Crampon Construction Simplified

Most crampons today feature a semi-rigid design, offering versatility across various terrains. This design provides the flexibility needed for winter walking while maintaining rigidity for moderate ice climbing. Some models even allow adjustments to the linking bar, transitioning between semi-rigid and flexible modes for enhanced comfort during hiking and reduced snow accumulation.

Semi-rigid crampons boast easier adjustability and compatibility with a wide range of boot shapes. Additional accessories like asymmetrical center bars or longer flex bars accommodate highly curved boots for a better fit. It’s worth noting that semi-rigid crampons come in left and right designs, determined by the orientation of the center bar.

Types of Bindings

1. Hybrid: Also known as semi-step crampons, hybrids combine a heel lever and toe strap. They’re compatible with boots featuring a stiff sole and a heel groove or welt. With no need for precise alignment, they’re easy to put on, especially with gloves.
2. Step-In: Featuring a wire bail for the toe and a heel cable with a tension lever, step-in crampons offer a secure fit. They’re effortless to don, even in snowy conditions. Boots must have rigid soles and a designated welt or groove on the heel and toe.
3. Strap-On: Utilizing nylon webbing straps, strap-on crampons are versatile, fitting almost any boot or shoe. Though they take a bit longer to attach, they provide a snug fit suitable for moderate ice routes. However, they lack the precision of step-in bindings.

Crampton Points

Most crampons feature 10 or 12 points strategically positioned under the instep, following the boot’s shape for optimal traction. Adjusting the front bails may be necessary to achieve the correct point extension. Some advanced models come with serrated points, enhancing grip on surfaces where standard points may struggle to penetrate. The number of points and rigidity increase as crampons transition from winter walking to technical climbing.

10-point crampons are well-suited for ski touring and glacier travel, while those designed for technical ice and mixed climbing feature aggressive, adjustable frontpoints. Waterfall-specific crampons offer configurable front points, including dual-point, monopoint, or monopoint offset options, catering to various climbing needs and conditions.

For general mountaineering, shorter frontpoints ease walking, while longer frontpoints are preferred for technical climbing. Crampons may have modular or non-modular points, allowing for adjustability or fixed configurations. Modular points are ideal for mixed rock-and-ice climbing, while non-modular points are lighter and simpler but may require replacement as they wear down.

Crampon Accessories

Anti-balling Plates: Essential for maintaining traction, crampons are equipped with anti-balling plates, usually crafted from ABS plastic, endorsed by the UIAA (International Mountaineering and Climbing Federation). These plates prevent snow from accumulating under the crampon, ensuring secure footing.

Crampon Cases and Point Covers: Protect your gear and yourself from sharp crampon points with durable rubber point covers or a rugged crampon case, typically constructed from puncture-resistant nylon. While cases offer convenient storage, rubber point covers are a more compact and cost-effective option.

Gaiters: Complement your crampon setup with sturdy gaiters to safeguard your lower legs and clothing from potential nicks caused by sharp crampon points.

Spare Parts: Ensure you’re prepared for any eventuality by stocking up on spare parts such as alternative center bars, toe and heel bails, screws, and center bars. These spare components offer flexibility in adjusting crampon flexibility or accommodating larger boots, particularly essential for remote expeditions.
