Crampons are spikes that are strapped on to the bottom of mountaineering boots for traction on snow and ice. They have 10-16 points protruding downwards about an inch in length. All crampons rely on the rigidity of the boot to maintain their stiffness. Crampons have front points which are kicked into steep ice or snow. There are four categories of crampons. Strap on Crampons use a combination of toe and heel caps to secure the crampon on the boot.
These crampons are great for basic mountaineering and fit on about any boot. A great crampon for using with your hiking boots for that short section of firm snow. Neumatic crampons have a toe cap (usually made of plastic) and a lever that fits into a heel welt to ensure a tight fit. These crampons are perfect for general mountaineering and climb ice moderately well. They fit well with heavy duty hiking boots that have a heel welt with a rounded toe.
