Black Diamond Prime Alpine Touring Boot -

Sacrifice nothing when you pull on the Black Diamond Men's Prime Alpine Touring Boot before a marathon ski tour or dawn-patrol powder mission. This lightweight boot offers power, precision, and comfort in an AT package that's just as comfortable and warm as your alpine boot. In walk mode, you're treated to 40 degrees of buttery-smooth cuff flex to keep your stride natural on the skin track, and in ski mode, the cuff locks into place against the boot shell so you lose nothing in the way of performance. Push this boot into technical descents worthy of a freeride boot and tackle ascents that would otherwise demand a too-light, minimalist AT boot—the Prime takes both in stride.

Fit:

  • Truelasted liner fits your foot right out of the box or it can be easily thermomolded for a truly custom fit
  • Efficient Fit AT Light Liner With BOA Closure System
  • Efficient Fit AT Light liner is stiff and lightweight, designed specifically for touring

Padding:

  • 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

Frame:

  • Triax pivot frame is a touring-focused frame design that offers alpine-style power transfer and smooth, natural striding motion when you're touring
  • Triax Pivot Frame With 110 Flex

Insulation:

  • Buckle closeout dents have a hooked shape that locks the QuickWire buckles securely in place once the buckle is flipped down

Sizing:

  • Black Diamonds Lightest Touring Boot 3.28kg/7lbs4oz (Size 27)

Outsole:

  • Rockered Rubber Outsole With Integrated Tech Inserts.

Traction and Grip:

  • Rubber outsole has a rockered shape that dramatically increases traction and allows for the most natural foot roll when you're hiking or bootpacking

Features:

  • 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
  • 110-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
  • 3 Buckle Alpine Touring Boot With 4 Buckle Performance
  • V-shaped last has a 103mm toebox to give your toes room to move and allow ample circulation for warmth
  • Tech inserts give you the option to use this boot with Tech-style touring binders
  • Liner secures with the Boa closure system that you can tighten or loosen with the spin of a dial
  • Pivoting cuff locks into the edge of the instep cuff in ski mode, pressuring against the boot shell for stiffness and power
  • Pivoting cuff design offers resistance-free movement in tour mode so you get a whopping 40-degree range of motion with each step: 20degrees back and 20 degrees forward
  • Three-buckle design keeps your foot secure and ensures power transfer when skiing without hampering the free-flexing design of the boot when you're in tour mode

Positive Reviews:

I really like this boot. It is very comfortable on the skin track with plenty of flex. Both cuff buckles, when unratcheted have hook-shaped catches for the bails so they dont pop open. This makes transitioning from climb to descent very fast and efficient. After you de-skin, lock your heel, lock your ankle, flip the two ratcheting buckles, repeat on the other foot and go. The liners seem fairly warm in weather down to 0 deg. F but not something that, by themselves will keep your feet toasty on sub zero days. One thing I especially liked about the liners was the use of what appears to be at least 3 if not 4 kinds of foam to achieve a great fit with flex for ascending, insulation under foot and some intuition foam for final shaping. And, the boa system remains a favorite of mine even though this boot has dental floss-looking boa laces instead of super thin cables. I have low volume feet and found the fit to be pretty good but they probably fit mid volume feet best. The length seems to be just a tad on the short side converting US running shoe sizes to mondo on the BD sizing chart. They appear to be pretty decent easy to mid grade ice climbing boots too from my back yard simulations. So, overall, a well put together backcountry AT boot. They ski well in the area too by the way but if you are mostly skiing challenging terrain you probably would want a higher boot there.
One final thing- the price. I think you get a lot of boot for the money. There are lighter backcountry boots out there but you save 2 kg for $200 more boot. Im just sayin... These boots from what Ive seen (never owned any though) dont seem to ski any better but of course, you save 2 kg on the uphill. For price-conscious skiers I think the Prime is a very good choice.

I had the older version of these boots, but I'm sure BD has only improved on them. They are a good boot for the beginner backcountry skier. I took them to Southern Alaska for a 24-day tour, and they were great on ascents and in camp (warm, great walk mode, very comfortable, super lightweight); however, the descents were not as impressive. I wouldn't feel comfortable doing, and I actively avoided doing lines that were too extreme; they simply don't have the response I would want to feel comfortable navigating through all-or-nothing chutes, which is too bad.
I have a pretty fat foot, so I like the BD fit, the BOA lacing system is awesome because you can tighten them up for ascent and then even more at the top if need be, and the heat-mold liners are great if you do them (I considered intuition liners, but didn't feel the need after my trial runs in the Sawtooths). I still use them after putting them through a considerable amount of wear of the mountaineering variety, and I got them on sale for 4 hundo, so they were definitely worth the price. Overall, I've warmed up to them for the intermediate level backcountry terrain and more advanced mountaineering that I do. If you want something more serious and want to be aggressive downhill, go with a higher flex definitely. I would recommend them with reservations.

I use thes eboots inbounds and out. Work Ski patrol in them all day long and never a complaint. I do use an older intuition liner...just couldn't get the liner to work for me. But didn't try very hard. Wish they had a swapable sole but I think that is one of the things that makes them so light.
Great walk mode and plenty of traction for scrambling.
I do have a big foot so if you have small feet you probably will be un happy. Go to a boot fitter and find somehting that fits.

Negative Reviews:

these things didnt last a season of touring. cracked both bootboards under the arch, 2 wire buckles failed, soles are torn up from walking on rock, super roomy/unresponsive (i have a pretty normal foot), pebax shell has some serious gouges/ is just plain beat up, flex is sloppy non-progressive and harsh at the end, locked open buckles will shred your pants, boa liners blow, and the shell around the canting pivot has ovaled.
so if you are still considering these boots then read on: amazing tour mode, light, roomy (if you have giant feet), warm (but just do yourself a favor and get intuition liners), cheap (you get what you pay for), good traction, and i would be stretching to find another pro.
unless you have high volume feet just dont even bother

It is a work horse. But paln on buying a new liner. Teh liners are pretty bad fir wise. I have been told they are simply too small for the shell. Mine were for sure. But great skiing boot. Heavy and doesn't walk well by comparison. It si a boot I would only buy on sale and use if you worked on the hill.

Dane at Backcountry.com on 11/04/2013

I tried to like these, but in the end they were to wide and mushy. I have a fairly wide forefoot, but these boots were just too wide. They had no 'snow feel' at all and were just too sloppy when skiing. They do tour well and have good range of motion. Went to the scarpa maestrale and am much happier.

Neutral Reviews:

boa liner: actually pretty neat. no complaints. but, also totally unnecessary. assuming you care about comfort while touring. i've heard that when they break, they are very difficult to field repair.
weight: slightly outdated for a 3-buckle boot. i'd be more inclined to go to a TLT or something similar, which I believe would perform just as well.
buckles: solid. i really like them.
walk more: not super easy to trigger all the time, but usually works just fine.
on/off: easy to put on and off with pull tabs and the liner.
walkability: there're better out there, but there are also much worse out there.
soles: great, durable, grippy vibram.
I very much see these boots as filling an important void between your first pair of touring boots (which are bound to be some ridiculous 5-buckle heavy monsters to use with your Dukes or whatever), and your third pair of touring boots (which are going to be lightweight, proper, and actually a good decision). In that vein, I would put these in the same category as the Dalbello Sherpa.
Oh yeah, and I've spent a week park skiing with these things in regular DIN bindings. That may or may not have been a mistake.
Overall, they're great boots. Really. But, at the same time, they kinda suck.
I would recommend them to all of my friends using the BD Quadrants or whatever the other heavy boots are called. But to someone using a Dynafit or Scarpa boot, I'd probably recommend that they keep what they have.
These walk better than they ski. And I rarely object to that concept. But given their weight, I'd expect the opposite.

Brody at Backcountry.com on 11/22/2013

It's a great light weight boot. I used this boot for about a season and a half. But for some reason these things just won't stop rubbing my inner ankle bones. After long tours my ankles are actually bleeding. I thought after a while they'd get broken in. The only thing breaking down are my ankles. I'm going to have to return them for a different boot.
