    What do you think about this product?

    Have questions about this product?

    Like razor sharp cat claws.

      Wow..

      These things are ridiculous. Sharp as hell.

      I tried to figure out how to make the flexlock flex. I read the instructions.. No help at all. So I went online and looked them up at Petzl.

      To make them flex you unscrew the front two screws that hold the anti balling plates. You pull the bar that lengthens the fit and let it come to the back end of the front crampon. You will see it pivots once it is in that position. Then, put the screws back in.

      The only drawback when in the flex mode is that the crampons won't collapse to be shorter when you pack them up. Plus, I now understand where people rip their gear to shreds with crampons.

      They fit perfect with the Salomon S lab X alp carbon boots.

      These are way sharper than any of the Black Diamond crampons I have.

      Yeah, I would recommend these.

      Good performance, Very poor durability

      • Familiarity:I've put it through the wringer

      I am a glacier guide and purchased these crampons with hopes they would would last for at least 1- 4 month season. The crampons are very sharp and are easy to cut a pant leg on but they move through the ice like butter and handle well. However they are not durable, the toe piece on my first pair broke within 2 months of use and during a tour leaving me at an awkward situation. Petzl replaced the set for the cost of shipping. My second set lasted about another 2ish months before a large crack again appeared in the toe piece, I contacted petzl about the issue fearing they would break again on a tour or on a mountain. However this time petzl told me they would not replace them because they were "extensively used". Pretty much all the guides broke at least 1 pair over the summer, However we give clients grivel G12's and some of those have lasted over 10 years. Better pack a spare set if you take these crampons on anything serious.

      Great

      • Familiarity:I've put it through the wringer

      Fantastic general mountaineering crampon that can also climb ice just fine. Used them several times in RMNP (Colorado 14ers) and they excelled. I have the Leverwire configuration and it works great with the La Sportiva Nepal mountain boot - easy to fit and adjust and super secure once it's been fitted to the boot. Highly recommend.

      stiff

      • Familiarity:I've used it once or twice and have initial impressions

      description says these crampons could be used with trail runners. don't do that. connector between front and back isn't flexible, so it'll hold your foot rigidly flat. I wore them with snowboard boots, and it felt like my Achilles tendon was being stretched with every step. these would probably be fine on ski boots or stiff mountaineering boots.

      damn. I must have missed that. too late, I returned them. I guess I have to start reading instruction booklets better.



      However, I don't believe that a single articulated point could ever be as effective as a flexible linkage. I replaced them with some black diamond contact straps, and they're perfect.

      Boot fitting issues

      • Familiarity:I've used it once or twice and have initial impressions

      I bought these crampons in the spirlock variety because I was interviewing for an entry level guide job and needed to fill out my equipment list. I tried pairing them with a pair of La Sportiva Nepal EVOs and had problems getting them to fit tightly in the back. As far as I could tell the two heel tabs were too far apart (and the boot's heel was too narrow) to make a tight connection. With the heel bail out of the boot's welt the heel points ended up right under the center of my heel, instead of behind it, by the time both the heel tabs made solid contact. With the bail connected a moderate amount of force (probably standing on a slope) would have made the heel shift side to side, and possibly loosen the whole attachment. This is a problem I would expect on all the styles besides the flexlock (which I also tried and was only able to get two the three heel tabs to make contact at any time).



      This was the the first set of crampons (and boots) I owned instead of borrowed, so if I did something wrong I'd like to hear it. I think it's very strange that the most popular boot and most popular crampon wouldn't work together, so it's very possible I messed up the attachment.

      The heel tabs on the Vasak seem to be relatively wide. I use them on snowboard boots without issue. I really like these for the very hard summer alpine starts, so they're becoming my summer mountaineering crampon. Will bend the rear tabs in slightly to fit my Scarpa Charmoz firmly. I doubt petzl recommends this, use my stupid advice at your own risk. "YMMV"

      Work well from Nevada to Alaska

        I have been using these for years and just got another pair (the first pair got stolen on Mt Hood, hope they work as well for them as they did me). I am old fashioned and a very hard Judge on equipment. I only wear Galibier Super Guide boots and only Vask 12 points. This combo has not failed me form the Coast Range Alaska to the Ruby's in Nevada and the Alps. If they make a better crampon of this type it is not out yet.

        These have done well on vertical ice as well as mixed climbs and just going up or down when the need arises. At 54 I won't change my ways or equipment and these are the cats meow...

        the Snowboarders crampon!

          The flexlock Petzl Vasak's are the best fitting crampons i have found for snowboard boots. I've had problems with both blackdiamond contact strap/neve strap crampons as they don't come up the back of the boot high enough. Making for risky situations when your crampon slips off mid climb! Not an option! The strap system on these petzl's accommodate snowboard boots much better in my opinion. The back part of the strap comes up the boot about 4.5" which makes for a really solid hold.

          These things strap down so snug and tight- Snowboarders in need of crampons, look no further!

          the Snowboarders crampon!

          Will these work with my scarpa Mont blancs? Thanks!!

          Which option would work best with the Black Diamond factor 130's?

          Unanswered Question

          I purchased these crampons with the Flexlock binding. I have flexible winter boots, so I set the linking bar to "articulated" mode per the instructions. However, now I cannot compress the crampons for storage or transport. i.e. the front and back parts no longer slide together. So they do not fit in the Petzl Fakir crampon bag that I purchased with them. Is the a known issue, or am I doing something wrong?

          Was given a pair of these by a NPS Ranger, what is a good hiking and mountaineering boot that go with these?

          Congrats on the score!

          Since they're strap style, they'll work on any boot. Take that with a huge grain of salt.

          While strap crampons will work with regular hiking boots on lower angles, they are too flexible for effective crampon use on steep grades where you may need to front point. Your calves will be screaming in no time.

          For general light mountaineering, a semi-flexible full shank mountaineering boot will work. I use La Sportiva Makalu's for non technical terrain, but that's because they are a good fit for my foot. A mountaineering boot by a reputable maker in the $250-$350 range is a good place to start.

          If you're looking for some serious mountaineering where you'll find yourself on glaciers, the minimum I'd reccomend is a heavier boot like La Sportiva Nepal or Scarpa Mont Blanc for single boots and, of course, any sturdy plastic double,

          Every maker makes their boots a little differently. I reccomend trying as many brands and styles as you can to get the best fit. It helps tremendously to have a competent shoe/boot salesperson to properly measure your feet and find you the best fit. The existance of your toes may very well depend on it.

          Ill be doing some light hiking and mountaineering in them, but I also have plans on summiting Gardner, Adams and Rainier this summer with the same ranger that gave them to me. (If time allows). So need a good all around boot. I would ask the NPS Friend, but he is a difficult one to get hold of.

          La Sportiva Batura is a winner too. It's built on the Nepal last, but features a zip up neoprene cover for waterproofing and insulation.

          this boot, along with the Nepal, doesn't feature an inner boot (or liner) so you don't get the nice warm slipper for camp. Plastic double boots do for an affordable price. Top of the line boots like the Scarpa Phantom, La Sportiva Olympus Mons also feature an inner boot, adding warmth and avoiding exposure when donning/doffing. But you didn't mention the Himilaya and these cost many monies.

          Has anybody swapped out the toe-bail on the level wire for the telemark-specific toe-bail that Petzl sells?

          To answer my own question, yes, I've done it; yes, it works. Swapping out the toe-bails on them sucks: I had to use a pair of vice-grips and a bench vice to make it happen, since the spring-steel of the toe-bail is pretty stiff, and there's not a lot of room to move in the design. Still, doable with about half an hour's work

          These work really well for my tele boots, but I have had a few problems with my AT boots. I have them fitted correctly, but the prong at the back of the heel sometimes slides around and into the tech heel groove. Am I doing something wrong or should I just file the thing off?

          Thanks for the advice, but unfortunately I have the Flexlock style so there isn't any snap system. I took another look at them last night, and they're certainly tight, but the heel isn't wide enough to make contact with the rear "prong" and the two side posts (to which the rubber harness attach). I also could generate enough force in my basement to get them to slide around like they have on hard snow and ice. Maybe the boot is just too small. It's a Garmont Radium Mondo 28, for the record. I'll see if I can upload a picture tonight or tomorrow.

          Is there a way to convert from Flexlock...

          Is there a way to convert from Flexlock to Leverwire attachement by buying spare parts?

          You’re in luck, sort of. The Flexlock version does have the holes where the Leverwire’s toe and heel bail points attach. No one sells these individually, but you may be able to call Petzl directly and order some. Your crampon frames will still have the front and rear posts where the Flexlock system attaches, but they won’t really be in the way. You could always cut them off if it bothers you. My suggestion, however, is to simply buy a pair of Leverwire crampons and hang onto your Flexlock ones. I have three different pairs of crampons that I use for various things, and I still dropped dough on a full-strap model this fall for ski mountaineering and early spring rock routes with steep snow approaches. A full-strap crampon can be used for nearly anything. One day you’ll reach back into your close and be happy that they’re still there.

          I realize your post was from two years ago... But if you (or anyone else for that matter) are interested in trading your flexlocks for my leverlocks, I'm absolutely down. The leverlocks don't fit my boots. I contacted Petzl and they WILL NOT sell spare parts for these crampons.

          Is buying a semi-auto crampon getting the worst of both worlds (strap-on/step-in) or do they hold their own with a secure fit. I'm trying to somewhat base the decision of buying mountaineering boots by what kind of crampon it can accept

          Best Answer

          Not getting the worst of both worlds; getting time saved as long as you are using a pretty burly mountaineering boot. In my experience, the wire toe bail step-in only works WELL with full plastic boots and other super rigid ice boots that have a hard plastic fitting in the toe. However the new style plastic binding e.g., Grivel "new-matic" is a VAST improvement all around and works with almost anything. This binding WITH the heel lever is VERY secure but be sure your boot is fairly rigid with a robust lip back there to mate up with the heel lever. The real benefit of the new-matic style binding is that the crampons go on quickly as opposed to ten minutes per foot as with the old SMC strap-on. (The old style is still the most secure and still the best for soft backpacking style boots on low angle stuff.) I have used the Grivel with a heavy Vasque boot for steep ice and other stuff without incident...at least no incidents that were the crampon's fault. They are all equally good when kicking yourself in the back of the leg. Hope this helps. Joe

          SteveH,

          I disagree with you. The Vasak Crampons by Petzl here are completely strong enough for serious ice climbing. Much depends on the boots. With a boot that has a stiff sole / Vibram type sole will work great with these cramons. Trying to climb serious ice (steep) with boots that are not stiff and fairly supportive won't work well NO MATTER WHAT CRAMPON you use.

          The key to a secure fit is to fit the crampons well to the boot (no slop) and tighten the straps firmly. This is done, once the proper length is determined, by pulling on the straps and holding them tight by putting pressure on the strap at the point where it rests on the Flexlock binding, then you can thread the strap with the other hand and tighten, then retighten it all again for a secure fit.

          I would not recommend climbing hard/steep ice with aluminum crampons.

          Hope this clarifies and helps.
