Live in Minnesota, Montana, or Maine? This is the winter training shoe for you. With 16 carbide-tipped spikes protruding from the outsole, these sturdy snowcats provide reliable, no-slip traction on iced-over trails and snowpacked roads. "Amazing," said one tester, "I've never felt so confident going downhill on icy trails." 10.9 oz; garmontusa.com
Bonus: While running through spring snowstorms in Wyoming, we found the highly water-resistant upper to be almost impenetrable to slop yet still plenty breathable.
Bummer: When the snow and ice melt, these shoes stay in the closet.
