A crampon is a metal device worn on the boots of climbers and mountaineers to provide traction on ice and snow. It typically consists of a framework with sharp points, or spikes, that dig into the surface, allowing for better grip and stability while traversing steep or icy terrain. Crampons are essential for activities like ice climbing and glacier travel. Crampons come in various designs, including those specifically made for different types of climbing, such as alpine climbing or mixed climbing. They are usually attached to boots using straps or a locking mechanism, ensuring they stay securely in place during use.
