    Universal compatibility.

    Petzl made the Vasak 12-Point Mountaineering Crampon compatible with any ski, alpine, or hiking boot for booting couloirs and traveling glaciers. The Leverlock Vasak includes step-in Fil or strap-on Fil Flex attachments for ski, telemark, or hiking boots, and the Flexlock Vasak offers hybrid compatibility for any alpine boot with a heel welt and without a toe welt. This crampon features Petzl's Antisnow anti-balling plates and 12 points, including dual horizontal front points for enhanced purchase in solid snow.

    The Best Non-Technical Crampon!

    • Familiarity: I've put it through the wringer

    The crampons can do almost everything. I have used them on all routes EXCEPT vertical ice. I recommend these crampons for Rainier, Hood, Adams, Whitney, Baker, Tahoma and everything in between. I have actually used them on all of these mountains myself. Like I mentioned before they work great until you start to get really technical. In that case you will need to bump up to a crampon with better front points. I always recommend a crampon with 12 points for safety reasons. If the snow becomes soft, you will want the most traction possible to avoid sliding out. The weight of the extra 2 points is definitely worth it. I have these crampons in the clip and strap versions and mostly use my strap version with my hiking boots. The strap versions of these crampons and most other ones provide a great fit and are very secure. You will not see a great difference from a strap, to clip, to fully auto crampon unless you are doing very technical terrain where the smallest amount of play in the boot matters for precise kicking. I would recommend a strap version unless you only plan on using your crampons with mountaineering boots and NEVER a hiking boot.

    Let me know if you have any questions on these crampons, or any other crampons we have on the site!

    Unanswered Question

    I am buying these for my Husband who has Dynafit AT Ski boots. I just want to make sure that I need the Flex lock, is that correct? Thanks!

    I'm a bit confused on the compatibility and which to chose, lever or flex lock. I'm looking to strap these to a snowboard boot.
