. I wore the around for a while and my foot did not lose circulation.I was pleasantly surprised on many levels. First, the fit was great. It was probably a good decision to go that ½ size up but going to high would ruin the rock climbing feel. The boot is plenty warm for summer, cold climbing. First day using the boot was snowing on the glacier with strong winds and my feet were warm and dry. The next day we climbed a snow and rock arête up to 5.8 and the boot worked great on slap (very good friction with rubber) and steep faces (great edging abilities). I was able to put on the crampons fast and with ease. I did not experience any hot spots at all. That was great since, I have old leathers that still give me problems. Both ways, and I did not have to worry about the boot being new and not broken in at all. I want to give a negative view but I did not experience one but I only used it for three weeks. I have been pushing away buying modern boot, since I have been happy with my old leathers. But this boot was way lighter than my leathers and climbing rock and the same high grade. I am glad I spent the money, which I don’t always like doing.

La sportiva/Backcountry customer service

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 43

Being a faithful La Sportiva user I was excited about getting these as they are heavier than most of my La Sportiva shoes / boots. I have had them for a few weeks now, and have probably put 40 or 50 miles on them. All light-duty walking thus far because of the weather in Montana right now and the large amount of snow on the ground. All day comfort, and my feet have not gotten cold in them yet. Even short trips outside below zero. The soles have excellent grip on slippery surfaces like ice and snow. Speaking briefly on the service from backcountry. My original order which had been placed a day before my girlfriend ordered a pair for her, got delayed due to the pre-Christmas Rush. Customer service set up a free Next Day Air delivery for a second pair. I received these very expediently and recently had to return the other pair that that arrived on the next Monday. Kudos to Backcountry for customer service above and beyond. In summary I am very satisfied with everything pertaining to this recent order.

Good Boot but Short Length-Wise

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: 45

I'm a 11 street shoe, 11.5 running shoe. I went with a size 45 which according to La Sportiva's shoe chart that should be the equivalent of a 11.25 size. The width was a little too snug at first but after breaking them in it is exactly where I want it for a technical rock boot. The instep is shallow though after using superfeet green insoles. The biggest issue I have with this boot is the length. It actually comes up shorter than my size 11 Asolo hiking boots and size 11 Tennies (the irony, a mountaineering boot that has a more precise fit than approach shoes). The difference in length isn't too big but on steep descents I fear for my toes and I wouldn't dare climb ice in them. I don't know if going up to a 45.5 is a wise idea because the width fit would become sloppy and I lose my edging.

I wish La Sportiva was a little better at their sizing.

Best Boot ever!

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 12.5

The fit of these boots is flat out remarkable. I 'm a 12 in running shoes and a 45/46 in climbing shoes; I bought a half bigger to wear 2 pair of thick wool socks. No blisters at all, not even a hot spot. My foot is average across the ball and a bit narrow in the heel. I walked them in the foothills for five or six days being aware of normal foot problems with new boots... there were None... I've been climbing for over 50 years and have had access to the best climbing gear out there; La Sportiva has out done them self's with this boot. Up hill with weight (50/55 lbs) my feet were happy, kicking secure steps in Sierra cement for clients easy, post holing ( with gaitors ) a grunt, yet compacting and producing an edge under the surface to stand up on was easier with the sharp edge of these wonders... Plunge stepping down ,I felt under full control as I did long ago in Super Guides or Makalu Doubles. They are so light, it's almost like I'm wearing a trail running shoe, so connected and with persuasion edging. On to rock, 5.6/5.7 is fun on the tips... I'm old school, so, edging comes naturally to me as with Kronhofers or Spiders; not super stiff though, the rocker across the ball of the foot is on a slight diagonal which presents a very natural feeling foot fall .
I can't say enough about these boots, totally water proof, the lacing is simple and quick; there is a lock on the lace at the ankle that allows for exacting tension. It does require a bit of break in above the ankles, so start off lacing lower at first... I've put at least 65 to 75 miles on them and gone from 9000 to 13500 four or five times in the last month; my feet are the happiest they ever been.
Blizzards in May and post holing in June, a crazy start to the Sierra season; I'm enjoying our mountains to the fullest because of these boot! Really, I'm not kiddin".

Light, fast, versatile

  • Size Bought: 45.5

I have used the Trango Cube GTXs for a week in the Boston Basin in WA, climbing WA Pass, mixed climbing for several days in the Wasatch, and a week on the highest volcanoes in Ecuador. I love these boots, and they are solid trekking fast, slogging through the mud in WA after endless days of rain, mixed climbing with BD Sabretooth crampons, or many climbs on 5.7+ rock. I have not had them sustained low temps without high activity, but I wear them every time I can if I don't think I need more protection from pretty cold temps.
