Ten Concave Tungsten Carbide Spikes: A concave spike profile dramatically increases surface pressure for instant engagement on ice, while tungsten carbide construction resists abrasion up to 100 times more than steel on bare pavement

Center Plate Ridges and Directional Lugs: Center plate ridges enhance grip and stability on uneven ice and snow, while directional lugs are optimized to improve traction in packed snow during ascents and descents

Integrated Toe Bail: Inspired by the award-winning design of our MICROspikes® and EXOspikes™ traction, the integrated toe bail secures the shoe during descents and reduces pressure points at the toe

Enhanced Thermoplastic Elastomer Harness Geometry: Provides a more precise, comfortable fit on a wider variety of modern running footwear and makes putting on and taking off NANOspikes® a breeze

Low-Profile Rivet Connections: Offer a secure, durable connection between the harness and bottom plate while reducing pressure points against the shoe

Improved Heel Tab: Makes putting on and taking off NANOspikes® traction a breeze
