Get the traction you need on ice, snow, and hardpack. Kahtoola® NANOspikes® are lightweight, low-profile grippers that you wear over your boots or shoes to prevent slips and falls while ice fishing. Originally designed for hardcore runners, Kahtoola traction footwear provides serious gripping power on frozen waters, with 10 tungsten carbide studs measuring just under 1/4"L on each foot. Though small, these studs deliver a firm ice bite without stressing your feet, even when you're wearing boots with flexible soles. The technology includes an easy on/off, stretchable TPE elastomer harness with reinforced TPU eyelets, upward-facing traction plates to keep your NANOspikes securely in place, and dual-density TPU cleats at the studs for a firm, shock-resistant stride on any terrain. Flexible toe bale with recessed connections and a raised heel tab for effortless comfort. Maintains flexibility to -30°F. Simply fold in half to store when not in use.
