I LOVE these boots

  • Gender: Male
  • Familiarity: I've used it several times

So I bought a used pair of these that ended up being too big, which bummed me out because I really dug them other than their being too big. So when they went on sale at BC I picked up another pair and pawn the old ones off to a buddy who has these club-shaped, massive feet. Anyway, out of the box these boots are CRAZY tight. I'm talkin' get them off as fast as you can tight. But the Black Diamond guy assured me they were right. I bought them and got them cooked at a BD dealer and I cannot even describe how awesome the fit it now. Seriously unreal. So...get the right fit no matter what they feel like out of the box, get them cooked (can't stress enough that these liners need to be cooked) and enjoy the best boots you've ever had.

Fresh out the box

I just got these for the up coming season as I continue to build up my touring set up. First thing I noted when I opened the box: these boots are stupid light. I know much lighter boots exist on the market, but factoring in the price and the versatility of the Primes against the competition, I have to say these are a great deal.

One thing I would mention is that the toe box is a bit snug on these boots. For alpine that would be fine, but for touring I prefer just a bit of room so I am not jammed in the front of the boot during walk mode. My advice, buy two sizes, your go-to size and a half or full size up, then return the one that doesn't fit.

Now all I need is snow.

I've been using Scarpa Denali, size 26, and it's finally time to replace them. How do the Prime's compare in size and fit to my old boots?

Responded on

BD boots typically run wider and higher volume than Scarpa, though this may depend on how old your Denalis are. Garmont, Scarpa and Dynafit are more likely to match.

How do these boots with wide feet? I'm using Garmont Mega Rides right now and there a bit narrow for my feet.

Best Answer Responded on

Hey rothman.da1664268,

Thanks for the question. The Black Diamond Prime Alpine Touring Boot - Men's would be slightly wider than the Garmont Mega-Ride AT boots as they have a 103mm last width. Only the Scarpa Typhoon would be wider at a 104mm last width and have the same 110 flex, but the Black Diamond has a bit more range of motion in walk mode. I would say to go with the Prime AT boots as you are only slightly narrow in the Mega-Ride boots and the Prime does a great job of balancing uphill with downhill performance.

OK, now time for a stupid question. Do "Touring" boots fit in standard alpine bindings? I'm upgrading my equipment one piece at a time and want to make sure that as I head toward a touring setup, that I can still use my downhill skis and bindings.

Best Answer Responded on

AT boots usually have some rocker to the soles to make walking easier. These have that feature. Alpine boots have flat soles and alpine bindings are designed to work with those flat soles.

So, no. They won't work with your alpine bindings.

Responded on

Boots like the BD Method or Factor, or Dynafit Titan, are touring boots that come with interchangeable sole blocks for both AT and DIN bindings. Technica also makes some similar boots, as well as other companies I'm sure. These are all on the stiffer side of AT boots, which is good if you will be using in-bounds as well.

Posted on

Has anyone out there had there foot in both the Factor 110 and the Prime? I've had my foot in the Prime and was wondering about if there was a noticable sizing difference between the two. In the Prime, the 26.5 was TIGHT, so I'm wondering if the Factor 110 would fit the same. Thanks!

Responded on

I've never tried the Factor 110, but have worn both the Method (discontinued) and the Prime and felt that the sizing was spot on the same.

So, I basically use the AT equipment as an exercise modality and then hope to downhill for the rest of the day on powder/groomers. The boots are very comfortable and I'm considering the Volkl Mantras with Dynafit bindings. Thoughts?? Steve

Responded on

If you really ski more than you tour, then you might look at the Dynafit Titan, which is a beefier boot. On the other hand, if these are comfortable, and seem stiff enough, that is half the battle. The Mantra is a great choice, but if you are really one up and done, perhaps consider a Marker Duke or Barron binding. A weight penalty, but beefier and more downhill oriented than the Dynafit. And, if you only de skin once, then the extra step required by the Marker won't matter.

I'm currently skiing BD Methods. I generally like the fit (maybe a touch snug in the toe/forefoot) - will the Prime have similar fit and sizing?

Best Answer Responded on

I have the Methods right now as well, and just for fun, I tried these on. The sizing was identical to me, but I didn't notice any snugness in the toe and forefoot like I do as well in the Method.

Posted on

Is this enough of a boot to push around a pair of Megawatts or AMPerages on Colorado powder days? I am looking for a light weight touring boot (don't believe in the "does it all" motto for boots or skis), but don't want something that is so geared towards touring that it can't push a big pair of skis through lots of snow. Thanks!

Responded on

Yea they will be just fine. I ski them almost everyday on Bluehouse Maestros with dynafits and they rip. They are also light enough and comfortable enough for long spring days with long approaches and big lines.

Good boot good price

For my first dynafit compatible boot I had no idea what to choose. I tried on a few companies boots to get a good comparison for sizing, and price. I eventually settled on these, and haven't been disappointed. After a full season touring in these I don't feel they're to heavy for big tours. They ski really well, and also tour exceptionally well. Very Impressed.

Write your question here...how about wearing crampons with this AT boots....anyone with any experience with that?

Responded on

Almost all AT boots should work with a rigid crampon. Just make sure the toe bail will fit.

Great side hill machne...

still too heavy for the BC but a great ski area and side hill boot. Better skiing perfromance that expected.

Responded on

Really? At 7 lbs. they shouldn't be too heavy.

Responded on

If you look at Mr. Burns other postings he really likes the Dynafit TLT5 series of boots. 95% of boots are heavy compared to those. Many people enjoy the backcountry with boots that weight and heavier.

Responded on

My current boots weight 9 lbs. and I've enjoyed every minute of 100+ days in the backcountry in them. 7 lbs. will be a significant improvement and is not "too heavy for the BC."

Yes, at under 3 lbs, the Dynafit TLT5's would be crazy light, but they come with disadvantages, too (the $1,000 price tag, for starters).

Prime Impression Oart 2

Beginning again by saying that I have no experience with buying ski boots, though I used to ski when I was younger. I have never done AT skiing, but I am a serious climber, and some of my fellow climbers got me interested in doing some AT this winter and I looked into boots as my starting point. As a climber that avidly used BD gear, I ended up getting interested in the Primes. For downhill skiing, they are fine, and I have no complaints. The liners on the other hand, really need to be thermo molded in order to get a good fit. The toe shape, as it comes, really presses against the big and middle toe. I got the 27's (wear a 9.5-10 shoe) and the included liner needed some work. After molding them, they seem to really have the added space for the toes and a reasonable sock, but I haven't been able to test it out yet-but will on a 3 day trip coming up.

Awesome Tour Boot

So far I've loved these boots. I've skied them on a couple side country tours and they have been very comfortable and provide decent support. While ripping up the groomers, I can definitely feel the stifness fall apart, but I guess I'm then using them for the wrong purpose. Stick to touring and you will probably love the boot. And of course, go dynafit. I was stuck on the debate for a while and am glad I didnt succumb to fritschis.

Prime impression

Let me start by saying that I have no prior experience in buying ski boots, nor any experience in AT skiing. However, I have done enough marginal midwestern downhill (almost an oxymoron), some time out in Tahoe, and currently small results where I live currently that get little snow fall all winter. But I am a serious climber and done enough winter mountaineering that I wanted to join some of the AT skiers this winter and started by picking a boot. My first impressions thus are far mostly positive. The boot, while not the easiest to put on compared to the traditional clam shell of an alpine boot, is fairly comfortable. The liner is very beefy and comfortable due to the thick padding. I wore a very thin liner because a normal sock was just too thick-I haven't had the ability to get the liner molded for the few extra milimeters of space to be perfectly comfortable. Nonetheless, after about 8 hours of use, the liner started to break in and be more comfortable over all. The boots are light, and adjusting between walk and ski mode is straight forward and simple. Easily adjustable, and definitely made for downhill. Solid, aggressive feel compared to the average rental boot I suppose. But back to the liner-I wore, literally, a thin business sock in 15 degree weather for 8 hours, and my feet were fine on the slopes. Granted I wasn't in 5 inches of power, but, no issues with being cold (toes mildly discomfort from the break in process). Maybe its the Pebex, but it was impressive to wear something that thin for so long in such cold temps and not be cold. I got the 27's, and it was a toss up between the 27.5's, but since I couldn't try them on ( I live overseas where Blackdiamond cannot be shipped) I followed the BD size chart for 27's. My understanding is that the shell is the same size at 310mm, but the liners are different sizes. Like another reviewer mentioned, a little bit painful in the toes until molded-something I have yet been able to do-but definitely looks like will be a perfect fit once done.

Storm Trooper Approved

These are a big upgrade from my previous Garmont G-Rides. While touring, I used to suffer from blisters on the inside of my heel, just below the ankle bone. With 3 days on the Primes, no problems!

They are very light, the Boa liner closure rocks, and they tour very well. Going down, they're definitely stiff enough for me - a 200lb intermediate skier on K2 Bakers.

The fit required thermo-molding for me. I wear a US 10-1/2, so I went with the 28.0's. I have medium-wide feet and high arches. Out of the box, the boots were painfully tight in the toes, top-to-bottom. Width wasn't an issue. After cooking the liners with a toe cap, I've got a great fit. My heels do move around slightly in touring mode, but I don't think I could fit into the 27.5's, and I haven't developed any blisters yet because of the superior flex.

Responded on

How did you Thermo-mold them, was it the liners?
