Yaktrax Diamond Grip provides aggressive traction for all winter walking conditions. Great for users that encounter transitional surfaces. Made of case hardened steel alloy and strung on steel aircraft cable, the patented Diamond Beads have hundreds of 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.
