Product Description

Featuring a 12-point design optimized for general-purpose mountaineering, Petzl Vasak crampons excel on long glacier routes and ridge traverses.
  • Point lengths are optimally set to reduce stilt effect, improving stability and walking efficiency in mixed conditions
  • Flat front points provide excellent holding power and the next two points angle forward for support while front pointing
  • Semiflexible design combines rigid support on steep angles and flex for natural walking comfort
  • Crampons adjust easily without tools, accommodating half-sizes for an accurate, snug fit
  • Low-profile Antisnow┬« plates help prevent sticky snow from balling up beneath your feet without interfering with the projection of the points
  • Flexlock binding system is ideal for boots without welts; it uses low-bulk, flexible toe and heel bindings to adapt to most boot shapes and sizes
  • Nylon webbing straps snug the toe and heel pieces securely in place without excessively squeezing sides of boots


  • Weight: 2 lbs 5 oz (920 grams)
  • Bindings: Strap-on
  • Fits shoe size: EU 36-46 / U.S. 5-12


US Retail Cost: $165

AlpinistNot suitable for steep terrain

Voted 3/5

I puchased these in June 2009 because they looked like a good option for moderate snow fields or glaciers during warm summer months when you may not want to hike in heavy duty mounaineering boots. I wanted to wear them over lightweight hiking boots.

I've only used them once so far; on Mt Lyell in Yosemite. The terrain below the summit block consisted of hard snow (when I was there) angled at ~40 degrees. That was a bit too much for these crampons as they kept popping off. (The wrap around straps won't hold your foot in place when traversing on a steep angle due to the side pressure.)

I don't recommend these crampons for slopes with more than a 30 degree angle. If you expect to be climbing steeper terrain, you should tighten the straps as much as your pain threshold will tolerate, or get clip-on crampons.

The quality and workmanship are otherwise very good and the crampons should work well for their intended use, i.e. on lower angled slopes.

JB99A much different experience...

Voted 5/5

I've had these for just over a year now. They have taken me up vertical ice with ease as well as many snow routes over 30 degrees and up the Jamapa glacier on Orizaba so I'm surprised with the above review. Maybe they just didn't fit the boots right? I have been using them with Nepal Evo's. I got this style so I can use them with boots/shoes that aren't crampon compatible but haven't yet. Overall great all-around crampons. There are better options for vertical ice but for a versatile crampon these are a good option.
