Slick roads, freezing temperatures and diminishing daylight call for traction with unmatched fit, performance and comfort. Redesigned from the ground up, NANOspikes® footwear traction now delivers enhanced comfort, improved grip and a better fit on a wider variety of modern running footwear. So you have the freedom to keep moving confidently on icy streets and sidewalks, all winter long.

• 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
