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 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.

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

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.

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

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

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.

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

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.

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.
