    Get on the glacier with the Petzl Irvis FL Walking Crampons.

    Petzl designed the Irvis FL Walking Crampons to give you excellent traction for basic glacier travel while limiting the number of points to keep you pants safer from crampon attacks. These 10-point crampons get the job done on any terrain where your only other aid is an ice axe. The Irvis FL Walking Crampon's full-strap Flexlock binding system attaches to any boots. You could even strap these Petzl crampons to your running shoes in a pinch. They also include anti-snow plates to prevent annoying and dangerous snowballing in wet-snow conditions.
    • Full-strap design works with any boots
    • Horizontal front points provide extra security in steep snow
    • Anti-balling plates included
    • Item #PTZ0207

    They do the job

    • Familiarity: I've put it through the wringer

    When you are traversing hard packed glacier slopes or high in the alpine boot packing up a gnarry couloir, crampons become a necessity if you want to safely make it home to plan another trip. Sure, in some instances it probably can be done, but why risk it? These crampons are extremely simple and easy to use. I bought them for my snowboard boots and they have worked like a champ. They can also fit a variety of different footwear if you needed as well, making them extremely versatile. The instructions are pretty poor in regards to setting them up for non rigid soles (i.e. Running shoes, snowboard boots, hiking boots/shoes) but they are fairly easy with a screwdriver to get adjusted. You definitely want to have them adjusted correctly, otherwise if you run them in rigid mode with soft soled footwear, it will bend the linking bar and your crampons will most likely come off repeatedly, probably at the least opportune time as well. The anti balling plates work as described, and for the price, the versatility is great.

    Good first time crampon

    • Familiarity: I've used it several times

    I got these as my first crampon after graduating from yaktrax. They are suitable for what I use them for, steep icy trails (like the devil's path in the catskills) and glacier walking. I don't plan on kick stepping vertical ice any time soon and the Flexlock works well on my cold weather trek boots. These being the first pair of new crampons I've owned after having only used dull loners I was surprised by how sharp they actually are (naive, I know). So be prepared to rig up a good storage and transport solution as you can't just throw them in a pack.

    They work

      I the Petzl Irvis crampons for the first time for glacier travel along the summit to Gannett Peak in the Wind River Range, WY. They slipped off once, but after taking extra care to tighten them, they did not slip off again. They worked as advertised.

      Ultimate Non-Skid

        "Ultimate non-skid" as per a comment from a passer by at the trail head of our 12 mile trek. They worked perfectly for the conditions we were in (iced over snow) at San Jacinto Mtn C.A.. My girlfriend wore these and did not slip once but did tear a hole in her pants. They fit her great, were not too tight, and were very easy to take on and off. Would definitely buy a second pair as long as these ones last a respectable period of time.

        Reliable performance at cheap price

          If you need crampons for basic winter hiking these are fine and cheap. They are easy to adjust, will fit any boot (including flexible boots like my 3-season Montrails) and are fast and easy to put on. The front and back rubber bracing wraps nicely around the boot without causing any pressure points, uncomfortable rubbing or blood flow interruption (hence no cold feet). I wore them for prolonged periods both uphill and downhill and had no trouble at all. Bottom line: great value for basic winter walking / glacier crossing / etc...

          I read on a previous comment area that semi-rigid crampons are probably no good for columbia bugaboots. Last year i was primarily in snowshoes and had no issues... this year the east coast weather may prompt more direct traction? suggestions?

          Hi JohnnyK!

          Great to hear from you! The information you read previously is correct. For better traction walking around your area you might look at something like the YAKTRAX Streamtrekkers Crampon, much better suited for day-to-day usage.

          I'm looking for cheap, beginner crampons for ice climbing..Would these work, or are they only for walking?

          You could use these for ice climbing, but they wouldn't be very good. Kind of like you could use a spoon as a shovel. When you're learning how to ice climb, it's nice to have good equipment. Very quickly you'd wish that you had something more taylor made for ice climbing. Spend the extra $50 and get something with vertical front points. I particularly like the Black Diamond cyborg, but Petzl has a couple of good models as well.

          will these fit both around a size 9.5...

          will these fit both around a size 9.5 hiking boot and a ski boot to fit the same size foot? i like to do ravine skiing but i cant make it to the top with just the boots when there is ice or hard pack when it gets too steep.

          Do they come with easy instructions on how...

          Do they come with easy instructions on how to put them on? These will be my first crampons to own. I have never had any luck putting on ones I borrowed. Couldn't figure out the straps!

          These have a pretty modern design for the straps too.
          I've had some older crampons with a less intuitive system and after 8 months of not using them it would take me a second to figure it out in the dark in the tent.
          These pretty much just stay together and you pull one strap and you're done!

          Will they fit a size 13 or 14?

          Will they fit a size 13 or 14?

          It depends on the type and size of boot. It the boot your using is a low volume leather hiking boot - such as the Asolo FSN 95 in size 13, it will fit. It is a larger volume or double boot, you may need the extender bars. What I have found wearing a size 13, and have 4 pairs of crampons all if which directed me that I will need extender bars - is that if your using modern low volume leather boots - I also have size 47 La Sportiva Nepal Extremes - the direction of needing extender bars is not always spot on. I have not needed extender bars yet - crampons fit all boots no problem. However, use a higher volume boot or double boot - and I can see where the extender bars would be needed.

          could you please comment on the suitability with plastic Telemark boots? Garmont Synergy in my case.

          will these fit a Garmont Engy 4 buckle boot and a La Sportiva Glacier boot? Is there a touring crampon that will fit a teleboot and my sportiva glacier 3/4 shank boot?cheers
