Sizing Notes
For boots: Add one half size to your street shoe size. You should be able to slip one finger behind your heel when you are standing up with the boot unlaced and your toes touching the front. If the boot is too short, your toes will get smashed walking downhill. Too long and your heel will slide up and down and give you blisters.

Solid boot
I went up a half size or so, and it fits well, especially with thicker socks. I've done a few couloirs with it and love the light weight, super rugged and deep lugs, and solid construction. Waterproof and warm enough for spring mountaineering. Worked well with my crampons.
Top backside of ankle started coming apart
I haven't had these for a month and the material on the back of the ankle is starting to come apart on both boots. Really disappointed as I use these boots on a daily basis. Since they are under warranty, returning for a new pair and hope the next pair doesn't have the same issue. Or other issues.
Perfect Summer Mountain Boot
I just received my pair Wednesday night and took them up Mount Adams. These are very comfortable and worked well with my Grivel G12 crampons. They are relatively warm, waterproof, and light. Definitely like mine more than the Trangos. I recommend getting a half size bigger. Then loosening the very bottom lace when you put them on at first. I have wide feet and they worked well. They fit as comfortably as the NEPAL EVOS, with that snug, performance feel. Sole felt more comfortable than the Trangos and the bottom of the boot performed just as well.
Lots of positives, but issues for my feet
Review after testing these on a steep (gains >3000 ft. just in the first 1.5 mi.) mountain hike with scree, dirt, gravel, smooth and rough rock in dry conditions. Background - I have over 40 years of backpacking, mountaineering, and technical rock and ice climbing experience, and have used boots from every major brand and most styles. My feet are boot-fitting nightmares. I do not make callous and sweat heavily, so very prone to blistering. Have bone spurs on heels, and curled toes, not quite 'hammer toes' yet, but prone to blistering on tops of 'toe knuckles' during descents if not a generous toe box. One foot is 1/2 size larger than the other. Impressions: Out of the box, with medium thickness Darn Tough hiking socks, these felt snug, but comfortable, a technical fit similar to my LS Nepal Cube boots. At first, I didn't think there was any lace lock below the ankle, but upon closer inspection, the lowest lace hook is narrower and acts as a lace lock. These are 'B2 rated' boots, so more flexible and less rigid than B3 boots for more technical climbing. They have a pronounced rocker in front, and the angled heel behind which is unique. The heel lugs are very big, and the heel is a bit flared, and therefore didn't fit my Charlet-Moser Black Ice crampons. The ankle is fairly low, and flexible, which can help with balance when landing on off-camber rocks, and traversing side-sloping rock, but combined with the sole flexibility, would likely weaken the performance for front-pointing and edging. While hiking these moved like a dream. The combination of the flex and rocker made each step smooth and propels you forward, without the momentum-killing 'ker-thunk' of stiff, flat, mountain boots. On descent, the angled heel also smooths the landing, and gives more surface area on initial contact which prevents skating on gravel or smooth rock. The grip on all (dry in my test) surfaces was superb, and I had no sliding on scree, gravel, or dirt as I do with most other shoes and boots on this route. This could suggest a softer rubber compound that could result in shorter sole life, but I don't know about that yet. They don't appear to be re-soleable. After about 90 min of climbing, I got hot spots which turned to blisters on my heels, but that's not uncommon for me. I hope to be able to manage that with Leukotape and Engopads on my next test. More bothersome though, was while descending steeply. They felt great at first, without any toe-bang or much forward sliding which curls my toes and causes the toe-top blisters in my other boots. I found as I went along this was because they are narrow just before the first metatarsal bone (the 'bunion area') on side of the big toe, and that is what stopped my feet from sliding forward while descending and saved my toe nails. Unfortunately, it caused blisters in that area on both feet, which I've never had with any boot before. It could be a deal-breaker for me, but will try Leuko-taping those area on my next test as well, and lacing the forefoot more loosely on descent to see if I can find the sweet spot that still will prevent forward foot slippage. I hope I can get them to work for me. They are fairly light weight, and will make a great boot for summer or lower elevation alpine ascents, range traverses, and off-trail scrambling.
Great boots!
These boots are amazing! Took them for a climb to Mt Ellinor in the Olympics WA and didn't get any blisters or cold feet! Pair them with G12 Grivel crampons and were perfect climbing on snow!
Favorite boots
I’m on my second pair of these. They’re a bit heavy and can weigh you down after 10+ miles and an overnight pack, but i love them. I am really rough on my boots and the fact they lasted me a year was a sign to buy the same ones again. I generally hike in the Sierras and its all granite/rock/loose terrain. They wore out for me after exactly 1 year / 1000+ miles. They soles split on both shoes. In short they give great ankle support, nothing will stab through them and they’re pretty great at keeping your feet dry! I’ll keep buying them as long as they make them in this color combo honestly bright green and bright orange are my favorite!
Light, hikes well, comfortable
Bought these recently as a 3-season boot for Colorado 14ers for when I need something a little more than trail runners. The sizing is a bit different than other Sportiva models. I have the Nepal cube in 41.5, and I found these to fit similarly in size 42. For another comparison, I also have the TX4 in 41 for a performance fit, so consider sizing up 0.5 - 1.0 euro sizes. Width is medium -- I have a medium-wide foot and have had surgery for turf toe, so I typically need a roomier toebox. I wouldn't call the toebox roomy, but it works for me so far by fitting my foot shape perfectly.
Great winter boot
Have had these for a month now and REALLY enjoy them. Unlike my old La Sportivas, these are more flexible, lighter weight and the sole grips like crazy in the snow. I've taken them for hikes in snow and ice, snowshoeing, snowmobiling and submerged them in water for about an hour while clearing a drain. No leaks. And plenty warm with the correct socks. I do get a slight pinch from the left boot where it rests on my tibia (shin) but with minor adjustments it isn't noticeable. I would recommend buying boots about a half size larger, don't cramp your feet inside these and you will most likely be more comfortable. And, like most of the Sportivas, they are a good-looking boot.
A versatile mountain boot
Fit perfectly just like my La Sportiva Nucleo’s in the same size (46). Surprisingly comfortable for hiking in and the heel design work nicely on the downhills. Only used for rocky wet hike and scramble on Mt Monadnock in NH so far, but was enough to find out that these fit well, are supportive, and reliably waterproof. Crampon compatibility and the design around the ankle should make for a good winter boot too.
Lawn Bowling Boots
After four days of use in the Canadian Rockies, the unusual heel lugs snapped off. What looked like a thick durable rubber sole was actually brittle foam overlaid by thin rubber. These boots are very fragile and unsuitable as mountain boots.
