Crampons mountaineering

Crampons are essential equipment for ice climbing and mountaineering, providing traction on glacial terrain and frozen slopes.

About this subject

Crampons are traction devices attached to mountaineering boots, designed for walking and climbing on ice and compacted snow. Invented by English mountaineer Oscar Eckenstein in the early 20th century, they revolutionized safety in high-altitude expeditions. Modern models range from rental crampons, with shorter fixed spikes, to professional versions offering adjustable length and front points for technical vertical ice climbing. Made mainly from tempered steel or aluminum, crampons can weigh between 300g and 1kg per pair, depending on material and robustness. Choosing the right type depends on the terrain: for glaciers, 12-point crampons are used; for extreme ice, 10 or 14-point versions are common. Accessories such as antibott (antitorsion) plates and binding straps are also important to prevent snow buildup. In famous expeditions like the first ascent of Everest in 1953, crampons were crucial for crossing the Khumbu Icefall. Today, brands like Petzl, Black Diamond, and Grivel dominate the market, with innovations in composite materials and quick-attach systems.

Frequently Asked Questions

How to choose the ideal crampon for mountaineering?

Consider the terrain: for glaciers, opt for 12-point crampons. For vertical ice, models with adjustable front points. Check compatibility with your boots and weight of the gear.

What is the difference between steel and aluminum crampons?

Steel is more durable and impact-resistant but heavier. Aluminum is lightweight and ideal for mountain running but wears faster on dirty ice.

Is training necessary to use crampons?

Yes, improper use can cause falls. It is recommended to learn crampon walking and self-arrest techniques with a qualified instructor.
