Run across slippery, frozen surfaces with ultralight, low-profile traction. Like studded snow tires for your feet, the NANOspikesTMbite into icy sidewalks or roads while preserving shoe flexibility. The NANOspikesTMincorporate Kahtoolas Patent Pending technology to provide excellent durability, comfort, and performance in a package that is still lightweight and low profile. Dual-density traction plates utilize a durable and flexible TPU that wraps around the shoe, with harder TPU plates under the foot to disperse forces and increase comfort. Upward-facing traction nubs lock the NANOspikesTMinto the tread of the shoe to prevent unwanted movement or slippage against the shoe sole. A tapered, stepped and shock-absorbing TPU cleat surrounds each of the ten tungsten-carbide spikes (per foot) to provide unmatched durability and superior traction in a variety of conditions. Additionally, the NANOspikesTMelastomer harness incorporates more of Kahtoolas Patent Pending technology with reinforced eyelets, allowing the elastomer harness to be lightweight and low profile without sacrificing durability. Each pair of NANOspikesTMincludes a Tote Sack!
