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.

Feedback on Sizing, Performance TBD (s.b solid!)
Finding the right sizing on these was a bit tricky but REI made it easy! I wear a 9.5 US for street shoes, a 43.0 in a Bushido trail runner, a 42.0 in a Solution / Nago for rock climbing (nice and snug!), and oddly 42.0 wide in a Nucleo High II GTX. For the Nepal Cube, A 42.5 on this boot was perfect fit with a midweight sock but failed the triple kick test and was narrow at the forefoot; unbearably painful after two hours wearing. The 43.5 had enough room at the toe to pass the triple kick test, but had too much heel lift and was surprisingly tight at the forefoot. The 43.0 was snug with a heavyweight sock and the variable fit tongue, but roomier with a midweight sock. It passes the triple kick test, tight but comfortable at the foreheel, and there is a little heel lift that I should be able to lock in with an insert and lacing adjustments if they don't settle after breaking in. I could review the performance after I get them out on vertical ice, but I have a feeling nothing I say will bolster their already global five star reputation. I do prefer to climb as light as possible with a "simplify and add lightness" approach, and these are a bit heavier than I'd prefer. TL:DR - Reference on sizing only - Don't be like me and have a silly weekend walking around the house in 6 fruit boots wondering which pair felt the best, heel dropping and heel raising on stairs, trouncing up and down stairs, lapping from room to room, and kicking into the carpet and cement :) - Going half a size (e.g. 42.5 to 43.0) over your street shoe is a good starter - REI was a great source on helping to get the size right
Fantastic boots!
My old ice/mountaineering boots are Koflach Arctis Expe's and while they served me well, I decided to get a new boot this winter. The first day I climbed in the Cubes I fell in love with them. The temp was in the mid twenties and breezy and my feet never got cold and they performed fantastic. The fit is so much more secure feeling. My son tried them and they worked great for him too so I bought a second pair for him as well.
If the boot fits, wear it!
I originally bought a pair from the REI resupply for ½ the cost of new. Tag said used twice. They were size 10 (eu43), which is my foot size. And I have a wide foot. A person in my climbing class said they had decent volume in the front foot, unlike many La Sportiva shoes. When I put them on I felt they fit great, maybe a little snug. I figured I'd be okay if I didn't use real thick socks. The third time I wore them I discovered I truly needed more length. I truly needed a larger size. I Ended up trying on a pair of EU 44s and have used them once on steep snow with crampons. They are great. I did get a little hot spot on the heel, unlike the size 43, but it didn't blister, and I believe a better lace lock job would cure that. The heel really isn't slipping. I think I'll be very satisfied. Going to sell the small pair. I really like the lace system.
Nice boot, but beware the sizing...
I bought these boots to both ice climb in the UP of Michigan, and climb the glacier covered summits to over 20,000ft in Ecuador. My normal shoe size is 10.5 US and as always with boots I got a half size larger 11. With these boots that equates to a 44.5 European size, per the REI sizing chart. When they arrived they were small and had to be shipped back immediately. I grabbed my Danner boots, and my Eddie Bauer boots, both 11 and looked at the tag. They said size 11 US/45 European. REI's chart said 44.5 was an 11US, 45 was an 11.5 US. I spoke with a customer service rep, who was extremely helpful, and very pleasant. Explained the issue and she immediately shipped out a new pair size 45, unknown to me it was a 2 day overnight shipment, very pleased. She didn't even charge me to ship the boots back. Great service REI! So bottom line...of course for starters, get a half size bigger to account for your wool socks, BUT, the REI sizing chart is apparently an additional half size smaller in error. So consider ordering a full size bigger. These boots now fit very well! Can't wait to get the crampons on them.
Good all-around boots
These boots aren’t perfect, but they’re pretty good. The older generation of these boots were the first that I purchased for mountain climbing, and they’re still usable today. Fit is the most important factor when buying boots - they need to lock your heel in place, prevent toe bang, and allow circulation to your toes. Nepal Cubes have a reasonably wide foot and a narrower heel, which fits my EE wide pizza shape foot well. These boots are very popular at Alaskan ice crags so presumably they fit most people well. Another plus for ice climbers is that this boot provides great support for front pointing, which (at least in my experience) limits calf fatigue. I’ve tried a huge array of boots - Phantom Techs, Mont Blancs (several generations) and G5s, among others - and found that the softer, low cut boots cause more calf burn, which is an unwelcome distraction on lead. The leather uppers are highly durable, and I like adjustable laces all the way to my toes. I’ve used these boots to -10 deg F with warm toes. I run warm, so that might not be true for everyone. For cons, these boots are slightly heavier than other options. The Vibram sole wore faster than my Charmoz on scree. As with any step-in crampon boot, you have to baby the toe welt if you want to keep using a wire bail. (Side note, Petzl Lynx work great in full auto mode). I destroyed my toe welts in one outing of kicking down steep scree and ice. While it’s still there, it doesn’t persuade me my crampons will stay on. (A friend had a similar experience - his crampon fell off mid-climb). Scarpa’s boots generally have a deeper, more durable toe welt if you’re hard on boots, and you can always switch a modular crampon like the Lynx to basket mode. Another consideration is that leather can shrink. I own two pairs of these boots now, both 42.5. The older boots, which have been through an apocalypse of soaking, drying and rock bashing, are significantly tighter than the new boots. My toes touch the end when I step in, whereas with the newer boots I can wear a thick sock and still have toe room. I’m not sure if this can be mitigated with shoe trees or careful, low temperature drying. I wear the Norrona Flora Flex1 pants with these boots, and the fit is tight enough around the ankle that gaiters are unnecessary. For sizing, I am a 26.5 mondo and EE width, and I found that the 42.5 fits well, maybe a little large out of the box. As mentioned, I wear a thick mountaineering sock, not for warmth but to cushion some weird bumps on my feet that are irritated by stiff boots. This isn’t really a great comparison, but I wear a 41.5 in the La Sportiva TX3s (tight fit) and 42.5 in Altras, Oboz and the Scarpa Charmoz. Go as tight as you can with a reasonable size thickness and no toe bang; try them on several times throughout the day. Tl;dr: Warm toes, steep ice, not $1000, durable enough if you’re careful of the toe welts, can shrink a bit, fairly true to size.
Cannot be re soled
Boots are ok but REI is deceptively stating that they can be re soled. This is not true. I've spoken to dozens of boot repair companies all listed on la sportivas website and they all say that la sportiva refuses to send them soles for these boots. Without the soles they cannot fix the boots. REI should update the website.
Best hiking/climbing boot Icould have imagined!
Purchased as a dry tooling/hiking boot in Tennessee I can not say how great these boots are made, fit and work. No wonder climbers wear them everywhere! I would say if you are purchasing for trail/incline/powerline work then up your normal street/boot shoe by half size snd you’ll be good. This boot is DECADES ahead of anything used in the 80’s-90’s and IS HIKEABLE! Best boot I’ve owned since Lowa Tibet high. Kudos to REI Brentwood TN!!!
The Standard
Love these boots for ice climbing. Top performer.
First Impressions
Have half a season in these and the impression so far is very positive. The boots are comfortable, no issues with breaking them in, no awkward spots or pressure anywhere. The lacing system let's you dial in fit. Having the little rings lock of the lower half of the boot is quite nice and as long as you double knot the upper section stay tight as well. At lower temps (lower teens) I started to feel a bit cold, especially when belaying, but this is manageable with a double sock or just something thicker. One area which I think could be improved is the amount of space on the crampon lip, it could be a bit deeper. In deeper powder this did not disappoint, absolutely no snow got inside. For sizing I went with a 44 (I'm typically a US 10 in street shoes), and that gave ample room for the foot to move when using crampons without feeling loose in the heel.
Good fit out of the box.
First boots I’ve had that the first day of climbing was comfortable.
