Ice climbing is an extreme recreational activity that requires specific tools both for success and safety. One of the most important tools is crampons, which strap to your boots and provide spikes that help you to climb most any ice-covered surface, from glaciers and rock formations to frozen waterfalls. If you are looking at purchasing crampons, there are several things you should keep in mind.
How They Work
Crampons strap to your boots to provide additional grip on surfaces where there is little or no traction. The crampon features a series of sharp steel spikes that can be driven into ice as you climb. The spikes become embedded in the ice wall, providing greater traction for your boot as you climb. The crampon also can be easily taken on and off, allowing you to traverse different surfaces on the same trip.
Choosing a Crampon
Several types of crampons are available, from lightweight models for snow walking to more heavy duty and complex designs for climbing ice. For ice climbing, durability is important, making steel the material of choice for spikes. Frontpoints, or the forward-facing points, also are necessary and should be vertical for steep ice climbs and horizontal for other ice and snow climbing. You also should ensure that your boot fits well with the crampon, or consider purchasing boots specifically for your crampons, especially if wearing them for technical climbing.
Upkeep
The spikes on crampon shoes need to be sharpened after each use, says Nancy Prichard Bouchard, PhD, from REI. This is especially important if the crampon comes into contact with rock, such as when climbing a rocky terrain. A hand file should be used on the spikes in the direction of the file's teeth. A grinding wheel or other piece of equipment that can produce excess heat should not be used, as the heat can change the temper of the steel and weaken the metal.
Safety
Safety is important with crampons both in use and storage. Before using a crampon, the bindings should be inspected carefully to look for loose rivets or screws as well as wear. When storing or transporting the crampons, keep in mind that the spikes are sharp and can rip through clothing, storage bags, climbing rope and skin. Rubber point covers or a rip-resistant nylon bag can be helpful in limiting spike damage.
