A smart choice for serious climbers.

Footwear can mean the difference between success and failure in the mountains, so count on the La Sportiva Trango Extreme EVO Light GTX Boots for fast-and-light alpine climbs and massive ice lines. The Gore-Tex Duratherm lining ensures warm and dry feet even when you're sending a dripping ice pitch. La Sportiva used a combination of Cordura uppers and Vibram rubber rands to make these boots tough enough for life in the alpine realm, and the narrow-profile, crampon-compatible Vibram soles give you stability on and off the ice.

La Sportiva Trango Best boot on market

  • Familiarity:I've put it through the wringer
  • Fit:True to size
  • Height: 6'5"
    Weight: 270 lbs
    Size Purchased: 46.5

La Sportiva has always been a leader in outdoor sporting goods. Now with the Trango it puts the competition to rest for three reasons. Firstly the weight, the sleek design and light weight make this boot great for comfortable long days without sacrificing durability. secondly the comfort of the boot is by far the best on the market, whether hiking, multi pitch or single it stands up to everything easily. And lastly price. priced cheaper and competitive with it makes it the go to boot for experience or novices to ice climbing or alpinism.

Are you going to have size 43-44 anytime soon?


Really wanted to love these, but...

  • Familiarity:I returned this product before using it
  • Fit:Runs small
  • Height: 6'1"
    Weight: 185 lbs
    Size Purchased: 46 and 46.5 (normally 11.5)

They just didn't fit right. I've been looking for just the right mountaineering boot to climb Rainier and also use for general backpacking. I went to the REI flagship store in Seattle and tried on multiple brands - La Sportiva, Salewa, Scarpa - and I also bought some Asolo's (which is what I wear for hiking boots) online. I typically wear size 11.5 shoes, which is also what I wear for Asolo hiking boots, and my foot is on the narrow side, though I typically get normal width footwear. At REI I found that the scarpa's are generally to wide for me. When I get the length right, there's too much open volume in the forefoot. Salewa didn't fit me quite right either. The La Sportiva Trango Cube GTX fit me great - though of note it was a 46.5 (US 12.5) that fit - a full size larger than normal. The Asolo's I got also fit well, though both the Trango GTX and Asolo didn't have insulation, which I want since my feet do generally tend to get cold (and I'm from Minnesota so I have experience with this!). I decided to give the Trango Extremes a try. First I ordered the 46.5 but they ended up not fitting quite right so I tried 46 as well. The length in 46 was good, but I had to really tie them tight to keep my foot secure - which resulted in a couple pressure spots that I couldn't relieve because the lacing system does not give much option for tailoring tightness in different areas of the foot (which Asolo's do really well). I tried walking around in them for a few hours - I really wanted to love them! - but they just didn't feel right and I've still got a couple sore spots 24 hours later. They also were a little heavier and bulkier than I expected - though the insulation likely played a part in that. The boot looks great and I could tell it's great quality, but for the price it needs to feel and function great. Unfortunately this one didn't work for me.

Hi! I will climb some Mountains in Patagônia next summer, some of them with 4000 meters. I will do some long approuches, rock and ice climbings! I am sure That it will not be too cold so I am not sure if I buy the trango extreme or the trango cube?

If you're going to be mostly on glaciers and snow the Cube is better suited. But if you're going to be doing more "rock" climbing and approaching the Trango. They hike better and have more flexibility in the ankle which is great for edging on rock.

Thanks a lot Reid! I am afraid that the Trango Cube could be a litle bit cold, what do You think about that?

The Trango cubes could be. I haven't used those yet. But the Evo extreme is much warmer than other boots I've used. Mammut Monoliths, LS Karakoram, LS Trango S.

The Nepal Evo and Spantik are much warmer but do not have the same dexterity

I have outgrown my Trango S and was looking...

I have outgrown my Trango S and was looking to upgrade to the extreme but wondered how the sizes transferred. I wore a 45 in the Trango S and was looking to go to possibly a 46 in the Extremes, anyone have any input or advice?

Rep just said it should be the same size. I would go with the 45's to start. If they dont work we can always set you up with an exchange.


Fit me like a glove, or better?

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

These boots could not fit my foot any better. I have not had a change to really test them on anything steep, but my less technical trip have been a dream for my feet. On one certain occasion the only part of me that was not soaked to the core was my feet in these boots. I will continue to buy these if they ever wear out.



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

Warm, Great Quality, but very painful. I walked around for over a month trying to break these boots in, but no luck so far. When I walk more that 200ft or so, a sharp pain shoots up my fibula, in each left and right leg. I bought a size large than I normally wear to account for thick socks. I'm trying out different insoles now to see if something will help.

These are really great boots, especially with a good set of crampons, so I'm hopeful that I can still make them work somehow. I'll come back and edit / add a photo to this post if I find something that fixes the problem. I bought 4 different insoles... something better work.

Not sure if it will help but I needed a size and a half larger. I am an 11 and finally fit into a 12.5 to accommodate socks and enough toe room. Hiking/climbing is a much different feel than just walking and trying them on.


A Cadillac Escalade Ride and Fit

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

Wow, right out of the box and onto the PNW glaciers these boots never have gave me a problem. No break in needed just an awesome comfortable ride that kept my feet warm during many summit attempts throughout the PNW, even during a cold hunker on the side of Rainier in sub zero windchill.

The lacing system allows for great adjustment and locking at mid ankle and the feather-lite weight helps to keep your legs fresh for those long days.

They tend to run a bit small, so go up at least a half size to allow a great fit.

Totally agree! I normally get crazy cold feet but in these boots I haven't had any problems yet. Perhaps the Bentley of mountaineering boots?

Would these be good down to 20 degrees? if not what boots would you recommend?

As with most specific questions about gear: it depends. Namely, it depends on what activity level you'll be using them for. If you're moving quickly and don't size them too small (so you can layer a warm pair of wool socks underneath) these are a great technical ice and mixed climbing boot. The boot is also lightweight and sensitive, making it a great tool for all but the coldest, lower altitude, 4 season climbs. If you'll be pulling long belay duties in these temps, you may find yourself doing some calisthenic leg-swings to keep your toes warm.

Thanks for the reply Micah! You answer everything i needed to know , thank you.


I've used this same boots several times on Mt. Rainier (once in subzero temps due to storm), Mt Baker, Mt. Hood and other PNW peaks and they'll definitely keep your feet warm at 20 degrees. Just as Micah stated, don't get them too small. I in fact went up a size to allow for a thin pair of liner socks and a thick pair of SmartWool heavy trekking socks.

Thanks Scott! I think I'm going to go with these. I wear a size 9.5 in men's shoes. Size 10 for my hiking boots. I wear a liner and thick wool socks, should I get a 43 or go with a 43.5? How true to size do these boots usually run? Thanks for the responses!

Ron? not sure if you already bought these or not? If not, I have the same size foot as you, 9.5, and was worried about the size too. I actually ordered a 43.5 in this boot and a 43 in a mammut mamook. To me, they felt the same in terms of size. I kept the 43.5 Extreme? going out this weekend with them. Hope you have the same luck, will let you know how they

Thanks wayp417858! No, I haven't ordered them yet but was going to put an order in on Wednesday for the 43.5 a take a shot in the dark to see if they would fit. Now i fell better, hopefully they will fit good. Thank you and good luck on your trip!

Any chance you'll start carrying these in smaller sizes for women to buy? None of the light-weight boots for females take toe-bevel climbing crampons.

What size do you recommend for me. My feet size is 9 inches. I usually wear 10 inches hiking shoes. I'll be using this shoes in Alpine mountaineering.

Hey Bry,

Lets get your feet sized. You can print out the chart below to get your foot length converted to your shoe size. That way we are not putting you in the wrong boot.

Hi Wayne,

Thanks for the link you provided. I got my foot length - 9.5. Should i get the exact figure if I will buy the shoes or an inch larger to make room?

Hey Bry,

With these Trangos I would probably suggest you get the size 43 to be safe, and to make room for foot swell and thicker socks.

is this insulated?

is this insulated?

Hello Bry, thanks for the question.

Yes, these are insulated boots, here's the info from La Sportiva's website.

LINING: Gore-Tex Insulated Comfort Footwear

INSOLE: 9mm insulating Ibi-Thermo


Great Boot

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

I love these boots! Solid enough for crampons yet supple enough to handle some technical rock climbing, they are a great compromise for mixed alpine ascents. They generally stayed very dry. However, when I had to climb through spring runoff, they kept my feet dry for quite a while. When finally inundated by runoff, they still kept my feet warm despite being wet. The sizing is great as I have found La Sportiva fits me well and find what fits in one model runs true to size in another; these boots are no exception.


La Sportiva/ Trango Extreme Evo light GT

  • Gender:Male
  • Familiarity:I've put it through the wringer

I wore my new Trango Extreme EVO light GT's two days working around my property and was worried they were not broke in enough for my next big trip. I was wrong. I climbed Mt Whitney, Mt Shasta, Mt Hood, and Mt Rainer in a 2 week period and they have worked great. I encountered extreme heat on Whitney (88 degrees) and had no problems. Then on Mt Shasta we had 70 to 80 mph winds and a chill factor down to 0 degrees and my feet never got cold. They work great in the snow, with crampons, on snowshoes, in loose rock and just about everything a person could throw at them. Great boot.


as good as they get

  • Gender:Male
  • Familiarity:I've used it several times

i've used these for the past year, spring in the sierra nevada, early winter in mexico on a pair of volcanoes. they're are probably more durable boots out there but the warmth to weight ratio of these is unparalleled. cold feet have never been an issue. designed for technical jaunts at which they excel, but have also survived the miles of hiking i've put on them as well.

How do this Trango Extreme Evo compare...

How do this Trango Extreme Evo compare with the Nepal Evo GTX?

They are quite different boots. The Nepal is an incredibly warm comfortable boot for general winter mountaineering that in my opinion (and use) excel at long high altitude climbs. Super rigid but just enough flex in the ankle. The Trango Evo Extremes are much like the other models. Light weight mix climbing boots capable of tackling almost any terrain in early winters and late springs. For longer colder climbs Id pick the Nepal over these but on shorter technical routes these rule! Size up a half size as the heels fit real snug. cheers.


If you wanna look cool, buy these boots!

    Bought these last winter to use for some casual ice climbing and mountaineering. They've been good to me so far. Didn't feel like it took a particularly long time to break them in. Surprisingly cozy, in my opinion, for a mountaineering boot. My feet sweat a lot but haven't had too much trouble with these so far.

    I'm usually a size 10.5, depending on the shoe. My left foot is about 1/2 a size longer than my right and I've found with La Sportiva's it's always good to size up a half to a full size. I went for a size 45 on these and they work like a glove.

    Also, if you're looking for style points, I've gotten lots of comments on these from my more seasoned ice climbing buddies.
