YakTrax Walkers consist of stretchy, slip-on devices that conform to the length and width of nearly any shoe or boot. Feature hand-wound coils that provide 360° traction on ice and snow. Direct hundreds of biting edges onto surface to keep wearer from slipping and falling in inclement weather. Can be worn in temperatures as low as -40 F. Wearer just walks naturally, as when traveling over dry surfaces. Choose from men’s and women’s sizes. Compact size fits in glove compartment or purse. Optional water-resistant carrying bag available. Andax Industries LLC, Saint Mary’s, Kan.
