Why We Like The Trango Tech GTX Mountaineering Boot

The La Sportiva Trango Tech GTX Mountaineering Boot bridges the gap between both backpacking and mountaineering for an option that helps us confidently tackle all types of terrain. We appreciate how its low-profile sole and midsole allow technical footwork and edging capability when climbing easier graded routes, while also offering semi-automatic crampon compatibility for glacier travel. The waterproof upper and GORE-TEX membrane keep your feet dry across mountainous terrain, and the gusset-free tongue construction increases comfort for long miles on the trail.


  • Boot that's equally suited for both backpacking and mountaineering
  • GORE-TEX membrane blocks moisture and allows vapor to escape
  • Gusset free tongue adds comfort during long miles
  • 3D Flex system offers precise support across rough terrain types
  • Low profile midsole and outsole enable technical foot work
  • Vibram CUBE soles offer edging capability and enhanced traction
  • Impact Brake System makes strenuous descents more comfortable
  • To-the-toe lacing system offers a precise fit for enhanced control

Nice boots but terrible fit.

Sadly the fit in the toe box is smaller than other boots from them. So much so that after one hike i'm looking at serious little toe blisters on each foot. Normally I wear a 12 in La Sportiva and have had great success with their other boots with little or no break-in needed. Another size bigger they will be too wide i think. Becides the fit, the construction of these looks very good. Too bad, won't be wearing them again.

Durability and Traction.

Very durable and well-made boot. I own two pairs (47.5 and 48). I have 400 miles on 1st pair and opted to size up to a 48 (300 miles on them so far). They are holding up very well. I find they breath well and the traction is exceptional. Most mileage has been in the San Juan Mountains of SW Colorado and the Colorado Front Range with sharp granite terrain. The soles also grip well on slick rock. They also breath well and are great for tramping through bogs / low water / morning dew. My only complaint is with the toe box - just wish it was a tad roomier and there was a 48.5 size. I normally wear between a US 13.5 and 14, and I use full sole orthotic. The 47.5s were a bit too tight, but not painful. I then bought a 48, but still need more width in the toe box.

Great FL Boot for the PNW

I've put it through the wringer
Size Bought:
6' 2"

Just summitted Rainier with this boot and it was a game changer. Way more comfortable than trying to be fast & light with a traditional mountaineering boot. On another mountain I was able to comfortably run down the approach with these bad boys. Seem to work great so far on mountains with long approaches where you still need crampon compatibility and the freezing level isn't super low (I can imagine feet getting cold in prime winter conditions with these). I would defininetely get another pair.

Good boots for mountaineering

I wore these for a Mount Rainier summit and they worked perfectly. They didn't have much of a break in period for me, they kept my feet warm in 20 degree farhenheit weather and my feet didn't get too hot while wearing them in 60 degrees. The fit was good, they felt light on my feet without the crampons, and did great while descending on ice/slush/mud. I haven't truly tested their durability yet but initial impressions are good.

Four Days in the Wilderness: Torn and Frayed

The Trango Tech GTX make for a worthy choice for busting out long trail and backpacking excursions in the North American wilderness. But throw boulder fields, steep scree, talus, and a few mellow pitches of class 5 rock into the mix, and these boots are likely to tear at the sidewalls. That is a complete bummer, because every other part of the Trango Tech lives up to the La Sportiva record of excellence. One short backyard test with crampons proves they hold steady, but under most conditions they will not last more than one long day on glaciers because of the lackluster sidewall material. These synthetic boots should have the same rubber side-wrap found on the leather version. The pictures here show results of only four travel days off-trail and above treeline in Wyoming granite and quartzite mountain ranges.

Good support, good grip, poor durability

I've put it through the wringer
Size Bought:
5' 11"

Have about 125 miles of mixed trips with these--heavy snow, easy Sierra summer backpacking, and tougher off-route scrambles. They broke in OK--took about six days of hiking before they were good to go, and even still I use some KT tape on my ankles to avoid hotspots...but they are comfortable for super long days (18+ hrs hiking) and quite light for the support and relative weather resistance. My only issue with them, but it's a big one, is I'm not sure I'll get more than two seasons out of them. It might have been chafing from wearing them with snowshoes but the sides are wearing through on both boots, and in general these look like three year old boots, not six months. Still comfy though so I'm hoping to wear them until the side gives out further, at which point I'll probably replace them with the full leather version assuming they fit the same.

So far so good.

I've used it several times
Size Bought:

I bought these boots to bridge the gap between mountaineering and hiking boots so I could use them for hiking on trails to mountain summits. So far these have lived up to the task. I never got blisters or any other comfort issues. They were a little weird to get used to walking in at first but that was overcome quickly. This was probably due to the fact I have never had a mountaineering boot before these. The only gripe I have about them is when the inside fabric by the ankle of the boot gets wet it seems to take longer to dry out than most footwear I have had in the past. If you have a boot dryer then no problem but when backpacking for days or weeks at a time this would be an issue especially in higher altitude, colder conditions. However, these will get their first real test as I utilize them on my backpacking trip in the Sangre De Cristos in September. Will update my review then.

Bad fit

I've used it several times
Size Bought:
5' 11"

The good: Well made, stiff, and super grippy. The bad: The fit is bizarre. I?ve tried to break these guys in for a long time to no avail. I?ve owned them for a year and they still give me extremely bad blisters in the heels. This would indicate they are sized too big, but that said, they feel extremely tight on the top of the toe box making them feel too small even though I have room in front of my toes. Theoretically, they are exactly my size. Long story short, I can?t tell if they are too big or too small. I?ve never had this issue with other Sportiva products. I thought they?d break in better but they haven?t. It?s too late for me to return them, otherwise I would. I may try to sell them elsewhere but I would seriously recommend getting a few sizes to really nail it.

I have had these for seven months, and have mostly used them for day hikes and walking around the city. I loved the fit and how comfortable they are. Unfortunately, the waterproof fabric where the toe creases has started to leak. And, after a very small amount of climbing up some steep rocks in Arizona, both soles developed major cracks! These are advertised as mountaineering boots, but are too fragile for that kind of use.
