Frigid temperatures, snow and ice don’t mean you have to forgo your cardio fix.

RUNNING
1. Ahnu Firetrail Winter

Ideal for slush and mud, this shoe provides just enough waterproofing—in the form of a breathable hydrophobic mesh—to shuck off the nastiness without deviating too far from a standard trail runner. The Vibram sole and special lug pattern provide extra traction on slippery rocks. $120; ahnufootwear.com

RUNNING SPIKES
2. La Sportiva A.T. Grip Hobnails + Tools

Don’t want to buy a whole new winter trail runner? This nifty tool set provides studded tires for your favorite rubber-soled shoe. Come spring, they screw back out. $45; sportiva.com

SPIKING
3. Kahtoola Microspikes

Most of the time when you go “snowshoeing” in the Front Range, you really don’t need the snowshoes. The trails are icy, yes, but those big planks on your feet are overkill. These portable spikes are the answer—simply stretch them onto your favorite winter boot and you go hiking past the snowshoers. $59; kahtoola.com

SKATE SKIING
4. Fischer RCS

Featuring World Cup sidecut and light, smooth performance, Fischer’s RCS series was designed for racing, but they’re ideal for Front Range fitness freaks. $535; fischerskis.com

SNOWSHOEING
5. Crescent Moon Silver

This multi-purpose snowshoe will get you out exploring the woods and/or working up a sweat. The aluminum crampons provide plenty of traction and the cam-locking buckle system is user-friendly. $175; crescentmoonsnowshoes.com

FAST SNOWSHOEING
6. Atlas Run

Weighing in at just 2.7 pounds and featuring a spring loaded suspension that allows for a natural running stride instead of that snowshoe shuffle, the Run is the ideal shoe for putting down some serious cardio miles on snow-covered trails. $200; atlassnowshoe.com
