Sizing notes

For rock climbing shoes: Choose soft shoes two to three sizes smaller than your street shoe size. We recommend you fit your trad shoes one to two sizes under your street shoe size. Remember to factor in stretch. Unlined slip-lasted shoes tend to stretch about one full size. Lined shoes stretch about a half size. Remember: a well-fit comfortable shoe will work better than an ill-fitting tighter shoe. 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.

Rated 5 out of 5 by from The ultimate mountaineering boot. After wearing a few different insulated mountaineering boots including Vasque M-Possible and Lowa-Civetta, I was unhappy with the amount of movement my heel allowed and the resulting blisters. These were almost totally comfortable right off the shelf and after a single hike, were broken in enough. I then wore them on a 4 day climb of Mt Rainier's Kautz Glacier which includes a variety of terrain from snow/ice walking, scree slogging, ice climbing, glissading, etc. I found these boots to be PERFECT and I could not be happier. The price hurt a little bit but in the end, I would spend it again for the comfort my feet experienced. Thank you La Sportiva!

Rated 5 out of 5 by from Love these boots I rented these from my climbing group last year and loved them so much that I bought them for my next climb. I am a Women's 9.5-10 and I went with a 43, which is a full size larger than I normally wear. The women's version of these were too narrow but these fit like a glove. I wore them in Iceland this year for an ice climbing course and all of the other women and even men who could, had to borrow these bc they have the stiff bottom when they were climbing the ice wall. The way they fit me, is that they don't even need to be broken in and they are warm and respectively light.

Rated 5 out of 5 by from Better Than I Expected My boot options are very limited due to my shoe size. I was fortunate to pick these up on sale and with a gift card. I put about 10 trail miles on them before a Cascade climb. They performed better than I expected. I don't think there's much break in to be had with these so find out what you need to do to get your feet adapted to the boots (i.e.: calluses, tape, moleskin, etc...). I often put a patch of moleskin on my heel and I did this trip but I don't think I really needed to. The key feature for me is the locking eyelets before the ankle hooks. This lets you adjust the toe box for comfort, then cinch down your heel and ankle for stability. I have an ankle issue so this is important. They're waterproof and rock solid!

Rated 5 out of 5 by from Awesome Alpine Boot I bought these used this summer from a friend who never used them. I love Sportivas, my previous boots were the K 2 model which are falling apart after 60 or so long routes. These are similar but alot warmer. I used them this fall on Shastas Hotlum headwall doing the rock variation. Way better than plastics in vertical scree and they kept my feet warm down to about 10 F. This november we decided to try the south face of Lone Pine Peak. They were fairly comfortable on the hike in but i ended up using the for 75% of the route as it was quite cold. They work great on etriers and even free up to 5.7ish. I really only needed my slippers on the chimney and friction pitches. Incredible boots for alpine routes.

Rated 4 out of 5 by from Loved them on The Mountain I have size 13.5 feet, wide across the toes, yet not a high volume foot. These boots fit great (size 48)! I usually find boots that fit heel to toe, but most boots have too much volume even with extra socks/liners. Minimal break-in (walking up and down flights of stairs for a few months) then the first time they hit dirt/snow was the climb up Mt. Rainier. Wore them with a thin sock-liner and "mountaineering" thickness wool socks. Had to stop and re-lace only a few times. Zero blisters. I was especially worried about this due to my short break-in period, but not a single blister. Climb was early June, about a foot of snow dropped before our ascent, but feet were warm when moving (but not hot and my feet tend to over heat in tennis shoes!). Toes would get cold when we stopped for more than a few minutes, but would warm up quickly. Overall great boots, very comfortable, can't wait to use them again.

Rated 5 out of 5 by from Really good boots These boots are crazy expensive but worth every penny. Let's face it, when you're scaling a steep pitch of glacial ice at 11,000 ft, do you really wanna skimp on your boots? Your answer should be no. I've put my pair through the ringer for 2.5 years and they continue to perform great. Yeah, they get sweaty wet after climbing all day. Yeah they are kinda heavy. Yeah they look horrible. and Yeah, they are super comfortable, bomber stiff on the soles with enough flex in the ankle, warm enough for 3 season travel and take to crampons like a duck does water. I've tried 2 other brands of similarly technical boots and find these to be far and away the best. My only critical comment is to reiterate another reviewers feedback that the sole and upper seems to wear down really fast. The toe rubber on mine is pretty shredded. That said, I've spent weeks pounding the toes of these boots into the snow and ice to make steps so I cannot really complain about it.

Rated 5 out of 5 by from Great New England winter boot I picked up this boot in September and focused on breaking them in for the winter. These boots hike very well in snow. They frontpoint up ice nimbly and with confidance. I did notice the impact break at work as I stomped down Mt. Haystack. I wore them for about 30 miles until they were really broken in. I have found the lacing to be something I adjust a couple times to fine tune it: I have at times cutoff my toe circulation if I was not paying attention to the toebox lacing. I also have found that less sock works better with these; just a one layer expedition sock has kept me warm at O degrees at a long belay.

Rated 5 out of 5 by from Great Boot I bought these recently, anticipating several climbs this spring including Baker and Rainier. Had the opportunity to test them out in January on Mount Teneriffe winter summit. First impressions are good fit, warm, and did not produce any blisters with stock in sole, wool sock with liner, and only a taped heel. The last couple hours of the 9 hour trip I did start to develop a bit of a hotspot behind my toes, but no blisters. Paired the boots up with a pair of G10 Grivel crampons on the final 1500 feet to the summit, in knee to thigh deep snow. No problems at all. Overall I like the boot, and would highly recommend. It remains to see how warm they are at altitude but time will tell.

I am looking to invest in a set of durable hiking / mountaineering boots. Our first trip is to Kilimanjaro, with another to Rainier planned. Are these boots overkill for Kili?

Asked by: OverlordvI
I hope this isn't too late for your trip. But I would definitely not wear these boots on Kili. I hiked Kili via the Lemosho Route 3 years back. Kili is basically a hike (albeit a very high altitude hike). There's nothing on that hike that would require a mountaineering boot. And when you're hiking up 4,000 ft on the summit push, you'll be thankful not to have 4.5 lbs of boot on your feet. So even if you already own these, I wouldn't use them on Kili. Wear a pair of hiking boots instead. Your feet (and legs) will thank you.

Will these boots freeze and turn to icicles overnight, at negative 42 degrees, if they get wet during the day, or should I buy plastic ones?

Asked by: Neuropsych4Life
​These boots, along with most other boots, will freeze if they get wet in negative temperatures.

I am looking at purchasing these boots for general mountaineering in Colorado on the states fourteeners. What crampons would you recommend?

Asked by: pvfs2008
These boots are a great choice for compatibility with most style crampons (Hybrid, Step-in, and Strap-on), one of the easiest styles to put on with gloves is the Hybrid Style. The Petzl Sarken Leverlock Universal Crampons is an excellent choice for this style of crampon: We recommend also reading our Expert Advice article on How to Choose Crampons, to see which style works best for you.

How practical would these be to hike in winter conditions aside from mountaineering, such as winter backpacking?

Asked by: DC Climber
This boot is specially designed for mountaineering. Due to the robust materials and rigid flex profile, we do not suggest this boot for general winter hiking.
