No more sliding. Plum crampons feature a specially designed attachment mechanism that allows you to plop them in place, instead of sliding them on from the side. Hold the crampon vertically to attach/detach it from Plum bindings, and then let it fall into place. The rigid alloy frame with sharp teeth will take over from there, letting you scale otherwise too-slippery slopes. The attachment system keeps the crampon centered on your ski at all times. Mesh carrying case included.
