Kahtoola NANOspikes - Best for Winter Running on Icy Roads and Pavement
A specialized, low-profile traction device engineered for road runners and pavement pounders who face persistent ice and hardpack snow during winter training.
- +Ten tungsten carbide spikes provide superior bite on black ice and hardpack snow compared to coil-style devices.
- +Low-profile, flexible design integrates smoothly with running shoes, allowing for a near-normal gait and foot strike.
- +Carbide tips are extremely hard-wearing and resist abrasion from pavement better than standard steel spikes.
- -Very short spikes are ineffective in deep snow or for gaining purchase on steep, soft terrain.
- -Can be slippery on indoor surfaces like linoleum or polished floors when entering buildings.
- -Higher price than basic urban traction devices, positioning it as a specialty tool for runners.
The Kahtoola NANOspikes are a purpose-built tool for the winter runner, addressing the specific challenge of maintaining traction on icy roads and paths. Unlike bulkier hiking crampons, the NANOspikes feature a minimalist design with ten small, tungsten carbide spikes per foot mounted on flexible plates. These spikes, only 0.21 inches long, are the key to its performance. Tungsten carbide is significantly harder than stainless steel, allowing the points to bite decisively into slick ice and hardpack snow without quickly dulling from contact with patches of bare pavement. This makes them far more effective on ice than Yaktrax-style coils. The overall construction is exceptionally lightweight, and the harness is designed to fit snugly over running shoes without creating pressure points or altering the shoe's feel dramatically. This allows runners to maintain their natural stride and cadence, a critical factor for training efficiency and injury prevention.
The flexibility of the underfoot plates and the shock-absorbing quality of the spike housing contribute to a comfortable ride over mixed surfaces. However, this specialization defines clear boundaries for its use. The short spikes provide almost no benefit in deeper snow; they simply cannot penetrate to find solid purchase. They are not intended for trail running in variable snow conditions or for any kind of steep, off-pavement travel. Another practical consideration is that the carbide tips, while great on ice, can be dangerously slick on indoor flooring. Runners must remember to remove them before entering stores or homes. For the dedicated runner who logs miles on plowed roads and bike paths where unseen ice patches are the primary hazard, the Kahtoola NANOspikes offer targeted, reliable, and comfortable traction that balances security with the need to run naturally.
