Yaktrax Diamond Grip provides aggressive traction for all winter walking conditions， from boilerplate ice to backcountry snow and everything in between. Made of case-hardened steel alloy and strung on steel aircraft cable， the patented Diamond Beads have biting edges that grip in all directions. The bead assemblies are riveted to a tough rubber sling which remains elastic in sub-zero temperatures. Diamond Grips are also self-clearing， so there is no snow or ice buildup.
