Yaktrax Diamond Grip provides aggressive traction for all winter walking conditions, from boilerplate ice to backcountry snow and everything in between. They're also effective when transitioning through gravel, rock, and mud from icy surfaces. Made of case-hardened steel alloy and strung on steel aircraft cable, the patented diamond-shaped beads have hundreds of biting edges that grip in all directions. The beads are designed to swivel independently, preventing the build-up of snow and ice. The bead assemblies are riveted to a tough rubber sling which remains elastic even in subzero temperatures. Diamond Grips are easy to put on and take off, yet fit snugly and stay on without the need for additional straps. Imported.
