Yaktrax Diamond Grip is our top tier traction device for anyone working outdoors in the winter. An innovative Diamond Bead design provides aggressive traction for all winter working conditions, from boilerplate ice to backcountry snow and everything in between. The beads rotate independently, helping to reduce snow and ice buildup while their low profile and extreme durability make them ideal for long-term use on any winter jobsite that contains inconsistent surfaces, such as patches of gravel and bare concrete intermittent with ice and snow. Easy on & off. Fits Men 6.5 - 9 & Women 7.5 - 10.
