Crampons mountaineering

Crampons are metal devices with sharp spikes attached to mountaineering boots for traction on ice and snow, essential for high-altitude climbing.

About this subject

Crampons are essential gear for mountaineering on glacial and snowy terrain. Invented in the early 20th century, they evolved from simple plates with nails to modern systems made of aluminum or steel. Current models fall into two main categories: rigid crampons, used with plastic boots for technical ice climbing, and flexible crampons, lighter and suitable for snow hiking. Attachment can be via straps or automatic systems compatible with specific boots (step-in system). The front points are crucial for steep ice climbing techniques, while the lower spikes ensure stability on less inclined surfaces. Proper use of crampons requires practice and caution to avoid accidents such as snagging or premature wear. Regular maintenance (sharpening and rivet checks) is vital for safety. In expeditions to the Himalayas or the Alps, crampons are as important as the ice axe and rope.

Frequently Asked Questions

What is the difference between rigid and flexible crampons?

Rigid crampons are made of steel with limited articulation, ideal for technical ice climbing with plastic boots. Flexible crampons, usually aluminum, have a center hinge and are lighter, suitable for snow hiking and general mountaineering.

How do I choose the correct size of crampon?

The crampon must match the length and width of the boot. Most models adjust via a sliding bar or links. It is essential to test the fit with the boot before purchasing, ensuring no excessive slack or pressure points.

Can I use crampons on any type of footwear?

No, crampons require boots with a welt for secure attachment, especially in automatic models. Regular hiking boots lack this structure and can damage the equipment or cause accidents. There are universal strap-on crampons, but they still require a rigid sole.
