Crampons
Crampons are the difference between safe and unsafe travel on ice and hard snow. For NZ alpine tramping, glacier travel, and winter mountaineering, a quality pair of crampons matched to your boots and the terrain is non-negotiable kit. Getting this wrong — wrong type, wrong fit, or wrong technique — has serious consequences in alpine environments.
Our crampon range is led by Grivel — Italian-made ice and snow equipment trusted by alpine guides across NZ and internationally.
Crampon Types
- C1 — Flexible crampons: Compatible with most hiking and tramping boots (flexible sole). Suited to glacier travel, firm snow, and winter day walks. The most versatile option for general NZ alpine use. C1 crampons use strap bindings and fit a wide range of boot types.
- C2 — Semi-rigid crampons: Require a boot with a semi-stiff sole and a rand (lip) at heel and/or toe for the bail binding to grip. More performance-oriented — suited to technical alpine routes, ice climbing approaches, and mixed terrain.
- C3 — Rigid crampons: Require fully rigid mountaineering or ice climbing boots with front and rear welts. For technical ice climbing and serious winter alpine routes — not for general tramping.
Getting the Right Fit
Crampons must be sized and adjusted to your specific boots. A poorly fitted crampon can come loose in critical terrain — potentially catastrophic. If you're new to crampons, bring your boots in-store so we can confirm compatibility and fit correctly. Key checks: the crampon frame length matches your boot sole, the bail or strap binding is secure with no movement, and front points align with the toe of your boot.
Frequently Asked Questions
Do I need crampons for NZ tramping?
For most NZ Great Walks and three-season tramping on well-formed tracks, no — crampons aren't required. They become necessary for: glacier travel (Franz Josef, Fox, Tasman Glacier), winter alpine routes with icy terrain, any route above the snowline in shoulder season or winter, and technical mountaineering. If your route involves sustained travel on hard ice or snow, crampons are essential safety equipment. Check DOC's current track conditions and your guide's recommendations before deciding.
How do I know which crampon type is compatible with my boots?
Boot-crampon compatibility is critical. C1 (flexible) crampons with strap bindings fit most hiking and tramping boots with a flexible sole. C2 and C3 crampons require specific boot features — a stiff or rigid sole and a pronounced rand at the toe and/or heel for the bail binding to grip. Check your boot's sole flex: if you can bend it easily, it's C1 compatible only. If you're unsure, bring your boots in-store before buying — fitting crampons to the wrong boot type is a safety issue.
What are anti-balling plates and do I need them?
Anti-balling plates (also called anti-bott plates) are rubber or plastic inserts fitted between the crampon frame and the boot sole. They prevent snow from balling up between the crampon points — a dangerous build-up that reduces grip and can cause a slip. In wet, sticky snow conditions common in NZ's spring and autumn alpine environments, anti-balling plates are strongly recommended. Most Grivel crampons include them or offer them as an accessory.
How do I care for crampons after use?
Rinse with fresh water after use in wet or coastal conditions and dry thoroughly — salt and mud accelerate corrosion on steel points. Check points for wear or damage after each trip; replace worn or bent points before they fail in the field. Store dry, loosely in a crampon bag (included with Grivel crampons) with point guards fitted to protect the points and your gear bag. Apply a light coat of oil to steel components if storing for extended periods.
Do I need an ice axe if I'm using crampons?
In most situations where crampons are required, an ice axe is also necessary — crampons provide grip on ascent and traverse, but an ice axe is your primary arrest tool if you slip on steep terrain. They work as a system. Glacier travel with a guide or experienced group may only require crampons on lower-angle ice. For any route with genuine avalanche terrain, steep snow, or technical alpine conditions, carry both and know how to use them. We can advise on ice axes to pair with crampons — see our alpine gear range.
