NANOspikes® footwear traction provides winter road runners with high-performance traction on icy and snow-packed city streets. Designed to allow for a natural running motion and safe transition between dry and slippery pavement, 10 wear-resistant tungsten carbide spikes bite into hard surfaces without affecting gait and/or stride. Durable and flexible dual compound TPU traction plates disperse force against the outsole of footwear, aid in snow-release, and keep NANOspikes® in place. And reinforced TPU eyelets prevent tearing at connection points, allowing the TPE elastomer harness to be lighter and stronger while remaining stretchy down to -30°F. Between outings, easily pack NANOspikes® footwear traction away in the included tote sack.
