Crampons

Lighter weight crampons are popular for alpine ski touring where demands are generally lower and lightweight a premium.

Crampons also use a full "strap-in" system and a "hybrid" binding that features a toe strap at the front and a heel lever at the back.

[3] To prevent snow from balling up under crampons, especially in temperatures around freezing, most models can be fitted with plastic or rubber "anti-balling" systems to reduce build-up.

Rubber models use flexion to repel snow while plastic anti-balling plates employ a hydrophobic surface to prevent adhesion.

Since crampons are tighter and have larger spikes, they are typically used for mountaineering on steep and dense snow or glacial ice in order to maintain strong traction and avoid falls, whereas microspikes may be attached to multiple types of shoes and are generally used for hiking on flatter surfaces such as snow or even gravel or dirt.
