No need to permanently alter your running shoes for the winter by drilling screws directly into them! From the makers of the ever-popular MICROspikes comes this new, lighter-duty traction device that’s ideal for trail running, particularly on harder surfaces such as ice or hardpacked snow. The NANOspikes are nearly half the weight of the original, cleat-like MICROspikes—and rely on tapered and stepped cleats with 10 low-profile tungsten-carbide spikes. Beware, though: with only three sizes available, fitting from a women’s 8 up to a men’s 12, these won’t work for everyone’s feet.
