IceTrekker Diamond Grips

Though the Polar Vortex's frigid blast has come and gone, the danger of icy walkways endures. The IceTrekker Diamond Grip offers walkers – particularly commuters headed to work in their best shoes – the ability to ensure their safety under all winter conditions. A series of hardened steel diamond-shaped beads strung on steel cables suspended by a sturdy-yet-stretchy rubber band, the IceTrekker stretches to slip on and fit snugly on virtually any style of shoe or boot. Those pointy beads provide excellent traction on both sheer ice and compact snow, making this shoe upgrade as useful on the streets of Chicago as on the slopes of Mount Rainier. Just make sure you remove the gripping "diamond' crampons before entering a building: The beads are hell on hardwood flooring. Available in four sizes to fit shoes size 5 to 14. [$42; icetrekkers.com]
