The lightest 12 point crampons in the world! Absolutely perfect for competitive ski mountaineering and glacier travel. Innovative 3 D shaped construction pressed not just bent on the front platform distributes pressure applied to one point across the entire platform significantly increasing the strength and durability of the crampon. While sturdy, aluminum crampons are not suitable for ice climbing or intensive mixed terrain. We recommend the automatic binding style rather than semi auto or universal for stiff boots with full toe and heel welts, especially all T and telemark ski boots. Automatic bindings are also the most secure configuration for alpine climbing.
