Baruntse Mountaineering Boot

For the cold, foreboding peaks of the world’s great ranges, La Sportiva created the sturdy, durable Men’s Baruntse Mountaineering Boot. With a PU-coated, two-layer insulating outer boot and a removable, thermo-moldable EVA inner boot, the Baruntse holds in warmth and blocks out snow and weather on high-altitude summit ridges and icy headwalls. A thermo-reflective aluminum layer in the shell helps conserve heat, and abrasion-resistant Cordura reinforcements on both the shell and inner boot hold up to rocky approaches and jagged alpine terrain.

  • Double boot for mountaineering 6000-7000 meter peaks
  • Cordura upper with transparent, expanded insulation netting
  • Thermo-moldable inner boot insulated with EVA foam and aluminum
  • Vibram Montagna with toe and heel welts for step-in crampon compatibility

These are Tanks

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 42

I've climbed a number of 6000m peaks in South America in these boots, and they are going strong. They are built like a tank and could last a lifetime for the average recreational climber. I've also done technical ice climbing in these, including summiting Alpamayo using these boots: 5,947 m (19,511 ft).

When fitted properly (the heat molded liners are a big plus, you can get them fitted at your local ski shop) they are very comfortable. The main downside is they are very heavy boots. You can get lighter boots if you are willing to spend more, but they are probably also less durable.

What size do you normally wear? I am a 42 in regular sneakers, but not sure if to get 42.5 or 43 given the extra layering on my foot.

Widow Makers

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: 42.5

If you plan on being taken out of the summit game the minute you put your boots on, then these are for you. They'll give you a great excuse when you fail, no doubt!

Just returned from Mt. Rainier and never made it past Ingraham Flats thanks to these terrible boots. The trek up from Paradise began immediately with deep slushy snow and those conditions persisted all the way up the Muir Snowfield to Camp Muir. No more then 30 minutes in I had to pull over to apply duct tape to my heels. By the fourth leg up to Camp Muir, my heels were utterly destroyed. When I debooted at camp, I had matchbox car sized blisters on the inside and across the back of my heels. Not a great place to be when you have many more days in these boots ahead of you. Long story short, on Summit day I only made it a quarter of the way and had to turn back. Favoring such damaged feet will ruin your footwork. Grunting in pain will ruin your wind. Said another way, the Sportiva Baruntse will ruin your bid. And after than, you still need to descend and that will be a mini death march of its own. I may actually go to urgent care tomorrow because this burn is so deep and feeling infected!

Heed this warning because I bought these after reading all of the other reviews, none of which were negative. Odd, right? Quick observations:

- The boot is very warm and beefy, no doubt about that
- Auto crampons like the Serac Pro wont work. The toe is too tall.
- The inner liner lacing system just sucks.. It only closes the liner; the laces are in no position to actually lock down your heel.
- The toe box of the outer boot is quite narrow, and may doom you to choosing a larger than necessary size
- The instructions for liner heat molding must be a straight babel fish translation from Italian, because they are anything but clear.
- No shin bang or toe slams
- They're too heavy

Lastly, the guides I was with, knew few, if any fellow climbers who spoke highly of the Sportiva Baruntse and these dudes are legit. None of them were wearing these...

I'll be reaching out to my gearhead hoping Backcountry has a similar policy as REI with this sort of thing because a $625 dollar mistake just sucks.

It all starts with your feet people so do yourself a favor and click the back button and never return to the Baruntse option again!

I had to complete opposite experience with these boots. When I was on Rainier last year in the beginning of May, we wore snowshoes all the way and these boots had no problem, I did not experience any hotspots or blister and just wore a lightweight DarnTough sock. The instructions for to mold the liner was very hard to translate but a quick search I was able to find step step by step directions on how to do it properly. I am sorry you had such a bad experience with these. I really wanted to like the Scarpa's but everyone has complained about how badly the zipper is on the new models. What new boot are you looking at now?

Why would you wear these on Rainier? Were you also wearing a 8,000 Meter parka that you want to complain about?

Beefy and warm

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

The coldest temp I've seen with this is 0, but windy with -25F. windchill My feet were comfortable - cool not cold.
La Sportiva has given thought to lacing up both the inner and outer boots, so that's pretty easy even with light gloves on.
Others (3) I climbed with had Baruntses as well, at least one had his for a couple years; the boots were all in good shape (scratched up some) - no complaints from anyone.
I would give 5 stars if the boots were a little lighter.
Of course, Backcountry always gets 5 stars!

Warm Boots

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 9

Bought the boots last month and used them twice in northeast winter hiking (~20 miles) in total in white mountain areas. They kept my feet super warm comparing to my previous boots (Scarpa Mont Blanc, of course, mont blanc is a single leather boots). As a price, these boots are very heavy and bulky. My BD contact crampon 's strap is too short for the boots, stinger worked fine. It should be enough for most non-technical Andes peaks, even for Aconcagua. These boots are more like a pair of high altitudes trekking boots. I used them once in ice climbing. It was OK but not as comfy as Nepal evo.

As to the size, my street shoe size are between 8-8.5 and I ordered a size 9. Everything worked fine except toe box. I felt the boots are squishing my toes after hours of hiking (with sock liner and smartwool heavy weight socks). Fortunately the liners are modable which makes it better but I can still feel it (I also skip the first eyelets). If you have wide feet you should probably choose Millet.



After remolding the liner and using a thin superfeet insole, it gets much better! I went to mt Madison in white mountain area last weekend. The temp was 0 F and wind chill was -29 F above treeline. The boots kept my feet warm (I was only wearing a pair of smartwool mid-weight socks).

Warm Boots


  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

So I was on the fence when it came to mountaineering boots and finding the pair that fit my foot the best. I did research after research between these and Scarpa Phantoms. I went with these and couldn't be happier about my decision. I have been wearing them around the house and just returned from a five mile ruck in them to aid in breaking in. I expected blisters or rubbing at the very least while the boot was breaking in. These boots are beyond comfortable right out of the box. I had no issues and can't wait to put these boots through the ringer. I couldn't be more pleased with them. I highly recommend these boots to anyone who is looking at them. I went with a size 42 as my Asolo's are size 10 US and my combat boots are 8.5 US. The 42 fits perfectly and no rubbing in the toe box at all.


  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: 47.5

Fits my street 13 well, with a little play in the heel, but 47 is too tight. There are tiny differences between L and R, but they are handmade, so there's that.
Warm as heck, didn't heat mold, and have seemed to form to feet just fine after several uses. Might mold down the road.
G12 new-matic crampons fit well, but if rear adjuster is fully open, otherwise it bulges the rear welt, and am a little concerned it might be too much tension and wear out that attachment point.
Would probably replace in kind when the need comes up!

Women Mountaineers! Try this boot.

  • Fit: True to size
  • Size Bought: 40

My usual US size is Women's 8.5 and the Baruntse 40 fits really well, with plenty of toe room while maintaining a snug fit. I found the more traditional lacing system an absolute must as compared to the Spantiks and other high tech lacing systems due to having Women's natural low placed calf muscles on short legs. Women, this is a thing! Mountaineer boots are designed for Men's bodies. I literally couldn't lace up the spantiks as there wasn't enough chord/lace to fit around my calf. I am not a large woman. To find this boot, I ordered two pairs and Spantiks (40& 40.5) and two pairs pairs of Baruntse (40 & 40.5). The Spantiks fit a bit snug and were much harder to get into. The Baruntse fit true to size and I found much easier to get on and off and adjust to fit my leg. I haven't taken these out on the Mountain yet but plan for them to be my boot for Aconcagua in January.

Huge shout out to gearhead Travis Bivens helping me go through 3 returns until I found just the right boot. Thanks!

Hey Sasha! Thank you for the review and the shout out! Keep me posted on how the field tests go during your training!

Thanks for the female perspective! I appreciate it!

Toasty warm toes

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 39.5

These boots are warm and comfortable. I am a female and 5'2''. I found these boots sit lower on the leg/calf than the Spantik's and so I found the Baruntse's to be more comfortable. I was a bit nervous about heating and moulding the liners but it was the best thing to do. Instructions are on the Sportiva website.

Best boots I have ever owned

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 44

I absolutely LOVE these boots. As a ski coach whom works in some seriously cold climates and stands in snow on contest days for up to 14 consecutive hours, these boots have never let me down.

They are completely water-proof and the internal liner is great which makes them really easy to dry. I went to my local boot-fitter and he molded my internal liner so the fit is absolutely amazing. The internal liner also gives me options to adjust my fit depending on what kind (and how many) socks I am wearing.

I ordered the same size as my Nepal's and they fit perfectly. I wear a US 10.5 and ordered a 44 and they fit perfect. I use my Nepals when I am in warm weather and my Baruntse when it drops below 25 degrees F. My feet get cold easily and I can stand for an entire day and not get cold. I most recently used them in Northern Finland where it can be very cold and never once had to think about my feet. I have broken my feet a couple of times and have a bunion, so the fact they are very rigid on the sole and though the mid-foot make them perfect for me. They still have ample ankle flexion so there is nothing that I can't do in them. They are warm, light- weight, and agile... I would recommend this boot to anyone!

I have found my boot for life!

Great boot

  • Familiarity: I've put it through the wringer

Great boot. Used on several 5000 and 6000m peaks in Ecuador and Peru. Never once had a problem with cold feet, using only a single pair of medium-weight wool socks - and was practically the only person in the group not to have problems with the cold. No hotspots or blisters even on 16 or 18h summit days, and only minimal break in. The heat moulding of the liners was surprisingly simple and made a world of difference in terms of fit - I molded them with green superfeet insoles. Super flexible and comfortable, quite technical. I wear 39/40 in normal shoes and decided on the 41.5 la sportivas, finding the 42 to be a bit too big.

Great mountaineering boots

  • Familiarity: I've used it several times

I purchased the Baruntse's for an expedition to Mt. Rainier. I literally lived in these things for the better part of 6 days. They were a little too warm for a summer ascent of Rainier but I appreciated the extra warmth at camp after the sun went down as well as on our summit bid which took place through the night and into the morning hours. On the upper mountain these things were super bomber. I cut up the rubber around the toe a bit with my crampons but nothing a little patch kit can't fix for me. I purchased the boot a full size up and they were perfect, no toe smashing and absolutely ZERO shin bang. I'll be using these this winter for a winter attempt of the Presidential Traverse in NH and hopefully on Denali and some of the volcanoes in South America. I absolutely recommend these.

Fantastic Boots

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

I think these boots are pretty fantastic. I use them for winter mountaineering and ice climbing in the northeast (mostly in the White Mountains in New Hampshire). I have yet to have cold feet in them, and I've been out when the temperatures were well below 0 F. I really like the flexible ankle, which makes the boots quite walkable, and is also really nice for more technical ice pitches. The lacing system is old school, but works really well and allows you to dial in a perfect fit. These seem to work well with almost all step in crampons as well. I haven't had any issues with durability and expect them to last quite a while, though I do think they will be slightly less durable than Nepals or another full leather boot.

I wear a size 11.5 in street shoes and running shoes, and I found that a size 45 fits me best. I am not an easy fit for boots since I have a relatively wide fore-foot, but a narrow heel (I also have bone spurs on my heels). I get good heel hold from the boot though. I tried a 46 also, but this seemed too big and I got a bunch of heel lift when trying them out on the stairs of my apartment.

One comment I will make though is that since these boots are hand made (or seem to be) there can be quite a lot of variation between boots. When I got my first pair, I noticed that the rocker was quite different from one boot to the other, and that the height and stiffness of the ankle was also quite different between the left and right boots. Even the sizing of the boots seemed different between right and left (and my feet are the same size). This was actually very obvious when walking around my apartment, and the fact that my stride felt very different from right to left was pretty annoying. I worked with Backcountry to resolve this and they were fantastic about helping me, but I thought I would throw this out there as one issue I had with the boots.

Great Once Fit Well

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

Since it's what everyone wonders, I'll open by saying I wear a 45.5 Nepal, and a 45 Baruntse. Arguably should have a 45.5, but the 45 gives me less heal lift than the larger sizes did and a better technical fit.

These are fantastic winter or cold weather boots, especially for overnight use. I've been using them for New Hampshire trips in the White Mountains so far, and they are perfect. I start to get chilly feet standing around for below zero F temperatures. The only time I've been actually cold was waking up to a 0F morning, my toes were pretty painful but warmed up soon when I started moving. I have very cold feet, I'm in serious cold-toes pain standing around in Nepals even at 32F, so no doubt these boots are way warmer.

People say these fit like Nepals and are "the warmer Nepal", but I didn't find that true. They can be adjusted to be, though! The Nepal fits my foot better than any boot I've ever worn, and the Baruntse was initially too narrow for the entire length of the boot. I had to get the toe box punched out, and then I went through a few iterations of punching out the mid-foot width myself (easy to do with a hot air gun). I also had to push the shell up around my 5th metatarsal as it was pushing down quite extensively and caused lots of aching. After forming the liners and four adjustments on the shells, they're finally wide enough and fit great!

The down-side: These are really fragile boots. I'm a little concerned about how the shells will hold up in the long run. I've taken them out on I think 12 trips, and the shells are already taking a beating. Nothing serious, but I imagine the material (fake leather I guess? not sure what to call it) at the front of the boot will become quite shredded. I always wear gaiters even if I don't need them to protect at least half the boot.
