Nuptse Mountaineering Boot

If you're looking for a high quality double boot for ice climbing, expeditions, or extreme winter camping/hiking (i.e. -20F) but dislike the stiffness of plastic boots, then this is the perfect boot. This is La Sportiva's only double boot, however it uses coated condura material plus an internal aluminal coating rather than the plastic/ankle hinge found on most double boots. I found them to be very comfortable, very warm, and of the highest quality. I have read some reviews that classified these as good only for high altitude and ice climbing, however I feel they are flexible and comfortable enough for glacier travel and long approaches as well. The boots come in half sizes up to 13, and La Sportiva is very responsive with customer service (in case you order the wrong size). I would order these 1/2 size larger, as they run just a little small, and you can always add insoles if you're wearing thin socks. At $440 these boots are definitely a worthwhile investment.

I bought these boots for a trip to the Cordillera Blanca to avoid frozen toes. These boots have performed perfectly well for me. They are comfortable right out of the box, no blisters or similar problems. And of course, and most importantly, they kept my feet nicely warm throughout the entire trip. Although double boots, they are surprisingly flexible and sensitive (much more than my old Koflachs). Amazingly good to wear also on rock and scree, the rubber compound of the sole seemed to give better friction than my friend's Vibram sole. As already stated previously, they run a little small (I normally have size 43.5-44 but got the Nuptses in 44.5) Otherwise, I haven't discovered a weakness yet. Five stars

After using this boot this climbing season I have to give it a five star rating.I ordered 1 full size over my street shoe sizing and have plenty of toe room for liner socks and 1 pair of warmer socks.Boots are very warm and the ankle flex makes walking on lower angeled terrain a painless endevour.After a great trip up Denali this June using this first class foot wear I have found the best double boot on the market.

These boots rock. They hike well, climb well, and they are warm and comfortable. The inner boot is warm alone in camp. They are plenty waterproof and stiff soled to boot. The new version is a bit lighter I believe but the price has jumped about $100 to around $530. I have used them for a few months now and have absolutely NO complaints.

I've used these for splitboarding, resort boarding, ice climbing snow travel and unintentional hiking during a 2 and a half week vacation in the states. I was really happy with the overall comfort, and very surprised at their comfort when I had to hike 4-5 miles or so on a closed road from the snowline to my car. Hiking up whitney's mountaineers route to the snow was also very comfortable, despite the heat. For their intended purposes they also performed very well.

My only complaint is that one of the webbing lacing eyes came undone, but when I sent them for warranty repair it was explained that it was due to an incorrect stitching (so appearantly not a design flaw).

These have been nice warm boots for everything from ice climbing to long trips out into the cold, icy, backcountry. They climb well and broke in very easily and now do just fine for long approaches. The only thing that could be improved is their weight.

Great boots, very warm. I was the only one of my group who didn't have to take my boots off to prevent frostbite during summit day on Aconcagua (including our head guide who wore Scarpas). They hiked well- no blisters! No complaints. I have what most would consider to be "low volume" feet. I bought mine from Andrew above (awagher).
