    Crosses the line between snowboarding and mountaineering.

    With integrated heel welts, a leather upper, insanely grippy Vibram outsole, and a bevy of other features, the K2 Snowboards Men's Aspect Snowboard Boot is designed to keep your feet happy and secure through long days spent in the backcountry. Unlike any other boot out there, the Aspect is designed to breeze through the most technical situations, when you've got your crampons on, axe in hand, and you're about to take on the last pitch for untouched big-mountain glory.

    A rugged, waterproof leather upper and traditional laces make up the exterior of the Aspect for reliable protection and a fit that you dial the old-fashioned way, while the thermo-moldable Intuition Pro Foam 3D liner with a Boa Conda lacing system conforms to the natural shape of your foot and locks you in quickly without having to mess with internal laces. To further overall stiffness, response, and support, the ENDO urethane skeleton construction provides a precise, engineered flex that stays consistent from day one through the life of the boot, while adding a lively, energetic feel that reduces fatigue on demanding days.

    Internal and external J-bars lock down your heel to help prevent heel lift when dialing your turns in no-fall zones is of the utmost importance, and the 3D-formed dual density EVA footbed absorbs harsh impacts from dropping huge cliffs and navigating choppy terrain. Specifically designed for boarders who mountaineer to access their lines, the Vibram Mountaineer rubber outsole has a traditional lug design and is crampon-compatible to safely get you to the top of technical ascents.

    Initial impressions are great!

      It's great to see the improvements in technology as related to splitboarding! I finally felt it was time to upgrade my old malamutes to something designed with crampons in mind.

      I read about the other crampon compatible boots and these seemed to fit my style the best, I didn't want anything quite as stiff as the Fitwell's.

      The K2 Aspects are still stiff, and just the right amount. Usually I wear an 8.5 boot but I chose the 8.0 in these due to other reviews and some local shops who had tried them on, the 8.0 is perfect! Just got the liners heat molded today too.

      I love the beefy sole and the Boa liners. I've never been a fan of traditional laces on snowboard boots but between the laces and the power strap at the top I don't mind it at all.

      I use Karakoram bindings so I'm a little worried from what a previous user mentioned about them not fitting well. I have the Karakoram Prime's and they do have some adjustability in the heel cup so hopefully I can get them to work, I'll update my review after I'm able to field test these.

      Haven't chosen a crampon for these either.

      Overall, I'm stoked about these, and they are WAY easier to get on and off than my old Malamutes, they were kinda a pain IMO.

      Beware if you have karakorams

        These boots are 100% unusable with karakoram bindings. The way K2 makes their boots they have very unusual heels that stick WAY WAY out and the heels suck so far back into the heel cups that there's an insane amount of heel overhang that can't be eliminated with any binding adjustments. I had another buddy have the same problem with these boots. I doubt they're much better with sparks either. It's a design flaw with all K2 boots. I had T1's and they barely fit into burton resort bindings because of the heel. I love the fit of K2 boots but I'm done buying them until they change their design.

        pretty rad

        • Familiarity: I've used it several times

        gave these as a gift to a buddy of mine. here is his feedback:
        These boots are burly and made for split-board mountaineering. Between the vibram (mountaineering sole) and crampon compatibility heal piece, these boots will get you to the peak of any mountain. They are surprising light for how beefy they look as well. And have an average footprint compared to other boots. They are sized a little big so I would recommend a half size smaller than normal. The boa system is great for touring to lock your heal in place ( say good by to heal blisters) The main difference I noticed with these boots compared to a normal snowboard boot while touring is the ability to hold an edge on a off piste skin track. These boots are stiff and rip going down the mountain and feel like a normal snowboard boot. They are good to go right out of the box.
