Description

Black Diamond's stiffest alpine touring boot, with four buckles for power and a pivoting cuff for buttery-smooth touring.

Men take note: Black Diamond's Quadrant Alpine Touring Boot offers the lightweight chassis of a touring boot and the power and precision of a freeride boot all in one. Precise and stiff enough for long, high-speed turns, this AT boot is a tool for seasoned backcountry skiers who want to take on steep mountains and skin-accessed terrain without sacrificing downhill performance. In walk mode, you're treated to a massive 40 degrees of buttery-smooth cuff flex and in ski mode, the cuff locks securely into place against the shell of the boot for rock-solid shredding. The Quadrant is the stiffest of Black Diamond's alpine touring boots and it's built for technical ascents and neck-snapping speeds.

  • Triax pivot frame is a touring-focused frame design that offers alpine-style power transfer and smooth, natural striding motion when you're touring
  • 120-rated flex index provides enough stiffness to precisely control your skis and just enough forgiveness to make long days of touring easier on your foot
  • Efficient Fit AT Light liner is stiff and lightweight, designed specifically for touring
  • V-shaped last has a 103mm toebox to give your toes room to move and allow ample circulation for warmth
  • Truelasted liner fits your foot right out of the box or it can be easily thermomolded for a truly custom fit
  • Liner secures with the Boa closure system that you can tighten or loosen with the spin of a dial
  • Liner also features an antimicrobial treatment to stop funky odors, a smooth interior finish so it's easy to slide your foot inside, and a multi-density Achilles' pad insert
  • Four-buckle design offers the traditional security and power transfer of an alpine boot balanced with the free-flexing cuff technology of Black Diamond's Pivoting Cuff
  • Buckle closeout dents have a hooked shape that locks the QuickWire buckles securely in place once the buckle is flipped down
  • Pivoting cuff design offers resistance-free movement in tour mode so you get a whopping 40-degree range of motion with each step: 20 degrees back and 20 degrees forward
  • Pivoting cuff locks into the edge of the instep cuff in ski mode, pressuring against the boot shell for stiffness and power
  • In walk mode, the pivoting cuff naturally slides up and out of the way of your instep buckle to allow the boot to flex further forward
  • Rubber outsole has a rockered shape that dramatically increases traction and allows for the most natural foot roll when you're hiking or bootpacking
  • Tech inserts give you the option to use this boots with Tech-style touring binders

I Love this boot

  • Familiarity: I've put it through the wringer

I love this boot. the 120 flex allows for great power on the down and the Range of Motion for the up is killer. with a few modifications to the cuff you can increase this ROM. The stock liners are not the most comfortable but slipping in a intuition pro tour and their like slippers that charge. The tech binding capability is great because I have Marker Free tours that I use with this boot along with Dynafit Vertical FT. Love. This. Boot.

Hi I have quite a wide foot and like everything I can see about these boots online, but cannot find any information pertaining to the width of the boot. I often find my outer foot (6th toe area) extremely cramped and am hoping this boot will cater to a wider foot and am looking for a 29cm (US 12)?

Best Answer Responded on

The last width on this boot is 103mm. Thats about as wide as ski boots get. If you are looking for a boot to accommodate wide feet, this is definitely a solid choice. Enjoy!

Responded on

Hi Jason,
Joey is correct: very wide boot.
I have absurdly wide Flintstone feet, and this is the cat's meow for me.

Responded on

I'll put down a third thought.. I have the Slants which are a few bumps down, but the sizes are all the same. Definitely a good fit for wider feet.. Plenty of room right at the ball of the foot.

Nice and honest review.
Why I think it's honest ? Because I own these and everything he says matches my opinion.

Canting and Forward Lean.

  • Familiarity: I've put it through the wringer

Folks, I adjusted my boots just a minute ago and I just have to share with you the experience....
OK, So I tried and thermo-fitted the boots at local shop and decided to purchase them....
At home )of course) I was trying several times and I felt something was missing.....
I didn't feel perfectly comfortable wearing the boots and actually was even a little worried if I will make it with those boots....
When I was wearing them, I felt the boots were kinda over-powering me leaning my body too much forward and also my knees were pulled inside wile standing on flat floor....So I did the adjustments of forward lean and canting....People, seriously - it's like totally different boot. Now I it is sooo good to wear them and - it will probably sound a little strange, but - even my feet feels a lot better in the liner wearing the boots....
So the bottom line:
Please, Please adjust your boots to your personal needs....do the forward lean and canting adjustements.....
Below is the link to how to do it...It's very simple....Just grab that freaking HEX Key and do it.....
Just a bonus - the video shows that you should take the liners out....well I forgot about it and did the adjustments with the liners inside and it worked just as fine.
Good luck.

Just a Fit Review

  • Familiarity: I returned this product before using it

I have a size 8.5-9 foot (street shoes) (26 Mondo) with a wide forefoot, skinny heel, high instep, massive arch, and skinny thighs and ankles, and I usually run a 300-307 BSL. I've been sizing down a 25/25.5 and figured that these boots would do the trick.

The 25.5 size (25 shell) left less than a finger width (10mm wide Sharpie) when shell sizing, which left little wiggle room for the toes when kicking or the space taken up by custom insoles (in my judgement). The liner felt tight out of the shell (not molded) and in the shell there was more than a 'moderate' amount of pressure on my big toes. Good news, the boot volume was right where I felt it should have been and the cuff height was decent. Here's the cliche at work: it's always easier to make a small boot larger...etc, etc. While I prescribed to this when I raced, now that I spend long mornings or days touring, a little extra room in the toe box is a welcome relief and if the rest of the fit is right, it takes nothing away from ski control. That said, I decided to pass on these boots based on the fit for MY foot.

Side note: after comparing the overall build and features to the Scarpa Maestrale and Maestrale RS, I was much more impressed by the liner, walk/ski mechanism, and buckle placement and construction on the Scarpa boots. The BD *felt* (subjective) a little cheaper than the Scarpa's. Had the fit been right this wouldn't have stopped me from choosing the BD's but it did give me a moment of pause.

Four stars because I'm not going to moderately rate a boot I haven't actually skied.

Disclaimer: boot fitting is an art and there are more variables to getting the right fit than anyone would like to admit. This is an anecdotal, tried-on-in-the-house review. Take it with a grain of salt.

Responded on

I didn't have a chance to try on a 26-26.5 size in this same boot. Doubtless it would have given me additional space, but I've found that a 26 shell leaves a little too much space. Boot sizing is a game of millimeters and preferences, unfortunately.

Responded on

Austin - You might want to try the 26 shell because I believe it has a 300 mm bsl, which is right in the middle of your typical 25 and 26 in terms of BSL. Like you said its a game of millimeters. I too find a 25 a bit small and a 26 a touch big so generally go for size 26 boots that are on the smaller side as far as bsl like this boot.

Posted on

Will these boots work with a Marker Tour F10 AT Binding or other type of Marker AT binding, or will i need to get some sort of Dynafit style to piece binding?

Responded on

These will work with the any AT binding. But you will also have the option of using tech bindings.

Posted on

I'm looking at getting AT boots this fall & currently have been on Raichle/Full Tilt boots for a bunch of seasons. How does boot volume compare to the alpine boots I'm currently on???

Best Answer Responded on

The boot volume on these should be greater than the full tilt. I'm basing this primarily on wearing Konflicts previously (and comparing them to most 2 piece AT designs) as well as this boot's last width of 103mm compared to the Full Tilts last width of 99mm.

Responded on

I ski in bounds with the full tilts and use the Dalbello AT boots, they have a similar feel to the full tilt just a little softer flex.

Does anyone happen to know if there is any...

Posted on

Does anyone happen to know if there is any difference in the fit or attributes of the new model vs. the previous one? (The yellow & green model) Thanks!

Responded on

I was just buying them today and my friend has the previous model and said the liner in new model is better....
Another thing I've gone through is that the new model is probably the stiffest BD boot......so might be stiffer than the previous......Hope that help :)

Responded on

I tried the previous year, loved the boot but the liner was terrible- packed out like crazy after about 20 days. Exchanged them for the new version, and the liners have been solid- probably about 60 days on them so far and still going strong.

Didn't really notice any other significant changes between the two models.

Great Boots

I use these for both in bounds and backcountry skiing. They are pretty comfortable for going uphill and down. The only time I notice these don't have the same stiffness as a regular alpine boot is on moguls but I didn't buy the setup I have to mess with that junk.

Incredible boot

  • Familiarity: I've used it several times

This weekend I toured 17 miles in one day in these boots, skinning, skiing, and bootpacking, and came out without a single sore or blister. These boots are incredibly lightweight and comfortable, have great flexibility in tour mode, and are plenty stiff for downhill descents, to the point where they work perfectly as a resort boot as well. I couldn't be happier with this boot.

Incredible boot

Light and Lame

  • Familiarity: I've put it through the wringer

I owned these boots and sold them.
The plus is that they are stiff and have a lot of Range of Motion in the walk mode. They ski pretty well.
The Bad...for me
The liners are a piece of junk, just figure that those will be sold right away and replaced.
The foot buckles go right over and press down over the nerve in your foot that will make them numb and colder.
They need to redo the liner and pull the plastic over the top of the foot more with a bulge so your feet don't fall asleep.

Responded on

Did you mold the liners properly (or at all)? Those all sound like problems from a bad fitting.

Responded on

Oh yes molded the liners, but I'm not the only person who feels that the BD liners are an inadequate liner.

Responded on

I bought these and immediately swapped out the liner - the heal cup was way too narrow for me. Wanted the boots even though I had to go to the extra expense of new liners because the range of motion makes for so much easier skinning. Did a few days in-bounds on volkl gotamas and was surprised how well they coped with the weight and stiffness of that ski. Will be doing the Haute Route in these next season - my old touring boots were garment adrenaline - the quadrants will I think make the longer up days a lot more fun.

Responded on

After 1 season, I have had similar experiences with foot numbness using these boots and that is following liner molding and shell customization. I may look to replacing the liner this season, but I'm not sure to which liner to change. Any recommendations?

Responded on

Wish I could have a suggestion for you on this, but even the aftermarket Intuition overlaps that I put in did not work for me and resulted in numb feet. So I sold the boot...

Responded on

I had these, got new liners, had a few spots punched out and consistently experienced numbness and freezing toes due to cutting off circulation, so it sounds like we all had similar experiences. These were also more sloppy inbounds than I would have expected given the flex. I ended up with Scarpa Maestrale RS...

Responded on

Same here... The blood circulation in my forefoot was just off ;)
So I removed the footbeds but then I had too much space in the boots so I went to the local shop and made custom footbeds......Helped just a little bit but still far from what we desire.... So in my feet's case, there is no place for ANY footbeds whatsoever......
Will try without footbeds wearing thicker socks and see how this will work....
Will let you guys know....

Responded on

After skiing the stock liner for a while, I started looking for a replacement. Intuition seemed the right call, so I looked for Pro Tours. They were out, so I went with the Dreamliner, and while I wouldn't say that the ankle flexibility the same while touring, the increased stiffness on the down was really, really nice.

The cool thing with the Dreamliner (I grabbed the High Volume) is that it comes with two foam shims for under the footbed. You can pull them out and use your own footbeds or mold them as a footbed. Or, if you're using them for day tours, but then want to do some Alaskan expedition, take out a shim to account for foot swelling at elevation and wearing thicker socks.

That'd be my call for a replacement.

Will these work with both Dynafits and my current alpine set-up (Marker Griffons)?

Best Answer Responded on

Hey Maximus Cole,

The Black Diamond Quadrant boots will not fit any DIN ISO bindings due to their toe and heel lugs not being prominent enough for a DIN ISO rating. The AFD system on the Duke or Baron is different so it will fit there, but not on straight alpine bindings.

Responded on

Do not listen to JohP10023...
I am a ski tech and these boots WILL NOT work with a standard alpine binder. They will work with alpine touring bindings but not standard alpine bindings.
