Petzl Leopard Crampons


In Stock

Free shipping

The Leopard is a lightweight, aluminum crampon with a unique linkage Petzl calls Cord Tech. By eliminating the metal linking bar that is traditionally used between the toe and heel of the crampon the weight, and especially the bulk, of the crampon are greatly reduced. These are the crampons you forget are in your pack and won't hesitate to have with you just in case. Much easier to put on than other foldable race-style crampons, the Petzl Leopard can be used in races or light-n-fast ski mountaineering where you may need to put them on in dicey situations.

  • 10-point design is optimized for glacier and snow travel.
  • Tool-free length adjustment uses a simple cord re-routing.
  • Two binding options: LeverLock FIL and Flexlock.
  • Comes with protective carry bag.
  • CE certified for mountaineering.

Leopard LLF - Lighter LeverLock FIL automatic binding is suitable for boots with toe and heel welts. Ideal for use with most ski touring boots.

Leopard FL - FlexLock binding can be used with all boots with or without toe/heel welts (e.g. TLT7). Can even be used on hiking and approach shoes.

I have a pair of these in the FlexLock style. I've used them with my Atomic Backland Ultimate boots, with trail runners, and with Salomon S-Lab X Alp Carbon Gtx Boot. These are great all around crampons. I most recently used them on Ski Mountaineering trip to the summit of Mt. Hood. These crampons provided excellent performance climbing the Pearly Gates. I've also used them to summit Mt Rainier.

All around great cramp-on!

Question from Erik K
Dear Skimo.
Just got the new Alien 1.0 (or 1.1 as it is called). The fit on toe part is not really good unless I have the front welt assymetrical mounted. See picture. Any field experiance with this combo? Do you see any problems by having the toe mounted assymetrical? It does make the whole front part of the crampon a bit "inclined"/rotated, but it seems securve when hand flexing it.
Best regards.
Answer from Cole P
Erik, thanks for reaching out, that shouldn't be a problem in the field as long as your heel lever snaps firmly, but I think we can get the crampons fit by adjusting the toe bail. To get the crampons straight I recommend fitting the bails symmetrical and then bend the toe bail little by little until your crampons fit the boot properly. If you would like further help email us at help@skimo.co.

Question from Tyler
Is it more important for the crampon heel to line up lengthwise with the boot heel (left), or for the crampon heel posts to fit snugly around the heel of the boot (right)? I'm guessing the latter but I'm not sure. Apparently the Backland Pro has a pretty narrow heel.
Answer from Teddy Young
Hey Tyler, as long as the heel lever snaps firmly, both should be secure. That being said, I tend to prefer the latter to eliminate the possibility of any side-to-side play!

Question from Chuck
Has anyone tried the flexlock version on an Atomic Backland 30/30.5? I read somewhere that the BSL is too long for the LEOPARD FL ?
Answer from Teddy Young
Hey Chuck, I just did a FlexLock Leopard test fit on a Hoji Free 29.5 330mm BSL (we’re out of size 30/30.5 Backland Carbons currently, which are 328mm BSL). The crampon does fit, but I’m using the first cord tightening hook on one side, and none of the hooks one the other side. In other words, it’s nearly maxed out, but it should fit!

Question from Aaron Trowbridge
I'd like to get a pair of leopards for ski mountaineering and light summer shoe use. Will the FL system work well enough for my scarpa f1s or will I have to track down the individual lever lock components too?
Answer from TSB
Hey Aaron, yep, the FlexLock toe should hook up OK with the F1 so long as you tension the cord properly (see review below). The toe bail on that particular boot isn't particularly protuberant, so the F1 tends to work just as well with a "semi-automatic" rubber loop attachment as it does with a traditional metal bar-style attachment (what other brands call "automatic").

Nat (downright abused product)
I used the LeverLock version with my Scarpa Alien RS a dozen days last spring and they proved to be a great, extremely lightweight crampon. They fit well on this boot. Reading through some of the past comments of the dyneema cord "stretching" I think it's more a "seating" issue. I do agree tho - the 1st couple times you use this crampon they seem to get a little bigger on the sizing and will require some re-adjustment. I actually had my cramps fall off twice in very firm, 55-60 degree conditions and I was briefly less than psyched. For my Alien RS in 27 I needed to make an adjustment to the rear heal bail and use the other hole (creating more tension) and then I found that staggering the adjustment tabs on the rear piece enabled me to find the sweet spot. Super light and compact. After the initial break-in period and some adjustments I went on to use them in very firm and committing situations without any issue. I do notice some wear on the dyneema cord but nothing that is concerning. And I do believe that dyneema is readily available from Petzl for replacement.

Question from john red-horse
I hate coming into a relatively mature thread to ask a fit question, but I recently swapped from old-school tele boots to NTN, and I'm having to re-vamp my spring/summer setup to accommodate them.

Do either of the attachment styles of this crampon fit a Scarpa NTN boot, such as a TX Pro? My CAMP XLC 390's, toe clip edition, are totally out of the question.


Answer from Jeff
John, We don't have any Tele boots to try on the different crampons. I don't see why the toe bail will not work for those boots. The FlexLock should work, a semi automatic style should work with anything.
Answer from john r
Hey Jeff,

Thanks for the follow-up! Unfortunately, the NTN tele boots have a front ledge that fits into the toe pieces of all non-tech style tele bindings, and I've seen for myself at least one crampon with semi-auto attachments that does not accommodate that ledge: Grivel Air Tech Lights -- the non-wide version. That is why I'm asking the question more generally for other makes/models of crampons.

Question from Eric A
Hey Skimo team, do these fit well on the Solomon X-Alp ski boots?
Answer from Teddy Young
Hey Eric, with the X-Alp having toe and heel welts, the LeverLock FIL option should be a good choice. I just tested out that combo, and it looks like a great fit! Make sure to adjust the cord very tight for a nice snug fit, as the cord stretches just a bit.

Question from Julie D
Will the FlexLock version of the Leopards work with Dynafit TLT7s without the Dynafit crampon adapter? Or is the adapter still needed? Thanks!

Question from Trent S
Will these fit and work with 30/30.5 Tecnica Zero G Tour Pro?
Also, is everyone adding on the antisnow plates?
Answer from Trace Leches
Hey Trent! They will definitely work with the Zero G Pro Tour. Anti-balling plates are kinda personal preference. I have never added them, but maybe I've just gotten lucky with snow conditions so far.
Answer from Trent S
Thanks for such a fast response.
Answer from Trent S
Weights are without the anti-balling plates? If yes, are the AB plates for these about the same weight as those for the Irvis Hybrid?

Jonathan S (used product a few times)
This is my sixth pair of aluminum crampons over the years, but my first pair not made by CAMP. I still love my CAMP Race 290, and I will continue to use them with my PG boots.
But I wanted to start using my Alien 3.0 boots for some spring and summer ski mountaineering, and their boot sole is longer than my PG boots.
The Race 290 takes hours to adjust back and forth between boots, and I even considered buying a second pair, but having two pairs of dedicated Race 290 crampons seemed a little bit too strange.
(Even for me...)

So the Leopard LeverLock FIL seemed to offer nearly the same ultralightness and storage compactness of the Race 290 while adding easy adjustability – and indeed it does!

Adjustment out of the box was nearly instantaneous, probably the easiest of any crampon of any type on the market. The attachment point of the heel lever onto the crampon frame is also easily adjustable. The attachment point of the toe bail onto the crampon frame is adjustable too, but takes some effort, which I didn’t bother with since the stock position seemed fine.
The toe bail shape is very secure, with less slop than the CAMP version.
On the Alien 3.0, the heel lever fits fine, although more secure when slightly asymmetrical, so just have to remember upon each attachment to move the lever off to the side ever so slightly.
As for complaints regarding the Dyneema cord’s initial stretch, I don’t think this is quite accurate, as the inherent properties of Dyneema include minimal elongation. Instead I think what’s happening is that the cord “seats” itself more in the notches after some use. Based on that premise, I made sure the fit was as tight as possible during initial setup, and indeed it was fine in the field.

My only complaint is that I wish the outside color of the ankle strap were orange (as it is on the inside) instead of black for better visibility. Otherwise, this model combines the best of a traditional attachment system (both security and adjustability) with the weight and storage compactness of the Race 290.

Bootpacks made easy!

Sure, you can boot up a slick/firm slope without crampons; but when having the option in your pack weighs less than your phone, and packs down smaller than a pair of goggles, it's just silly to not have these crampons.

These crampons are so light and compact; if there is even a remote possibility of a slick/firm booter I do not hesitate to toss these in my pack.

Easy to adjust, easy to don/doff, and secure and stable with no heel or toe movement.

Upon first use and before charging up a steep icy chute, I recommend: taking a brief stroll in some snow to get the dyneema wet and allow for its initial stretch; tighten the crampons from initial stretch; and toss in pack for the season and enjoy! This initial adjustment only needs to be done once.

I have paired these with the Movement Alp Tracks boot (love that boot see reviews). The toe bail and heel welt fit perfectly, but I had to grind down the lever lock a few mm to allow for full boot walk-mode articulation. The lever lock mechanism had plenty of extra material, and this small grind (which is not required for nearly any other boot) did not affect the durability of the lever lock.

The Dyneema stretches a bit initially, so it takes a few adjustments to fit securely to a specific boot. Once the Dyneema is broken in, it doesn't continue to stretch. These fit the Scarpa Alien 1.0's perfectly.

Question from Trevor J
Hi guys, how do these pair with the Alien RS?
Answer from Trace Leches
Hey Trevor! Really well unless you want to front-point in ski mode a lot!
Answer from Trace Leches
Here's a pic of the heel, right out of the box.
Answer from Trace Leches
Here's the ski/walk locking nubbin. You can see how close it is and it doesn't allow for ski mode without some pretty generous modification to the ski/walk lever.
Answer from Trace Leches
Here's the toe bail. These crampons fit really well out of the box but could do with a bit of adjusting to get it perfect. No complains here though.
Answer from Trevor J
Awesome, thanks alot for the pics i appreciate it. nice to know that could be an option i had thought it wouldn't be.
Answer this question:

Eric (downright abused product)
The only pair of crampons one can really compare these to are the CAMP Race 290 Dyneema. Compared to those, adjusting these is freaking simple. The key is to adjust them super tight, then squeeze the dyneema cables together to work out the play. I swap them back and forth between different boots and it just takes a couple of minutes to dial it in. Compared to the hassle that was adjusting the CAMPs these are a dream. They also sit much more securely on your foot than the CAMP. The toe *barely moves at all because the cable connects in two places. I've used them on PG race boots (where they don't interfere with the heel throw lever!), PDGs, Fischer Travers, and Vulcans and not had any fit issues. Additionally, with the strap on system, they fit great on running shoes. Durability is as expected for aluminum. Definitely not designed for rocks so I only use them if I only expect to boot up snow or for races. Running though some rocky sections at Adamello and a couple of World Cups didn't seem to affect them too much. My dyneema cord is a bit fuzzy after a season but doesn't look sketchy yet. I'm hesitant to replace it until it seems necessary but it would be a bummer to blow one. They seem to rub a bit on Billygoat Ascent plates but that could just be how I've set them up...

I’ve been very pleased with the performance and compact storage of these crampons.

Choosing to take crampons has always required extra planning due to their bulk. Usually I need to bring a bigger pack or find a way to lash them to the outside. With the Leopard, I find myself throwing them in my normal pack even if there’s only an off chance of needing them. No need for extra accommodation. They are so light and so compact that in the pack they aren’t any more noticeable than my ski crampons.

The Dyneema linkage between the heel and toe are simultaneously the biggest advantage and weakness of these crampons. The Dyneema saves weight and enables their small packaging, but stretches out through the first few uses. This means that you must spend extra time and attention to the fitment of your crampons each time you put them on AND while wearing them. Something that can be a distraction at a time where you’d rather not be thinking about your gear. After several usages, this problem ceases. The cord settles into a final adjustment and no longer needs fiddling. For this reason, I’m giving them 4 stars instead of 5.

In terms of durability, they are on par with other aluminum crampons and the typical caveats apply. Avoid rocks as much as possible and don’t expect to be front pointing up technical ice.

A bit fiddly to get setup (perhaps the only crampon that needs to be broken in), once dialed in these spikes are a thing of beauty. The flexible instep lets them fold in half, clip easily to a harness, fit in a pocket, or just generally disappear into a pack. Weight is excellent, and once they're dialed, they're much more secure than the camp options that use a tech heel. It's impossible to get the cord adequately tight when adjusting by hand, so they need to be adjusted, put on the boot, and retightened after some use to make them truly secure for a given boot size. Thankfully, theyre field adjustable without tools. Once dialed in, the fit is very confidence inspiring, with no slop (paired with an F1 in my experience). The dyneema cord has fuzzed a bit after some agressive use, and I wouldn't hike them around on the rocks, but otherwise, durability is good. The weight and convenience are tough to beat.
