Slick roads, freezing temperatures, and fading daylight call for traction built to keep you moving confidently all winter long. Purpose-built for hard surfaces, NANOspikes® footwear traction is low-profile, yet tough enough to handle icy streets and sidewalks. With ten ultra-durable tungsten carbide spikes per foot and streamlined rivet connections, this ultralight traction delivers impressive grip without sacrificing comfort.

• Ten Concave Tungsten Carbide Spikes - Concave spikes increase grip on ice. Tungsten carbide is up to 100 times more abrasion resistant than steel and delivers unmatched durability on hard surfaces.
• Center Plate Ridges and Directional Lugs - Center plate ridges enhance grip and stability on uneven ice and snow. Directional lugs improve traction in packed snow on ascents and descents.
• Integrated Toe Bail - Secures footwear during descents and reduces pressure points at the toe.
• Enhanced Thermoplastic Elastomer Harness Geometry - Provides a precise, comfortable fit on modern running footwear. Features patented reinforced eyelets for increased durability and retains its elasticity down to -22°F (-30°C).
• Includes tote sack
