The "one thing does it all" concept almost never works, especially with boots, but here's one of those rare exceptions. If you have some vertical terrain or ice work on your trip, the Nepal EVO's are certainly at home in the more technical world- but your feet won't suffer on the approach hike in. These boots are the bomb for moderately cold weather, ice, snow, or mixed mountaineering. I've use them to establish our lower camps on peaks like K2, Annapurna, Broad Peak, etc. Unless you are prone to cold feet, these boots would work well on Mera, Island, or Orizaba and the other SA volcanoes. For increased versatility, I combine them either a gaiter and/or supergaiter to extend their cold weather range. Although you'll likely never find a better performing boot in this category, as with all footwear, fit is key. I have a flatter, low volume foot with a narrow heel.

Its a good boot, but these suckers should be GOLD standard and they are simply NOT. The lace locks are poor quality plastic thus providing an inconsistent experience out of the box and only wear out more in time. Yeah, the idea is great but they should have been metal or something that does not have so much give in them.

The do perform however; my BD Sabertooths hold well and the boots themselves have mad opportunity to be adjusted for a just right fit. I use for vertical ice climbing and this has been the best boot I have used to date as long as I keep moving. I have cold feet and I need multiple PAIRS of good socks to keep my feet warm with these boots. Several friends who are guides use them and have commented that they do not stay waterproof for long - GORTEX? I don't know... If mine start to leak, maybe I will try the new Mammut line as they look promising.

Bottom line - There are other options out there that will do for less $$$ unless you want the specifics this boot has to offer and you plan to use them. Overall, very pricey but if your a gear head, ehhh...

I am extremely anal retentive! I had 1 pair and they were so comfortable that I am using them for all of my journeys from hiking/exploring to glacier travel, ice climbing etc. I ended up buying a 2nd pair for fear that I might be without them for a couple weeks or so if I have to send them to be resoled. Overly anal?.... Probably but they're really that nice! I plan on using these everywhere and am certain they'll live up to Sportiva's claims!

Awesome mountaineering boots. These are my first full-shank leather boots for waterfall ice. I've climbed for a long time with Scarpa Inverno's and I haven't noticed a difference in warmth between them and the Nepal Evo's. These boots were very easy to break in----they were pretty much ready to go out of the box which was quite surprising! On alpine and waterfall ice routes they have performed amazingly well---the ability to move my ankles through a range of motion is a huge advantage when compared to climbing in double mountaineering boots. The Nepal Evo's might also be a good choice for people with a narrow heel & ankle as the they are the first boots I've had where I don't need to do fancy lacing or add inserts to lock my heels down to prevent them from moving inside the boot. Also, having the tongue inserts that come with the boots is a creative way to tweak the fit of these boots. Overall, I'm really pleased with the Nepal Evo's

These are by far the best mountaineering boots I've owned! Great support everywhere, great traction performance is incredible. I'd recommend these to anyone!

Just come back from a trip involving ice climbing, climbing an icy 10,000ft peak, scrambling on loose chossy rock & hiking. These boots did great at all. A bit stiff & hot for the hiking though but very grippy on rock. I would advise a few easier days in them 1st out to break them in & upgrade the inner soles. Saw heaps of pro guides wearing these.

Pros: fit right out of the box (literally did not need to break them in), Soft leather is extremely comfortable, the extra inserts help with warmth and custom fit (and you can take them out at night and throw them in your bag to dry fast, hold my BD Cyborg crampons very well (approach hiking & technical ice climbing), stable footing with great tread when not using crampons, lacing all the way down to the toe is great for a custom fit that lasts all day, the lace locking mechanism is really nice when trying to lace up with cold hands. I put these boots on and immediately forget about my feet so I can focus on the summit. Super Warm, took them out for a presidential traverse in February 2008 in NH. Mt Washington never got above -30F and I was toasty warm the whole time. Can't wait to take them out to Vail Colorado with me for the ski season!

Cons: lace locking system took a bit of practice before it became second nature.

These are absolutely incredible boots. I've seen several pro guides wear these, and with good reason, they are comfortable yet probably as warm as a single boots can be. they are stiff, climb and grip well and for a stiff mountaineering boot, they walk really well too. All in all, I can't say enough good things about this boot. The fit seems to be a little wider in the toe box than most Sportivas but it seems like this boot in particular fits such a wide range of feet. Although Sportiva definitely has the reputation of being a little on the narrow side i'd say these boot are right in the middle with a pretty narrow heel but I'm of fan of the fact that these boots fit like a glove!

These boots are great, they are extremely well built and the most comfortable boots ever. I mostly ice climb in these boots but also hike in them as well. One thing to be aware of is that when using crampons the heal bail can press into your heel if it is too tight. This isn't a huge problem is you are climbing but hiking in crampons like this can give you pretty bad blisters. Boots may be the most important piece of gear you can own so make sure you size them and fit your crampons properly.

Just used these for the first time this season. I climbed Mt. Antero (14269) in CO today, and they handled everything from kicksteps in hard ice, to loose scree and talus. Perfect boot for mixed winter climbing.

Finally got to take these boots up into the alpine. 10 miles round trip and only had a couple of presure points. These boots fit great right out of the box. They will take a bit more to get fully broken in, but I can't complain. Felt good hiking and were excellent on the steeper terain. Front pointing was a dream. I would recomend this boot to anyone looking for a high performance boot and one that will last.

I love these boots. Great fit, extremely comfortable, and warm enough for the winter ice climbing and mountaineering that I use these for. It is important to note that these are significantly warmer than the older version from several years ago, which did not have a Duratherm lining.

I bought these for Ranier and maybe Aconcogua. Haven't been to either yet but I have worn these on several winter 14ers in Colorado. Awsome boots. They fit a little narrow. I have medium width feet and these felt a bit snug at first. Now they feel great. Warm, waterproof and comfortable. They are stiff. They hold onto my BD sabertooth crampons like boot and crampon are one piece. I am a big fan of La Sportiva. These are the best for the money.

great boot great comfort warm and give great support .going to abc everest first thing i will pack.did killy in them good on trek in and brill on final night on the way to summit good all rounder.

I bought these boots a few days before a trip to Sequoia for a mountaineering skills seminar. They arrived the night before. I wore them around and they became easier to walk in as time went on. They are stiff, but not bad at all.

People were commenting on them as well as saying I was brave for wearing brand new boots for a 6 mile round trip. I wore some thin Smart Wool hiking socks, which were plenty warm. However, due to my skinny heal, the heel of the boot would travel up and down rubbing my heel, eventually a blister. I tried to tighten the laces, the lace locks are sweet, but without the tongue inserts, the bottoms of the lace eyelets pushed down into the top of my foot. I then took a break, put on heavy weight wool socks, tongue insert, and I was good to go, but the blisters still hurt. Once I got some mole skin and duct taped my heels, I was good to go for the rest of the trip. The bottoms of my feet were perfectly fine with no hot spots!

I only gave 4 stars since these haven't been put to any more torment. As far as warmth, as long as I was moving my feet were toasty, at night and sitting around, not so much, but I don't have good foot circulation. I don't give credit the boots credit for the blisters since I have a narrow heel.

Overall, awesome boot and awesome service from Backcountry.com!

I have had many different boots (Asolo, Scarpa, etc.) with good results but never could get the right fit (narrow heal, med-wide fore-foot, monkey toes). Went to The Fifth Season in Shasta City as they are some of the best fitters (I believe the owner fits) to see what they suggested for my desires (boot for mixed, steep ice, low 5th class rock) and they pulled out some beauts. By far the best was the EVO GTX in fit, weight, feel on the foot. The next day I ran up to and back from 12kft from Northgate on Shasta, first half on rock, second on snow with a new lighted step. Love the tongue insert and the neoprene like top. Later I had a 12 mile approach and wore these then mixed climbed. These are a dream I must say. I will not part with these boots! I've had them in every condition from -20F to 80F, scree, deep snow, ice, mixed, approach, etc. getting ready for the second resole. You will have to cut them off my feet when I am dead!

I'm giving five stars to these boots, even though I have yet to test them in the elements; however, I don't think I will have to retract any stars when I do. I have been wearing them in and about for the past weeks and they feel really good. I bought both sizes 45.5 and 46 because I found EU to US sizing was not consistent. I wear a 12 boot and found the 45.5 to be the fit. The leather is taught when you put them on, but it relaxes to your feet as you wear them. l learned from La Sportiva's website that you always should put your boots on standing up so your foot is extended; it works. These boots are warm, just enough roominess, great ankle support, very cool lace locking mechanism, and as my daughter stated, "They are Rasta colors, cool." My Black Diamond crampons fits perfectly. I can't wait to take these and snow climb the Crescent Moon Coulior on Round Top in the Sierras end of this month and the Mountaineer's Route of Whitney in early May. I will continue this review when these are put to the test. But if I can wear a Mountaineering boot comfortably in everyday life, I think it's a good indication these will do quite well in the mountains.
