This boot is the best light weight climbing boot around, unbelievable summer alpine boot. Comfy, light and versatile. Definitely lacks in the ice climbing department, due to the 3/4 shank, but they will get you through an ice pitch if you need them too.

These boots are light and relatively warm. They run a little narrow for my medium-wide foot. I take care of that by bringing them to my local cobbler who throws them in the stretcher overnight and then I am good to go! They are so light that they wear faster than heavier boots. If you want a super durable boot then get something else. But if you want "the" boot for climbing peaks in Patagonia or many other places, you can't do better then this boot.

About 3/4 of my SAR team colleagues have these. They are light, comfortable hikers, yet have the support for moderate crampon work and high angled environs. The seem to excel on moderate rock and scrambling, making them an great boot for the mountain rescue application. The Trango S are not insulated, so extended periods in snow my result in cold feet. These boots are made with cutting edge design and materials for unparalleled weight and performance, making them a little vulnerable to wear and tear. If you are looking for more durability, I suggest the Glacier or Glacier Evo, but if you are looking for performance, look no further.

These boots are amazing. Great spring or summer mountaineering boot. Light enough and flexible enough that a long approach to the snow isn't an issue and still still enough that it takes a crampon great and provides ample support in the snow.

Used this boot to climb mount Rainier in July. Was a little chilly standing on snow in camp, but i just stood on a pad if i wasn't moving around. Used this in the wind river range. Back packed over 50 miles on that trip including Ganet peak. Plenty warm.

Love these books. Worth the money. They are really low-weight. I don't have to make the trade off between weight and ankle support. (I would have twisted my ankle twice yesterday if I didn't have the hightops.) Will be using these on my Mt. Whitney Mountaineering route trek in two weeks. Double socks recommended in order to reduce friction.

Any mountain boot is a balance between weight, comfort and utility. Over optimizing on one compromises the others. In my opinion, these boots have hit the sweet spot.

They are very low weight, which makes them easy to wear, and flexible. I have used them on a 6000m peak in the Andes, plus a couple of semi-techincal 5000m peaks, and they were not too cold (I used toe warmers), plus they allow enough ankle articulation to prevent your knees from getting hammered when hitting long days in crampons. A HUGE improvement over my plastics.

These boots are incredible - I used them with my Grivel 12 pt automatics, and they performed flawlessly. I can strongly recommend them for just about any alpine conditions I can think of outside of super cold regions like Alaska. The best purchase I have made for awhile and well worth the money.

On the negative side, they don't provide the ankle support / toe pointing ability of full plastics. I have used them for some ice climbing, but they are more tiring to use, and are probably not the right tool for the job.

PS: Did I mention how incredibly comfortable they are?

My motives weren't quite so grand as the other reviewers, I just wanted a boot I could use for everything, and these are just the trick. Had always used 3 season boots before but had aspirations for all year round and further afield through europe etc. I can safely say I have thrown everything at these boots without failure. Mid summer mountain walks where its been hot where my feet have been slightly damp through sweat, mid British winter with wind, much rain and snow with dry feet slightly damp through sweat again, no change, I've scrambled, this is where these boots really come into their own. Solid assured yet light and comfortable. Pity they have a disco theme colour scheme. Only fault I can find. If they made an all black boot I'd buy them for work (military). Expensive but worth every penny.

I have a difficult to fit foot. Narrow with a narrow heel. I often have trouble finding boots that fit. The Trango S EVO GTX fits great. I can snug them down and they hold my foot comfortably. They are great to hike in, with enough rocker to make up for the stiffness of the sole. I have never had a problem kicking steps, the boot is solid and my foot is held solidly so I don't have any toe bang, with my foot sliding to the front. A great boot for scrambling adventures where snow and rock are mixed.

I agree with most of what others have said. Short version, great boot, minimal break in required, comfy, runs on the narrow side, stiff, great traction on rocks, replace the insole with at least a normal trail running shoe type insole.

I put about 5 miles on these with a pack before taking them out on their first trip. I tend to be more prone to blisters and didn't get any on an 18 mile trek with 20lb pack.

As far as I know I have normal width feet and I do notice that it's a bit on the narrow side as some have mentioned. Not narrow enough to cause me any issues.

The insole that they come with I'd suggest throwing out though don't replace it with green feet or similar bulky insert. All it needs is a normal insole as is found in like a trail running shoe. I took the insoles from my la sportiva trail shoes and put them in they work perfect, w/o all the bulk that the other type of insole would add. I don't see how anyone could even have the boot still fit if they added one of those soles, but I guess they have.

Anyway if they'd just put a regular insole into these with a bit of padding vs the paper thin no shock one that's in them it'd be fine. I did an 18 mile hike with about a 20lb pack on my first major trek, and my knees were very sensitive and beat up feeling the next day. After adding the trail running shoe insoles it was fine for the same length trip afterwards.

Boots have been waterproof for me so far but I've done nothing more than gentle stream crossings.

They've been plenty warm for me so far down to 40 degrees with expedition super wool type socks, they are a little bit on the hot side for warmer weather due to the snug fit and waterproofing I assume.

It's very easy to really snug this down around your ankle if you like to they have great support.

I"m using them for normal hiking boots because I'm usually climbing up some peak as the goal, and was rather shocked at how quickly they're wearing so far, but that is the price for such light boots I guess.

I've used them fine with stubai ultralight universal crampons they worked great.

My foot is size 10 I've never worn anything but a 10 or equivalent in euro the 43.5s fit me great. I suggest you checout the chart on la sportivas site for fitting.

I really like these boots. I am generally pretty tough on my gear and these boots can really stand up to whatever you hand them. Great for slightly technical summit attempts where some good edging will be involved. Take crampons very well because of the shank. Did great on mixed rock ascents, as well as a long couloir with crampons. My only complaint which is more of operator error than manufacturer fault is that they are not very well insulated. If you are expecting cold weather make sure you wear heavy socks. These boots are great for Spring, Summer, and Fall asecnts. For winter however I might recommend something heavier.

i wear an 11 in nike and montrail, and a 44.5 in this boot with room for thin wicking liners under midweight wool hiking socks from wigwam -my foot measures a D width.great fit, easy to adjust lower boot fit from ankle fit via lace locks -nice feature.i climbed for about 8 hours in these in crampons in snow and ice -pretty warm with only minimal numbness in the toes during the dawn hours on the frozen ice.i had little time to break these in (just a 3 mile loop up and stair climbing), but they felt so good, i was OK wearing them for a multi day trip without worry. they break in like a sneaker -fast and easy.I wore the OEM feetbed, but will switch to my normal superfeet greens for better stability and fit.This boot is a perfect balance between a mid-weight hiker and a mountaineering boot with plenty of stiffness for crampons (i used BD contact straps).I found the sole of the shoe extremely grippy on wet and dry rock, and even on ice w/o crampons they seemed to grip pretty well. overall, i'm very satisfied with this boot, and would recommend for cooler weather/heavier packs and of course summer mountaineering. for reference, my first trip in these was with a 32lb pack over 18 miles and 6000 feet of elevation gain trail/rock/scree/snow/ice. The boot showed no sign of wear on the upper, rand, and soles were even pretty much new looking. i probably wouldn't wear this boot unless i need crampons or expect extreme wetness, so i expect them to last a very long time even with their softer sole. for lighter packs and all-dry climbing, i'd wear a lighter boot or shoe, although given the support and funtionality, these boots are extremely light! cheers.

yeah,they are light, they look good, are supportive, etc - too bad they just don't fit a normal foot, nor do they last long enough to get them broken in.

These boots are too narrow - my cobbler claims there's no way to stretch them due ot the protective rubber. My feet are actually narrow and the length of the boot is perfect, but after 15 miles of hiking I have numb toes for half the night following the hike. Worse: the shoe soles come apart after less than 200 miles, so that now I am stuck with boots that have to be replaced. The local shoe repair guy claims unless he has the special glue the factory uses, he cannot fix the part where the red foam is separating from the yellow layer on the left heel. Then I post here to get an answer regarding that alleged lifetime warranty (go to La Sportiva and there they only know of a one year warranty), but my post gets flagged as misplaced. Well, the boot is less than a year old, but nobody here at this site bothers to answer my question about the warranty claim process - La Sportiva wants you to go through the vendor. Bottom line - a shoe that expensive should not come apart from light use (no climbing, just walking on a marked trail), and if it does somebody should honor the alleged warranty that is being advertised right here on this page right below the weight.

Back to reliable Lowa of Koflach for me - at least they know how to glue their stuff together.

Comfortable right out of the box. They say its a 3-season boot but I've been using them this winter and my toes stay pretty toasty down to about 10 degrees.

I love this boot! They give great ankle support (I have been able to backpacked with a sprained ankle thats to these). They have great traction when going up rocks! Well worth the money. I did put in a insole but they are super comfortable.

I miss the old green leather Trangos of the past. I had to finally give mine up when they failed at the soles somewhere in Nepal, but it took ten years of hard use to accomplish this. I replaced them with the new red Trango S EVO GTX (what the hell is with that name - have the guys in Italy completely lost their minds? Should they come up out of the boot cobbler's dungeon and get some fresh air?) and, I have to say, that I love them! They are super light (a future drawback that I will have to pay for I'm sure), have good support, and just fit like a glove. I am, and always will be, a Sportiva man. Whatever last they build shoes on seems to be the perfect fit for my hideously deformed foot and toes. But I know two other people that have them, taken them to the Alps and Tetons, and are also in love with them. I once wore them on a late fall climb up the Kautz headwall on Rainier, and other than cursing the lack of rigid crampons, they performed well - even with the foot of snow, the roaring wind, the whiteout, the descent into the abyss, becoming lost on the Nisqually Glacier, and the cold and rain - they did well. I can, however, see wear in them that is quite accelerated when compared to a full leather boot. I would guess that with heavy use these will see half the years of my old green Trangos, but they are so light.

Long backcountry trip in the ADKs, temps in the teens, neg temps at night, thrashing backcountry snowshoeing, kicking alpine steps, mixed ice and rock, white-out conditions, wet bag - toes? Warm and toasty. By far the lightest boots I have owned. Paired with smartwools, go all day. Laces froze up, but other than that, light ,sticky, fast boots. When Sportiva discontinues, let me know -- I will buy all of their stock. And backcountry.com? Awesome service. Ordered two pairs to get fit, free shipping return. Will be return customer. Oh, and took these boots into the backcountry without any break-in. Not a blister or hotspot. Most impressed.

Wore them in the rain above 10,000 feet for four days. Hardly took them off. Feet stayed warm and dry. Fit great right out of the box.

Remained waterproof through snow, water and all the other crap the Pacific Northwest throws at us. Lightweight also. I have narrow feet and like a snug fit. These fit the bill well.

I have owned it for one season and have worn it to the top of Jefferson, Hood, Rainier, Baker, Shuksan, Eldorado, little T and some other local peaks. They won't weigh your feet down. If you want something warmer, however, e.g. Mt Rainier in the winter/spring, I'd recommend La Sportiva Glacier.

My only complaints is these boots don't stand much abuse. Mine have already shown signs of wear and tear after one season. I had to glue the rands on both boots. I have been wearing them pretty much every weekend since spring though.

Overall great boot. Comfortable hiker under heavy loads. I wear them at work everyday and find the comfortable enough for all day wear. Have not done any extensive climbing in the yet, so I can't speak for them there. Stayed dry during some spring backpacking in snow and stream crossings. Awesome product.

I've owned them for 2+ years now. It's a good day boot for me, but not an overnighter.

My feet get cold in these and they don't dry out well in a tent on a glacier. There are no removable boot liners to put in your sleeping bag. I hate putting wet (sweat/condensation) boots on the next day.

They don't replace plastics (for me). Even at double the weight I still pick the plastics everytime for glacier climbing on the PNW.

My heels get hot spots when cramponing all day. With the plastics on I have no problems.

I wore them in Colorado this summer on 14er's. They performed well, but a hiking boot at half the cost would have also.

You might love em. I don't hate em. But wouldn't get another pair.

Hope that helps.

I, too, was torn between these and the Makalus. I actually got both, but have worn these on 6 fourteeners so far. They did chew the tops of my outer toes a bit, but I taped them and so no problem. On a 3rd class ridge, they were superb. Edging is phenomenal and they aided my accent in a huge way. They're also waterproof, and don't rub my feet in any meaningful way. They tend to wear quickly, but they perform so well I won't have a problem buying another pair. And now I have the Makalus: these Trangos are so much lighter! For scrambling/mountaineering, get these.
Cheers.

Done a couple of local day hikes to help break them in. Feel great, no hot spots, and except for the razzing I get for the fancy color scheme I think these boots will be perfect. I have had them in the snow for some snow and ice rescue training. I also built an igloo wearing these boots. All of this for a total of approx 10 hours and my feet never got wet or cold (with just one pair of regular socks).

I bought my Trango S EVO GTX online with some reservations. New to mountaineering, I wanted something that will work right away. I was torn between getting the tried and true Makulu or these boots. In the end, the Trango performed beautifully on Mount Rainier and I can highly recommend them.

They felt comfortable right out of the box. I trained in them for a few weeks before heading up to Seattle for the Mount Rainier acid test. During the training runs, the boots went through rocks, sand, streams, hills, and grass. No leaks and no major issues. I did get a small blister coming down a 1,700ft hike with a 40lb pack.

Time came for the Rainier test. We took the Ingraham Direct route. On the first day from Paradise to Muir Flat, the weather was awful -- complete whiteout. No visibility, rain at the lower elevations, and snow on the Muir Snow Field. Had to kick steps into the snow with the front of the boots for 2 miles and 3,000 vertical feet. No problems! The boots felt light and easy to use.

The second day was the summit bid -- crampons, ice axe, and rope teams. Again, the boots performed well. I used Grivel Air Tech Light crampons with the anti-bott device. The crampons fit onto the boots easily and almost felt like they weren't there. (BTW, get the anti-bott! It's worth every penny.) We went through hard snow in the morning, and complete slush in the afternoon. Again the boots did very well. Front pointing in the crampons with these boots felt natural and easy.

Descending from the summit was an adventure. The hot sun melted a lot of the snow, so we were post-holing a lot. Especially on the Muir Snowfield. The slushy snow went up to our knees with every step. The boots felt great and secure. My feet were in complete comfort. No blisters either, after I put on merino wool socks with a pair of smooth liner socks.

When I finally took the boots off back at Paradise parking lot, I did notice that my socks were damp after 17 hours of straight hiking in these boots. However, I think some of it was sweat. Anyway, the boots felt dry the whole way and my feet were very comfortable. I can forgive the dampness after such a long grueling trek. I was very happy with the Trango S EVO GTX, and will heartily recommend them.

I used these in the Alps and most notably on the Matterhorn. This is a perfect boot for Matterhorn-style, mixed rock and snow climbing. They are very light and nimble on rock sections but stiff enough for crampons. I had one small blister the first time I wore them but no big deal (almost no break-in necessary.) I am fairly disappointed with the quality control however. I've seen a few pairs and on some the sole is cut flush with the boot (as it should be) and on others the sole sticks out a quarter inch around the boot. Also certain pieces of the upper were completely off center (for example, the tongue on my left boot is severely off to the side instead of being centered.) Fortunately none of this affected performance and overall I think it's a great boot.

Almost no break-in time for these incredibly light, comfortable hybrids. I put these to the test on Mount Elbrus two weeks ago. They got me to the 18,513 summit and turned out to be the perfect boot for the climb. I would be cautious about wearing them in temps much below 15-20F, and despite the Gore-Tex they weren't entirely waterproof. However, their light weight and comfort outweighed these negatives.

After reading all the reviews and the hype I was still somewhat skeptical. After 8 days in the bugaboos I'm a believer they are super light, comfy right out of the box, great on the trail, work stellar with my Grivel G12's, and work great climbing. 5.6 trad was no problem, jam well in the cracks and rubber is incredibly sticky. Would definitely recommend them. Only drawback would be the fire engine red.

Loved these boots. Only took a day hike and an overnight trip to break 'em in. My foot fits well in Merrell and North Face boots and my foot fit fine in these too.

I wasn't so lucky and I did have a break-in period, but on a recent 4-day trip, there was no discomfort and no blisters.

Super versatile on my recent trip as we crossed creeks and hiked through scree, scrambled over rocks and traversed ice and snow fields.

Being new to hiking and living in Utah, I wanted boots that would be light weight and perform right out of the box with little break in. Let me tell you what, I was not disappointed at all. From the first time that I put these boots on and went for a hike I have been telling people that they were well worth it.

Awesome boots. MY feet have never gotten cold or wet in these. They will go through the mud and water at lower elevations and perform well in tough snow pack up high. Look no further, this is a great all around boot.

Never thought in a million years I would get into technical ice climbing. Obviously these boots aren't made for that, but heck they have been doing a fine job. I bought these boots with the intentions of long approaches with glacier travel like gannet peak. Great for hiking, work very well with BD saber tooths. Any how, I went out first day ice climbing with a friend at a very popular area and got laughed at by just about everyone that I was wearing that combo. By the end of the day I was finishing up WI4+ on TR and the next time leading WI3. Boots and crampons worked well, I think their were a lot of very surprised people their that day, including myself.

These will wear out after 30 days in the mountains. Granted I'm using them in the Canadian Back Country, but I am surely disappointed. A good pair of full leather boots have lasted much longer in the same conditions. It's a shame, I wish, because the first day I had them was amazing. They're OK when light is right, but avoid scree slopes at all costs.

I just measured my foot. It's 27,5 cm long. What size is this? 9,5 US, 42,5 EU???? I really need to buy a pair of these, but I can't decide on the size.

The best fiting boot i have ever tried on. I might even use it in the sumer.

This boot like all La Sportivas are for narrow feet. These boots are for alpine/mountaineering junkies! snow shoeing, ice climbing, snowmobiling, and every other winter/fall/spring use period. Light boot. Durable boot. Best boot ever built!. Yes they cost 285 bucks. And you will be thanking yourself later! Let me make this clear if you don't get the point. Michael Jordan said, " Its the shoes!" Well if Michael Jordan wore these boots. He'd have 14 championship rings instead of only 6! These baby are like REDBULL. They give you wings!!
