These overboots have 16 metal cleats that grasp ice, snow, and frozen terrain with each step, ensuring safe traction while protecting shoes from snow and slush during commutes in winter conditions. The overboots are insulated with 1/3" high-thermal polyurethane foam to provide optimal warmth in temperatures down to -20° F. Made of 100% waterproof 500 denier nylon, the upper extends 11" to allow trekking through snow banks while ensuring dry pant legs. The rubber outsole is flexible and allows the shifting of weight from the balls of your feet to your toes without creating strain on the sole of the foot. A quick-release buckle tightens around narrow feet or expands the cuff of the boot to promote quick insertion of any low-heeled shoe.
