Irvis 10-Point Crampon

Petzl made the Irvis 10-Point Crampon compact, light, and thin for ski touring and mountaineering expeditions. This 10-point crampon has two wide front points to provide a solid purchase on steep couloirs and icy glaciers, and there are Antisnow anti-balling plates for a better performance. The Irvis Leverlock includes step-in Fil or strap-on Fil Flex attachments, and the Irvis Flexlock offers hybrid compatibility with any with a heel welt and without a toe welt.

Great if you have smaller feet

Familiarity:
I've used it several times

According to the other reviews, I should have no problem getting into the crampons. However, my size 9 boots have difficult fitting into these crampons even when the crampons are adjusted to maximum length. Maybe my boots just have especially thick soles, but I have to bang my boot into the metal fittings on the crampons to make them fit. Other than that, the crampons provide plenty of traction on snow, and the bar is easy to adjust from one length to another.

Hey Jeffrey, These guys do max out around a size 42 using the standard linking bar that comes with the crampon. For larger sizes, you can pick up the Barrette linking bar - https://www.backcountry.com/petzl-barrette-linking-bars?s=a which will work up to a 46 . In regards to wider boots, I use these with snowboard boots and have to do the same thing. However, I've found that to be the case with most other crampons on the market as well. I hope you continue to enjoy these - great lightweight ski mountaineering and glacier option. Best, Geoff

I had the same problem as Jeffrey. I tried the Barette linking bars mentioned in Geoff Conner's post but they weren't any longer than the ones that came with the crampons.

Not for large feet/boots

Familiarity:
I returned this product before using it

The Petzl Irvis crampon is not built to support boot sizes over EU 45 or US 10.5. They also do not make an extender base plate bar to adjust for this size fit. Consider the Back Country or Grivel set as they have base plates that work. Attached is a photo of my size 11.5 boot, 13.5" sole length which does not fit into the crampon frame. Know before you buy and have to return.

Good crampon for ski mountaineering

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

I fitted these crampons to a pair of Scarpa Maestrale RS ski boot. The fit was very good, I used the heel lever lock and the included front metal bar attachment. They seem like a good basic crampon, light, rugged, "auto step in" attachment, and includes the anti snow balling plastic plates on the bottom.

What size of boot do you wear? I wear a mondo 28.5. As well how much larger can the crampon be adjusted from where you had it on your boot?

Read this if you've got large feet

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

These are some of the lightest all-steel crampons on the market, but unfortunately Backcountry.com doesn't mention that they won't fit boots larger than Euro size 45 (US 11.5). With older models It used to be possible to buy longer-size linking bars, but apparently not any more.

Does Leverlock or Flexlock fit non-tech boots?
