What Our Gearhead(R) Experts Are Saying:"I wore these on an icy trail run in early winter and never once felt my feet slip out from under me. They're so light and packable that I started throwing them in my vest even on shoulder season runs with muddy sections."Icy trails have a way of turning a confident run into a cautious shuffle, and the Trail Spikes are built to hand that confidence back. Pull them on for a winter run or hike over hardpacked snow, and the 7. 5mm spikes bite into ice and compact trail with almost no extra effort on your part. They're not just a winter tool either, slippery mud and loose rubble in the off season disappear underfoot just as easily. The slim elastomer rubber stretches to fit snugly over lightweight running or hiking shoes without changing how the shoe feels underfoot, and the minimal weight means you'll barely notice they're on. Packed down small enough to live in a vest or pack pocket, they're the kind of gear you carry just in case and end up using more than expected.
