Named after the sure-footed Tibetan Yak, Yaktrax® stretch over everything from winter boots to jogging shoes. Once in place, a grid of skidlock steel coils give you the traction of the famed mountain sheep on hard-pack snow and glare ice. As you walk or jog, hundreds of edges bite into snow and ice, providing stability and grip in all directions. Take normal strides instead of short choppy strides. The Yaktrax® are so effective that World Cup Bobsledders don Yaktrax® to walk up the bobsled run prior to races to inspect the ice - just to get an edge!
