I ordered them and have to return for a half size smaller. Here's what should be useful for others: 1) The size 11.5 was almost a full inch longer in the sole than an 11.5 Asolo 520 boot and my other Asolo boots. I'm returning for an 11 and really hoping that it will fit (concerned with the width). 11.5 is my size in two other asolo boots I have which I've hiked extensively in and never had a blister. 2) The weight is phenomenal. One size11.5 boot on an accurate kitchen scale was 2 lbs and half ounce, which is reasonably less that the Asolo 520 which is a hiking boot only. I've weighed my size in the La Sportiva Cubes and the Eiger is 6 ounces less per boot. 3) The tread depth is about 1/2 of that of a La Sportiva Nepal Cube, which probably aligns with the design goal of an ultralight, warm, approach and climbing boot that will more than likely have crampons on it if traction becomes an issue. I'm scrutinizing boots for a winter ascent of Shasta, likely the Casaval Ridge which is why I'm sweating the ounces and hoping these will be warm enough. I'll update this review if the trip happens. I had to choose a rating (stars) but obviously my rating is somewhat nugatory given I have not hiked in them yet, however I hope this info helps fellow online boot shoppers.

I would say that these run .5 size big, which is generally ok for hiking boots. The half gaiter keeps the boot warm and dry. I just hiked over 20 miles in 2 days in the Whites in NH in December, with several stream crossings, mixed slush, wet leaves, snow and ice and these boots did not disappoint. The soles have no flex, so the grip comes from Microspikes or Crampons, therefore, in the lower elevations in the mud and rocks watch your step before you "spike up" these boots. It's a great 2/3 step to a full mountaineering boot, at 1/3 the price with this SALE at $299.00!

As many already know, mountaineering boots vary significantly in fit. I ordered these in Size US 12 / 46.33 and they fit perfectly. I have Lowa Civetta Extremes in Size 45, and La Sportiva Nepal Cubes in Size 46.5. Scarpas are usually far too roomy for my foot, so I don't own any. These are very light which I want for longer approaches, and mixed alpine and snow climbs. They accept automatic crampons too. 😊

I've used this boot extensively on ice, mixed, and alpine climbs around the 48 states, Alps, Canadian Rockies. It is light and simply climbs amazingly well. The gaiter keeps snow out very well, similarly to the Scarpa Phantom Guide or a LaSportiva Batura. For sizing comparison, I use a 9 in the Eiger vs a 43 in the Nepal Evo. The materials used allow the boot to have a nice, small profile, but still provide a decent volume. I have relatively low-volume feet, and adding some Superfeet was crucial to getting my fit perfect and preventing heel lift.

I wore them for a 14er up Mt. Langley and they did great on dirt up the approach and awesome in the snow. No break was needed and didn't get any blisters going back down 8000' on rock and dirt with them. The sizing is right on to regular shoes

Well that is how these boot are made. I cant believe how tuff the boots are! Most recently I climbed little Costilla New Mexico. I had no problems. It was very cold and windy with deep snow! I never had a problem with wet feet. The foot never moved any time in need to stand up on the toe or kick in the snow. It felt like part of my body!

I write a lot of pretty good reviews - I might have to downgrade the others to make sure this one really shines! I have no idea how it works, but these boots are incredibly comfortable, even on huge approaches. That doesn't even start with how awesome they are for actual climbing - the flexibility of the top mixed with the sole stiffness make these feel like magic on rock, ice, or anything else you can throw at it. Considering how light these boots are, they are surprisingly warm, and it's hard to think of any other boot the same way again.

I spent some time hiking in the rain, glacier trekking, and ice climbing in these in AK this fall. There were great. Lightweight and kept my feet dry. The built in gaiter means you don't need a regular gaiter... one less thing to keep you from getting to the ice quicker! A nice upgrade to the Cholatse, which was also an awesome boot.

Do these boots have any insulation? Can...

Do these boots have any insulation? Can they be used for 2 day climb on 6k peak?
