Aggressive, time-tested traction that delivers uncompromising control on steep, icy terrain. Now in its fourth generation, our award-winning MICROspikes® footwear traction has been shaped by nearly two decades of feedback and field testing to ensure lasting performance and reliability.

Backed by a 4-year warranty, this packable workhorse is built to perform season after season. Features Twelve Stainless Steel Spikes Per Foot - Strategically spaced, 0.41 inch heat-treated stainless steel spikes provide a stable walking platform and bite into the most stubborn ice and snow.
