Purpose built for use on hard surfaces. Ultralight and comfortable, yet tough enough to handle even the roughest streets and sidewalks. Ten low profile, ultra-tough tungsten carbide spikes per foot are integrated into two TPU plates and provide exceptional grip. The plates are flexible, wear resistant, and disperse force evenly across the footwear sole. This design results in a very low-profile fit, so there is minimal effect on running stride. NANOspikes® traction is ideal for use on lightweight running shoes. All Kahtoola traction comes with a 2-year limited warranty.
