A tough double-boot for the high-altitude realms of the world.

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.

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.

Awkward rocker

  • Fit: Runs large

I ordered a pair of these in 43 and 43.5. Both were too tight on my somewhat wide foot with high arches. I wear a 9.5 US normally. Mostly though, these boots are heavy and cumbersome. I felt disconnected from the ground and had a poor feel for where I was stepping. I also had trouble walking on flat ground, I think these would be very hard for the approach. I ended up ordering the spantiks and really like those. It is an extremely well constructed boot though and if the fit was better they may have been great, not for my foot though.

Posted on

I have a pair of the Baruntse that I climbed Aconcagua in last year.Loved them,no problems whatsoever.Several of the other climbers in my group had them and felt the same way.I am going back this January to climb the Polish Direct.I purchased a pair of the Scarpa Phantom 6000.They are about 10 ounces lighter than the Baruntse per boot.(I weighed them on my digital scale) I have a wide foot 4 E + and a high arch. I have found the phantoms to be a tad bit smaller (lower volume wise at the same length) consequently I usually wear a mid weight sock compared to a heavy weight with the Baruntse . My question is, will they keep my feet warm.I have done several winter ascents on 4000 meter peaks in deep snow on zero degree/windy days without any cold issues wearing the phantoms 6000. Considering the fairly significant weight difference I would prefer the lighter weight boot especially on summit day. Any thoughts on this ?

Responded on

Hey there--the Phantom 6000 is a great boot for Aconcagua and as such, is included in a number of major guiding company's recommended equipment lists. See here:

You'll definitely notice the 10oz gone off your feet--that's a huge difference right there. Assuming you're an efficient and skilled climber, the Phantom 6000's should be a perfect boot for you. Good luck on the Polish Direct!

Got two pairs to try, normally wear a size 12 hiking boots, have wide feet.
1. 45.5 outer with a 45.5/46.0 inner
2. 46.5 outer with a 46.5/47.0 inner.

-How much space should I have on the side of my feet at the widest part? It is not tight, but snug.

-How much toe space should I have?
If I kick a wall in the 45.5 outer, my toes will not hit the front, but my toes will notice where the front is. They will slide forward as I keep on kicking. I have about 1 finger width space in the front of the liner.
In the 46.5 I have about 2 fingers space in the front of the liner and will never even notice the front of the boot.

I do not want to get a boot that is too big.
Will heat moulding make more space in the toe area if I allow enough space with a toe cap?

I am wearing a thin liner and Heavy Smartwool socks.

Posted on

Going through the list of reviews I am coming to an understanding that to properly size my boot I must order up to three different pairs to see which one fits best (no suppliers near me). Well, I can't shell out that kind of money right now and I would like to get as close as possible on the size on the first try. Across the board I am a size 10.5; climbing shoes, sneakers, hiking boots. I have a pair of LS Xplorers that are size 44 and fit just fine. Not too big, not too small. Would a 44 be an appropriate place to start? Can anyone give me a comparison of their street shoe size to the Baruntse's?

Best Answer Responded on

If there aren't any suppliers near you, I would order the 44.5 (US 11). Try it with thick socks and potentially an insole. If it doesn't fit after a few trips around the house, then work with BC on a return. Hope this helps.

Responded on

Thanks Jeff. I'll see what BC can do for me.

Dear Bryan, i'm facing a similar conundrum. What size did you eventually end up getting?

I actually have yet to purchase a pair because I really need to try them on. In a couple of weeks I will be in CO and will try on a pair.

planning on climbing mt bona(16,421ft)in alaska soon, and planned on wearing these boots. the company i would be going with suggested i have an overboot and im not a fan of overboots. so the question is should i just go with and 8000 meter boot like the olympus mons or should i just go with a different company and just wear the baruntse's?

Best Answer Responded on

You've gotta assume they know what they're doing, so if they recommend an overboot, and you hate them, use a warmer boot like the Olympus Mons or Phantom 8000. Did they suggest, or demand that you wear overboots? You could just not wear them and tell the company you'll deal with it. I'd go with the warmer boots and protect your feet.

Posted on

I need to replace a pair of plastic double boots (an older model Asolo AFS 8000) with something new. I use my mountaineering boots for climbing on vertical ice and for multi-day, backcountry winter treks in the New England mountains rather than high altitude mountaineering. Rainier is most likely the tallest glaciated peak I'll climb in the next five years. I just want to buy one boot to cover all my needs. Can the Baruntse fit the bill, or will I later be finding myself pining for the Nepal EVO GTX? (I can't afford to buy both, of course). Thanks all!

Best Answer Responded on

Mike, I think these boots would fit your needs. I would rather hike in the Nepals but these boots are warmer.

If you know what size you wear you can usually find these for about half the price on which sells excess and returned stock for Backcountry. But, they do not accept returns if they are the wrong size.

Posted on

i found the instructions for heat molding these confusing. not sure what toe cap hight is, or what a foot bed is (that aka a insole?) if anyone as clearer instructions id be in your debt, thx.

Best Answer Responded on

The foot bed is the insole. I have no idea what those crazy Italians mean by "top-cap." The procedure is pretty standard for molding liners:

You'll want to use a convection oven to make sure the liners heat evenly. Preheat to 250º. Place the liners in the oven - I've heard on a foil-lined cookie sheet, but I've used the bare rack without issue - for 10-15 minutes. You want them to look puffed up like a marshmallow.

While they're heating, prep your feet. I like to use the same socks I'll be using in the boots later to get the right fit. Put a neoprene toe cap on under the sock. If you don't have toe caps, you can make them out of whatever you have around the house. The point is to spread your toes a little bit to give them room once the boot cools. I've used cotton balls and packaging tape.

Also, grab a 2x4 out of the garage and put it on the floor.

When the liners are heated up, pull them out, toss your footbeds in there and put them on your feet, cranking the inner laces. Then shove your liner-clad feet into the boots, being careful to keep them straight and not snag them on anything. Lace them like you normally wear them, kick your heels to get them set into the boots, and stand with the toes of the boots on the 2x4 for about 10 minutes. At the end of the 10 minutes, pull your feet out, tie the boots back up, and let them sit until they cool entirely.

Also, never listen to Italians. They'll try to steal your women.

Is this too much boot for ice/winter/spring mountaineering in the cascades, and summer trips on rainier/baker? i'm prone to cold feet.

Responded on

Nick, these are a decent all-around boot and should work for your intended adventures. If you are prone to cold feet these should fix that.

Responded on

Similar/follow up question: haven't received mine yet (I'm a very large size and haven't been able to try them on), but I'm curious if they'll be possibly ok for the trip up to Muir or should I still plan on carrying them up while I hike in something else. Typically I have to hike a very heavy backpacking boot anyhow due to trashed ankles. Thanks!

Posted on

So I've tried on a few pairs of these and the fit is great except for under the arch of my foot. I've got moderately high arches and when feeling in the boot shell I can feel a rather pronounced dip right after the arch. I know this part won't change any, but will custom molding the liner or adding superfeet insoles help, along with breaking it in?

Maybe I'm just not a good fit for La Sportiva. Any feedback is appreciated.

Best Answer Responded on

I have low arches and I have similar issues with finding a good fit. Proper fitted insoles will help, but then the question is, will the boot then be too tight? I've found I either have to size up or find a wide width to make up fot it.
Before comitting, try them on with insoles you know will work for you, along with your regular liner/sock combination. The last thing you need is to cut off circulation in a cold enviornment.

Responded on

Thanks for reply. I'm getting some superfeet insoles tomorrow and will see how they work with those. I think I'll stick to a half size bigger (as I ordered two and will send one back), since the boots have a nice way to tighten the upper ankle without tightening the toe box too much.

I haven't personally used them, but my local club rents them out for ice climbing and they seem to do really well. They have all the features you'd want in a ice climbing boot. My Scarpa Mont Blanc are similar and work great.

These Bad Boys are Awesome!

OK. Doing some background research I decided to try two sizes and then return the one I least like. I often wear size US 11 (men's) in street shoes. That depends. Some times I have to go larger. I have a pair of Asolo Fugitive backpacking boots that are size 11.5 I believe. They're fine but sometimes I wonder if I should have size 12. I mention all of this just so that you have more information on your possible sizing. Anyway, I decided to try the Baruntse in sizes 45.5 and 46. It turns out I prefer the 46, even though that just seems like it'd be way too super huge. I was tempted to go with the 45.5 (temptation probably stemming from my experience downsizing snowboard boots so that they fit better on the board). The 46 simply felt like there'd be fewer issues involving possible blisters, etc. I've taken them on a couple outings already and they stick well (after tightening the top laces a lot) and I have no blisters. 46 was definitely the way to go for me.

As far as the shoe itself goes, it's great! I'm very happy with it so far. It feels good and secure. I imagine it'd keep water out better than the Scarpa Inverno because there are no possible entry points for melted water. The liner's a little funky. Something on the liner agitates the top of my foot after a long day. It might be the tie-in point. I'm going to investigate it further and possibly modify it.
