Mid Stiff - Versatile and responsive. A mid-stiff boot brings a touch more control to fast turns, take-offs and landings – perfect for confident all-mountain riders.
CLOSURE SYSTEM
Dual BOA® technology provides quick, precise lace adjustments via two independent dials. Each controls a distinct boot zone, delivering a custom fit in seconds.
BOA® Fit System
Ready for anything, designed to withstand. The bombproof BOA® H4 Coiler is built for the most demanding riders and resists impacts from park to pow. Its efficient mechanism rapidly takes up lace slack, increasing speed of entry.
HEEL LOCK
Awesome foot hold that starts right inside the liner, with 3D molded material and J-bars around the ankle. Minimal movement, maximum control.
OUTSOLE
Constructed from a single piece of bombproof and lightweight EVA, our Gravity+ outsole delivers great cushioning underfoot. The tread pattern is inspired by snowcat tracks, with a rubber section at the toe for reliable grip in icy conditions.
LINER
The Silver liner can be heat molded for a custom fit and features a Custom Flex Zone at the toes, 8mm PE foam, and added PU support. A separate cuff connected to the shell ensures easy entry, while touch fasteners on the tongue secure the fit.
LINER CLOSURE
Pull the inner laces to tighten a shell-mounted harness. Touch fastener secures the tongue.
INSOLE
Anatomically designed to cradle your foot and constructed from two densities of EVA, with firmer material supporting the heel cup and arch. A fleece-lined footbed with silicone top-print keeps you warm and secure.
FEATURES
The industry standard in speed lacing systems. Micro-adjustable for a precise fit and engineered to perform in the toughest conditions.
Our 3D Toebox minimizes extra layers and seams around the forefoot, improving water resistance and durability. The streamlined design also makes it easier to slide your boot in and out of the binding.
Our asymmetric 3D Molded Tongue features a sharper curve on the medial side to match your natural forefoot shape. This design minimizes pressure points and delivers more balanced comfort and support than a traditional straight tongue.
A unique asymmetrical design co-developed with BOA® for balanced support and flex. The tongue's lace guides are positioned over flatter forefoot areas for even closure and reduced pressure points. Enhanced medial arch support fights foot fatigue.
The upper boot cuff is asymmetrically connected to the lower boot, allowing the ankle to flex naturally and providing great support without shell distortion.
Made from advanced memory foam, our moldable liners adapt to your foot shape over time or can be heated in store for an instant, personalized fit. Experience zero pressure points and maximum comfort.
A durable section at the back of the boot that protects it from wear. Our unique Transition Zone™ means the rubber is bonded smoothly to the outsole with no ridges, minimizing any snags when you enter or exit your bindings.

Thank you for your understanding.
I need little bit stiffer boots than my previous flex 5 so I start looking for a new boots. I rented Nidecker boots when I snowboarding in Zao Onsen early this year in Japan and had great experience during whole time. It’s kind hard recall which model boots I rented but I watched couple YouTube review and all ppl said Altai is comfort. I know 9.5 kind fit me since this is the same size I had during rental. I expected It will be a little bit tight than my rental boots since it new but it just totally perfect in the first time I wear it. I will highly recommend this amazing comfort boot.
This boot liners Closing pieces does not allow me to close firmly as they hit each other

Just finished a season in these. SO comfortable every time. Love everything about these.
Hey Carolyn,
A full season with zero comfort issues—that’s what we love to hear! Glad the Altais were the perfect fit for you. Keep shredding!

Very light and comfortable boots, love the dual boa.
Thanks for the great feedback, Anna!
Glad to hear the Altai Women boots are hitting the mark for you. The dual BOA system and lightweight feel are definitely designed to keep things comfortable and responsive on the mountain.

Excellent boot. Firm, but responsive and comfortable. The dual BOA is excellent. Fit my EE feet in my size, which is nice. Ride all day with these.
Super
Wore the boots twice, for 2 hrs., around the house before going out on the hill.
First day snowboarded for 8hrs.
Boots where very comfortable and warm (temp. outside was -8C).
At age 57 these boots where just the right stiffness for me.
I am an aggressive carving snowboarder and a Ski Patroller.
Boots where used with the Nidecker Supermatic.
Definitely recommend.

super
It fits perfectly and very comfortably
It was a risk to order boots without trying them on. But I tried them at home, and they felt good. Of course, everything will be clear on the slope, but so far I like them.
Hi Riamonds!

Fit 10/10 for my wide feet.
Will seehow long it lasts. So far all good.
Bought for my daughter..
Looked nice and seemed like decent quality
Love these boots! I am still relatively beginner at snowboarding but have been looking for stiffer boots that can hold my heel down. WOW what a difference these make from softer boots!!! My turns are much easier and these boots are much more responsive! I could not recommend enough, even if youre still learning
Hey GM,
That is awesome to hear that you are loving the new boots and noticing a big difference in performance! Thank you so much for taking the time to share your feedback and for the recommendation.

Great boot for the price. I used to ride the burton Imperial, this boot feels almost identical plus you get boa for a price that is significantly less than what burton charges. I would say it runs middle of the road on width. Mid stiff flex is accurate. Enough support for the big jump line but enough flex to play.
Very good
As a beginner who has a 4 hour drive to the closest resort, I was looking for something quality but affordable. This boot was comfortable and durable enough to take my beginner�s falls all day. These work fine with the Supermatic step-in bindings.
Well constructed, seem durable and after a few days of riding they broke in well. I like the stiffness, very responsive with edge control. Happy with this purchase.
Really nice fit and quality i would like them more tight to support my feet better (feel a bit loose even though I tight them hard
Comfy. Good response. Works great with my supermatics
Solid boots, I've ridden a half-dozen different days in them and am so far pretty pleased. The dual-BOA is nice for dialing in your fit (pun intended). They are a nice amount of stiffness to be responsive but still comfortable for long wear. Only critique is that they seem to run a little small, as I ordered my regular shoe size and my toes are pretty cramped. I think if I were a half size up, they'd be perfect.
Super responsive, very comfortable right out of the box. Highly recommend!
I'm a snowboard instructor and these boots have been great for all riding styles. They fit my feet nicely, the double boa is accommodating for a high high-top of my foot and I can imagine they would be a good fit for most people.
Boots for one season!
1) very soft, do not match the declared hardness (is not 7/10) maximum stiffness= 5/10!!!
2) very weak materials, threads, seams (The threads were torn, the seams came apart, the leather was frayed. see attached photos)
3) Boots increased in size after 3 months of use once or twice a week (in small mountains 120 meters high)
?o summarize: not reliable, poor quality. The quality does not match the sports equipment. Mountains are places of increased danger and equipment must be of proper quality!!! A person�s life can depend on the quality of equipment!
Great boots. I have a wider foot. Straight out of the box these boots are comfortable. They match up perfectly with my supermatic bindings
I was a little reluctant ordering online and not trying on, but these are very comfortable and very supportive boots. I needed a boot that worked with the Supermatic bindings, as they tore my other boots apart. These are great so far, but I haven�t really put them to the test. All good so far!
Comfort, perfect fit, responsive and great design!
Great binding. Should highly recommend them to any ski patrol or instructor
Got mine today, and as already written, fits out of the box and super comfy, feels like walking on clouds. Next step is in the snow on coming weekend, and then supermatic, when its available in XL, maybe in a cool grey color ? thanks nidecker:-)
