For the ultimate performance on radically overhanging terrain, the Raptor crampon bolts directly on to dexterous boots with welted soles for an absolutely solid boot/crampon connection. Its aggressive, adjustable heel spur supports full body weight while heel hooking. A modular mono frontpoint lets you adjust positions and replace rock-worn points. Specs: Weight: 60 G (1 LB 4 OZ) Sizes: One size fits all.
