Your day doesn't stop because there's ice on the ground, and when you keep a pair of Yaktrax handy, you won't have to stop either. The unique spring-coil system bites into slick surfaces for positive traction over ice without tearing up the surfaces of entryway floors. Stretchable construction doesn't require any added straps or buckles to fit snugly over your boots. Pack away easily in a coat pocket. Works on any shoe from hunting boots to oxfords and loafers.
