    Ski to infinity, and maybe beyond.

    If you'd rather not spend your days in the backcountry with your feet crammed into an unforgiving race boot or floating around in a floppy-noodle rando boot, then get yourself the Scott Cosmos III Men's Alpine Touring Boot. Made of a marvelously stiff and light Grilamid plastic, the Cosmos II is a fairly aggressive boot, with a flex of 115 and a lean angle of 11.5 degrees. It also weighs just over three pounds, making it seriously competitive in the poundage department. But it's a more powerful boot than many of the other AT offerings out there, including Scott's slightly lighter Orbit II, thanks to the Grilamid and Scott's PowerLite reinforcing ribs that are placed through the shell and cuff. If you're a serious skier who spends serious time getting to serious lines, the Cosmos is one you don't want to miss.

    Don't get the impression that it's a one-dimensional downhill boot, either. It has 60 degrees of cuff rotation for easy ankle articulation, a rugged ski/walk switch, and an aluminum lean/lock bar that allows both the shell and the cuff to move freely for a more natural touring motion. Scott's also redesigned the tech fittings, making them Dynafit certified for an easy and solid connection with Dynafit tech bindings. We'd also be remiss to not mention the PWR Lite liner, which is seamless, fully thermo-moldable, and it has a reinforced tongue for plenty of smooth-flexing power.

    • Alpine touring boot built for long-distance tours
    • Wide 103mm last provides a comfortable, roomy fit
    • 115 flex is responsive yet forgiving during the descent
    • External walk mode delivers a rigid cuff-to-shell connection
    • Vibram rubber sole maintains solid traction on the bootpack
    • Micro adjustable buckles offer an adjustable fit
    • Item #SCO00Q6

    Best AT boots for wide feet!

    • Familiarity: I've used it several times

    I have very wide feet, and finding wide AT boots is extremely hard. These boots fit great, are light, and ski well. I couldn't ask for anything more. I also tried the Orbits. They would be a good option if you want to save every possible gram, but the Cosmos are great if you are going to ski hard.

    Killer boot

      After looking at boots for a while, i went with this Scott Cosmos. I have a wider foot, so the 103 last fit me really nicely. I love the lockout on the back. Its nice and sturdy, and there are no internal pieces to break. I have been using them with my Salomon Shift bindings and they work great. Nice range of motion and comfortable on the up hill, stiff and solid on the downhill. The liners are also very nice, with a drawstring on the front to keep them snug.

      • Familiarity: I've put it through the wringer

      Let me preface this review by stating that I was hesitant to purchase touring boots by Scott, a company I associated with exclusively downhill skiing before now. Then the boot fitter told me that Scott actually purchased Garmont and kept their boot engineers and production platform, and the result was the Cosmos III. What I first noticed was the simplicity in the design; no crazy bells and whistles or moving parts means less likelihood of things breaking in the backcountry, which for me is a huge asset. However I bought these over more widely-known touring boots (like Scarpa, etc) purely for fit. The wider last makes these super comfortable, and with a custom liner immediately fit my foot like a well used glove. Gone are the days of sore feet after 15 minutes on the skintrack. In are the days of hours of touring without any pain or hotspots. While I can't promise the same since all individuals are different, if you have a wider forefoot like me, these boots will do you well. I encourage you to try them on in a store before you by, just like any boots.

      Until last week I had only done a number of small side-country and easy backcountry days, and didn't feel comfortable writing a review until I tested them on some real terrain. After a trip to Japan and a summit of a very firm and technical Mt. Yotei, I can confirm that these boots kick ass. Not only were they great on the gradual approach and later steep sections of skinning, but they also did amazing bootpacking the last 700 vertical meters and ripping turns in the volcanic crater.

      What really did it for me though was the descent back down the side of Yotei. Imagine a 300 m field of a mixture of wind-drifted pow, sastrugi, and ice. These boots felt stable, comfortable, and were able to drive my ski perfectly down some extremely technical terrain. The same was not seen for my compatriot (probably because he wasn't wearing these boots), who took a gnarly fall and was forced to walk out. Overall I spent 13 and a bit hours in these boots skinning up and then skiing my buddy down, without any blisters or hotspots at all. The same could never have been said for my previous boots.

      All in all, these are fantastic boots that will work well overall for those with a wider forefoot, both on the skintrack, bootpack, or descent. Cosmos is a fitting name, since they will take you to the moon and back and you'll love them the whole way.

      Great Touring Boot!

      • Familiarity: I've used it several times

      I love the wide last on these boots. They feel great right out of the box and don't require the same breaking process as other narrower boots. I skied these several long days doing laps in the back country and no pain in my feet!

      The only downsides I see with these boots is the forward rotation when walking feels a bit restricted but there is enough to still feel okay on the skin track. I'm sure this is a compromise to help them ski better when locked down. And they feel pretty soft if you're used to a stiff alpine boot but they ski great and are solid choice even for in-resort skiing.

      Great Boot!

      • Familiarity: I've used it once or twice and have initial impressions

      I have only used these boots a handful of times but I am very impressed with their performance. The 103.5 last provides more than enough room for even the widest feet. The liners are super comfy and feel very durable. My only complaint is that these boots seem to be a bit soft for a 115 flex.

      Really Stellar Touring Boot

      • Familiarity: I've used it several times

      Checked these out from the Backcountry employee gear closet this weekend and I absolutely loved them. I took them up Mt Superior here in Utah and skied Suicide chute. My usual boots are the Scarpa Maestrale, and I think I like these Scotts even more than my Scarpas. Super high quality boot with the comfort to wear them all day long. No hot spots on my feet and no foot cramps while I skied. Really happy with these boots.

      Ski great

      • Familiarity: I've used it several times

      I tested these for a full day inbounds, including several boot packs.

      These boots strike an excellent balance between weight, comfort, and downhill performance. The stated flex of 125 feels accurate, and is quite progressive. The wide 103.5mm last didn't feel sloppy, but had plenty of room to keep my feet comfortable all day. The liners seem to be high quality and are quite substantial feeling (although not heavy) for a touring liner. My feet tend to run cold, but they were toasty warm in these all day.

      The skiing performance of these boots is truly impressive. They felt just like an alpine boot on the downhill. I didn't feel like I needed to hold back at all or adapt my style because I was skiing a touring boot. Having tried dozens of touring boots over the years, that's a rarity, and even more so for a boot that only weighs ~3lbs.

      In walk mode they have a decent range of motion. Being a four buckle boot with a traditional tongue, they don't have much forward flex like the two buckle tongue-less boots that have hit the market in recent seasons, but you do get quite a bit of rearward flexibility which really helps with a natural stride. It's easy to flip the walk mode switch and I like the simple but effective dual-locking mechanism.

      I would recommend these to folks that like to ski fast and/or in committing technical terrain in the backcountry and don't want to be held back by their boots. They'd also work well if you are primarily a backcountry skier, but want something that can be pressed into service on the odd lift serviced day (if you're using alpine bindings - just make sure they support a fully rockered, rubber AT sole - the Tyorlia AAATack 14 is a good option that does).

      Final note - the 103.5mm last is one of the widest on the market. Great for folks with wide feet or lots of weird bunions from years spent in ill-fitting boots. Those with very narrow feet might want to look elsewhere.

      Cosmos III - Out of this World!!

      • Familiarity: I've used it several times

      I put in a decent few miles on this boot. I typically ski a 100mm last boot. I thought I'd try this one out for the wide last to see if it made touring much better (not that touring was ever not awesome!).
      I could quickly tell that this boot was made well. Scott makes good gear, and you can tell with this boot. The 115 flex is pretty perfect for a small guy like me who still skis hard. I liked the feel and flex of this boot. I am a big fan of 4-buckle boots. They allow for more adjustability and provide higher performance in my opinion. The range of ankle motion is pretty good. You don't get the same movement range as a true skimo boot, but I had no problem getting up steep skin tracks in these and get way better performance. Skiing down these were a dream. They really felt like every other alpine boot I've had. After a few days in these I quickly realized that a 103.5mm last is too wide for me. I had a little too much movement than I would have preferred. I expected this might be the case given my narrow to middle width foot. My one gripe with this boot is the mesh lining on the boot liner. It doesn't integrate with ski socks very well and can cause some weird rubbing as the mesh tends to stick to your socks.
      Though this is not the boot to fit my specific foot, I still really enjoyed the days I put in using it and cannot recommend this enough to skiers who have a middle-wider width foot, ski hard and want a performance boot, and still want to be able to crush multiple laps a day on the skin track unencumbered by their gear.

      Stellar AT boot.

      • Familiarity: I've put it through the wringer

      I’ve been riding the Cosmos for three years now, and can’t imagine riding anything else. Right out of the box they fit my feet great, having a large toe box. I love the standard four buckle with a strap set up. This really allows you to dial in your boot at the top of the descent. The cosmos this year got upgraded with a burly walk/ski mode lever, instead of the standard pin. While this does make the boot a bit heavier from the two, I would not change this having broken a few of the pins on older models. They still come in at just a little over 3lbs per boot. The boot crushes descents with a 125 flex, this boot feels comfortable skiing pow to boilerplate ice. This is a very solid boot for someone who wants a nice light AT boot, but still wants the confidence to charge the slope on the descent.

      Great Boot but.....

      • Familiarity: I've used it several times

      Rode it for the first time this weekend at Jackson. Very comfortable right out of box (the wide last fit my foot well), no blistering during the entire day, and rides like a good and stiff resort boot. Overall impressed and couldn't wait to actually AT with it.

      1/18/2018 - Update: Finally getting to do some AT with the boot. Great boot. Light and comfortable. The overbuild "ski-mode" gives confidence. Can ride this boot with my wider skis and still feel in control and responsive.
