Rated 5 out of 5 by from This is the boot you need. I try not to be smug, It is not a noble trait but when we were given the order to quickly leave Camp 2 on Cho Oyu because of deteriorating weather, I couldn't help but feel a bit smug. As we sat in our tent, putting our boots on, I did the 1 pull lace thing and even in the o2 deprived air, had my boots on in 2 minutes Ok, i didn't time it but you know what I mean My partner on the other hand, was fiddling with laces, cursing and calling me names. The name calling, is like what I imagine men receive when women are in labor. It just wasn't called for..Anyways, great boots, i love them and permit me to feel a little smug about that.

Rated 5 out of 5 by from Probably the best mountaineering "Single Boot System" available. These boots are designed for very cold weather, high altitude climbing. I got them to use on Denali and, hopefully, Everest. They're expensive, but so are frostbitten toes, so it's a good investment. With these boots, you don't need overboots or gaiters (they actually use Kevlar material on the sides). The lacing system on both the inner and outer boot is unique and superfast, as is the outer zipper - you'll leave your climbing buddies in the dust getting ready in the morning! The boots are suprisingly lightweight and comfortable.,,,,You'll want to get at least one full size (and mabybe 1-1/2 sizes) larger than your normal shoe size.

Rated 4 out of 5 by from Great high altitude mountaineering boot. These boots are great, but just make sure your going into cold temperatures. I purchased these for an Aconcagua climb but wanted to break them in and get use to them prior to the trip. Took these bad boys up Mt. Baker and my feet have never sweated so much in my life. I could ring my socks out. Bottom line, your going to have warm feet. They are made stiff and in breaking them in, expect a little shin bang, it's a packaged deal. The only problem I have had with them thus far is one of the hooks on the booties broke. Good ole' moosejaw is taking care of me though and fixing the problem.

Rated 4 out of 5 by from Very warm and Great fit VERY warm boots that fit well right out of the box. These seem like just the ticket for a planned Spring trip to Denali. I was initially skeptical about the rather funky lacing system. Was worried that I would not be able to lace them up efficiently with gloves on, when it was cold, when I was tired, etc. However, after I spent a little time fine tuning the lacing system and did a few practice runs with the gloves on it seemed pretty much second nature - even easier since nothing to tie. They have a comfortable rocker so they are good to walk in and are also stiff enough to edge well. They wouldn't be my first choice for an ice climbing excursion but are more than adequate for the typ

Rated 5 out of 5 by from warm toes I bought the Olympus Mons for Aconcagua. Overkill (it's an 8000m boot)? Possibly. They are bulky and a bit heavy (relative to 6000m boots) and certainly expensive. Several times on the way up I wondered whether or not I’d spent too much money and was carrying too much weight up the mountain. On summit day, however, it became clear that I’d made a good choice. My toes were warm. The others on my team had toes ranging from cold to “if I don’t warm up my toes now, I’m going to get frostbite.” Warm toes are happy toes! My only complaint is their last. The manufacturer seems to think all mountaineers have very narrow feet. I typically wear a size 8 in US women’s sizes. Normally I'd size up a full size or so for mountaineering boots. However, in these, in order to fit in the width and depth, I had to order a 42.5, which I believe is the equivalent of a women’s US 10.5! That’s a bit much.

Rated 5 out of 5 by from Love the boot, Order 1.5-2 sizes larger I wear a size 45 in La Sportiva Nepal Evo and ordered a 46 in the Olympus Mons. The length seemed okay, but the width was a bit tight. The boots aren't much heavier than the Evos. Can't wait to get my new size and head out to check off a few more 14K peaks in CO.

Rated 5 out of 5 by from Great 8000 m boot This is the premier 8000 m boot. I have worn this boot to Antarctica and will be going next to Tibet. It's warm and comfortable and a must for high altitude [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Toasty Warm and Comfortable. Toasty warmth, super comfortable, easy to put on. It ties up with one gloved hand while everyone else is fumbling with their overboots or gaiters. Instant break-in. This is made for 100% glacier/snow use. Rubber sole is super soft so don't break it in on rocks or trail as you'll wear the rubber down prematurely. Get a size up that allows for expedition socks/liner and allow your feet to expand when pushing it. Awesome quality overall and it looks soooooooo cool too.

La Sportiva footwear is built and offered on European half sizes, which are smaller increments than US half sizes. This gives them four extra sizes per size run, and ultimately gives you a better fit.

Please review La Sportiva's size conversion chart above to help determine your ideal size. Below you will find additional information about how to fit and break in the different styles of La Sportiva footwear, which will also help guide you to the correct size.

• As a general rule soft shoes like climbing shoes require a tighter fit, or about two to three sizes smaller than your street shoe size.
• La Sportiva recommends you fit your trad climbing shoes one to two sizes under your street shoe size.
• La Sportiva offers a lot of lasts, and each offers a different fit and feel. Remember to factor in potential stretching.
• Unlined slip-lasted shoes tend to stretch a bit more than lined shoes, or about one full size.
• Lined shoes stretch about a half size.

• PERFORMANCE FIT - offers a high performance fit and a downturned last.
• TECH FIT - a more technical fit and a last with neutral profile.
• COMFORT FIT - a comfortable fit and a last with more volume and a neutral profile.

• Find your US Size in the guide above, then find the Euro Size conversion and add one half size.
• The ideal size holds your toes ever so slightly away from the front of the boot while the lacing system is snug across the top of your arch.
• If you can try to boots on beforehand, make sure you wear the same size and weight socks you would typically wear with the boots, and any orthotics or custom footbeds you use.
• It is ideal to fit boots later in the day since feet are prone to swell slightly as a day progresses.
• Wear your boots indoors only until you are confident about the fit.
• Your foot should feel snug (not tight) from the arch back into the heel pocket with just a minimum lift as you walk. If your heel lifts make sure the lacing is snug and not too loose.
• Your toes should NOT touch the front of the boot, but when you kick the toe into the floor, you should know where the front of the boot is. You want just enough room to wiggle your toes.
• If your toes or sides of your feet feel squished, most likely the width is too narrow and the boot will not work for you.
• If your toes touch the front of the boot, most likely it is too short and you need the next half size up.
• Make sure to keep all original packaging that came with your boots until you are sure that you are happy with your purchase.
