crampon
KRAM-pahn/ˈkræmpɑːn/
A spiked device attached to footwear for grip on ice or snow.
Each crampon grips the icy slope as the climber steps forward.

Etymology
Old French crampoun named a brace or staple, and the English word first described a metal bar bent for fastening. The footwear sense applies that fastening function to a spiked plate that grips ice or rock.
In context
