Kahtoola NANOspikes® Automatic Crampons

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.

Features:

- 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
