Crampons have larger spikes designed to penetrate deep ice on the surface, where a fall is never an option. Has a binding system, usually an elastomer harness, that is compatible with a wide range of footwear, whereas the crampon/footwear has more limited compatibility.
Hiking crampons are lighter and have shorter spikes than mountaineering crampons, making them ideal for hiking on glaciers or snow-covered terrain.
If you're planning on doing any serious ice climbing, it's important to invest in a good pair of crampons. Crampons are spikes that attach to your boots, giving you traction and stability on the ice.
